Design Tablet-Optimized UI in Flutter

CodeTrade India Pvt. Ltd. — Mon, 05 Aug 2024 10:57:07 +0000

There are two main ways to design a tablet-friendly UI in Flutter:

Using the ‘responsive_builder’ Package: This package allows you to define different layouts for different screen sizes.
Using the ‘MediaQuery’ Widget: This widget provides information about the current device and allows you to adjust your UI layout accordingly.

Method 1: Using ‘responsive_builder’ Package

Step 1: Set Up Your Flutter Project

Create a new Flutter project or navigate to your existing project.
Add the ‘responsive_builder’ package to your ‘pubspec.yaml’ file:

dependencies:
  flutter:
    sdk: flutter
  responsive_builder: ^0.7.0

Run ‘flutter pub get’ to fetch the package.

Step 2: Implement responsive_builder

Import the Package:

import 'package:responsive_builder/responsive_builder.dart';

Utilize the ‘ResponsiveBuilder’ Widget:

Wrap your existing widgets with ‘ResponsiveBuilder’ and use it to define different UI elements for mobile and tablet.

Container(
  padding: EdgeInsets.all(getValueForScreenType<double>(
                context: context,
                mobile: 10,
                tablet: 30,
                desktop: 60,
              )),
  child: Text('Best Responsive Package'),
);

getValueForScreenType<bool>(
    context: context,
    mobile: false,
    tablet: true,
  ) ? MyWidget() : Container();

ScreenTypeLayout.builder(
  mobile: (BuildContext context) => Container(color: Colors.blue),
  tablet: (BuildContext context) => Container(color: Colors.yellow),
  desktop: (BuildContext context) => Container(color: Colors.red),
  watch: (BuildContext context) => Container(color: Colors.purple),
);

Adjust the UI:

Adjust the container widget’s height, font size, and layout accordingly based on the device type.

Method 2: Using ‘MediaQuery’

Utilize ‘MediaQuery’ to Detect Screen Size

Define App Constants:

class AppConstants {
  static Size size = MediaQueryData.fromView(WidgetsBinding.instance.window).size;
  static bool isMobile(BuildContext context) {
    final screenWidth = MediaQuery.of(context).size.width;
    return screenWidth < 600;
  }
}

Conditional Layouts:

Use the isMobile() function to display different widgets based on the device type.

if (!AppConstants.isMobile(context))
  Row(
    children: [
      Expanded(
        child: TextFormField(
          controller: Controller1,
          hintText: "Mumbai Date",
          onTap: (_) => _selectDate(false),
        ),
      ),
      Expanded(
        child: TextFormField(
          controller: Controller2,
          hintText: "Mumbai Time",
          onTap: (_) => _selectTime(),
        ),
      ),
    ],
  );

The ‘isMobile()’ function works by getting the width of the current device screen using ‘MediaQuery.of(context).size.width’.

If the width is less than 600 pixels, it returns true and indicates that the device is a mobile device. Otherwise, it returns false.

Issues with the ‘responsive_builder’ Package and Recommendation for ‘MediaQuery’

While the ‘responsive_builder’ package is popular for building responsive UIs in Flutter, it has some potential issues:

Dependence on the Package: If the package becomes unmaintained, it could break your app.
Complexity: The package can be complex to use, especially for large and complex UIs.
Performance: The package can add some overhead to your app, especially if used for many widgets.

For these reasons, it is generally recommended to use ‘MediaQuery’ to create tablet-optimized UIs.

‘MediaQuery’ is a built-in Flutter class that provides information about the current device and screen size, allowing you to create different layouts without relying on a third-party package.

Tips to Use MediaQuery to Create Tablet-Optimized UIs

Use ‘MediaQuery.of(context).size.width’ to get the width of the current device screen.
Use ‘MediaQuery.of(context).size.height’ to get the height of the current device screen.
Use ‘MediaQuery.of(context).orientation’ to get the orientation of the current device screen.
Use ‘MediaQuery.of(context).devicePixelRatio’ to get the device pixel ratio.

In today’s multi-device world, tablets have become indispensable companions. To truly captivate your audience, your Flutter app must seamlessly adapt to these larger screens.

By understanding the nuances of tablet UI design and leveraging powerful tools like MediaQuery, you can create immersive experiences that delight users.

Step-by-Step Guide To Install OpenCV For Python

CodeTrade India Pvt. Ltd. — Tue, 11 Jun 2024 11:16:12 +0000

OpenCV is an open-source computer vision library that provides a comprehensive set of tools for image processing, video analysis, and machine learning.

It is written in C++ and Python, and available for a variety of platforms, including Windows, Linux, and macOS. It is easy to learn and use, making it a popular choice for both beginners and experienced developers.

Steps to Install OpenCV For Python

OpenCV for Python is a library of Python bindings designed to solve computer vision problems. It is built on top of the OpenCV C++ library and provides a convenient way to use OpenCV in Python programs.

To install OpenCV-Python (also known as cv2) on your system, you can use the Python package manager pip or conda command in Anaconda. The installation can be performed in the following steps:

STEP 1. Create Environment

A virtual environment is an isolated Python environment that has its own Python interpreter, standard library, and pip package manager.

This makes it easy to isolate different Python projects and avoid conflicts between different versions of Python packages. Use the given command to create a new Python virtual environment.

$ python3 -m venv your_env_name

To create a virtual environment, you can use the ‘python3 -m venv’ command, where ‘your_env_name’ is the name of the virtual environment you want to create. For example, to create a virtual environment named ‘env’, you would use the following command:

$ python3 -m venv env

This will create a new directory called ‘env’ containing the Python interpreter, standard library, and pip package manager for the virtual environment. To activate the virtual environment, you can use the following command:

$ source env/bin/activate // env = your env name

Once the virtual environment is activated, the Python interpreter and pip package manager will use the packages installed in the virtual environment instead of the packages installed in the system Python environment.

STEP 2. OpenCV Installation

To install OpenCV use the following pip command:

$ pip install opencv-python

The command installs the OpenCV Python module using the Python Package Index (PyPI).

By following these steps, you've installed OpenCV-Python using a virtual environment. This approach keeps your project's dependencies organized and avoids conflicts with other Python projects on your system. Now you're ready to explore the vast capabilities of OpenCV for computer vision tasks in your Python programs!

How Does Grad-CAM Work in PyTorch?

CodeTrade India Pvt. Ltd. — Thu, 06 Jun 2024 11:17:46 +0000

Grad-CAM is a visualization technique that provides visual explanations for decisions from convolutional neural networks (CNNs). It produces course localization maps that highlight important regions in the input image for predicting a particular class.

How Grad-CAM Works in PyTorch

Implementation of Grad-CAM in PyTorch involves several steps, each step is crucial for creating accurate and meaningful visual explanations.

Step 1: Preprocess the Input Image

The first step is to preprocess the input image to make it suitable for the neural network model. This involves resizing the image, normalizing it, and converting it into a tensor format.

The image preprocessing ensures that the image meets the input requirements of the model and improves the accuracy of the GradCAM visualization.

from torchvision import transforms
import cv2

# Define the preprocessing transformation
preprocess = transforms.Compose([
    transforms.Resize((224, 224)),
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])
])

# Load and preprocess the image
img = cv2.imread('path_to_image.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
img_tensor = preprocess(img).unsqueeze(0)

Step 2: Perform a Forward Pass

Perform a forward pass through the model to obtain the predictions. This step passes the preprocessed image through the network to get the logits or output scores for each class.

# Perform the forward pass
model.eval() # Set the model to evaluation mode
output = model(img_tensor)
pred_class = output.argmax(dim=1).item()

Step 3: Identify the Target Layer

Grad-CAM requires access to the activations of a convolutional layer and the gradients of the target class to those activations. Typically, the last convolutional layer is used as it captures the most detailed spatial information. We register hooks to capture these activations and gradients during the forward and backward passes.

# Identify the target layer
target_layer = model.layer4[-1]

# Lists to store activations and gradients
activations = []
gradients = []

# Hooks to capture activations and gradients
def forward_hook(module, input, output):
    activations.append(output)

def backward_hook(module, grad_input, grad_output):
    gradients.append(grad_output[0])

target_layer.register_forward_hook(forward_hook)
target_layer.register_full_backward_hook(backward_hook)

4. Backward Pass

After performing the forward pass, a backward pass is done to compute the gradients of the target class to the activations of the target layer. This step helps in understanding which parts of the image are important for the model prediction.

# Zero the gradients
model.zero_grad()

# Backward pass to compute gradients
output[:, pred_class].backward()

5. Compute the Heatmap

Using the captured gradients and activations, compute the Grad-CAM heatmap. The heatmap is calculated by weighting the activations by the average gradient and applying a ReLU activation to remove negative values. The heatmap highlights the regions in the image that are important for the prediction.

import numpy as np

# Compute the weights
weights = torch.mean(gradients[0], dim=[2, 3])

# Compute the Grad-CAM heatmap
heatmap = torch.sum(weights * activations[0], dim=1).squeeze()
heatmap = np.maximum(heatmap.cpu().detach().numpy(), 0)
heatmap /= np.max(heatmap)

6. Visualize the Heatmap

The final step is to overlay the computed heatmap on the original image. This visualization helps in understanding which regions of the image contributed most to the model’s decision.

import cv2

# Resize the heatmap to match the original image size
heatmap = cv2.resize(heatmap, (img.shape[1], img.shape[0]))

# Convert heatmap to RGB format and apply colormap
heatmap = cv2.applyColorMap(np.uint8(255 * heatmap), cv2.COLORMAP_JET)

# Overlay the heatmap on the original image
superimposed_img = cv2.addWeighted(img, 0.6, heatmap, 0.4, 0)

# Display the result
cv2.imshow('Grad-CAM', superimposed_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

By following these steps, you can effectively implement Grad-CAM in PyTorch to visualize and interpret the decision-making process of convolutional neural networks.

Grad-CAM is a powerful tool for visualizing and understanding the decisions of deep learning models. By providing insights into which parts of an image were most influential in a model’s prediction, Grad-CAM enhances model interpretability, trust, and transparency.

As a leading AI & ML software development company, CodeTrade leverages such advanced techniques to deliver robust and explainable AI solutions.

Effortless Object Detection In TensorFlow With Pre-Trained Models

CodeTrade India Pvt. Ltd. — Thu, 06 Jun 2024 10:56:44 +0000

Object detection is a crucial task in computer vision that involves identifying and locating objects within an image or a video stream. The implementation of object detection has become more accessible than ever before with advancements in deep learning libraries like TensorFlow.

In this blog post, we will walk through the process of performing object detection using a pre-trained model in TensorFlow, complete with code examples. Let’s start.

Steps to Build Object Detection Using Pre-Trained Models in TensorFlow

Before diving into the code, you must set up your environment and prepare your dataset. In this example, we’ll use a pre-trained model called ssd_mobilenet_v2_fpnlite_320x320_coco17_tpu-8 from TensorFlow’s model zoo, which is trained on the COCO dataset.

1. Data Preparation

First, let’s organize our data into the required directory structure:

import os
import shutil
import glob
import xml.etree.ElementTree as ET
import pandas as pd

# Create necessary directories
os.mkdir('data')

# Unzip your dataset into the 'data' directory
# My dataset is 'Fruit_dataset.zip'
# Replace the path with your dataset's actual path
!unzip /content/drive/MyDrive/Fruit_dataset.zip -d /content/data

# Move image and annotation files to their respective folders
# Adjust paths according to your dataset structure
# This code assumes that your dataset contains both 'jpg' and 'xml' files
# and organizes them into 'annotations_train', 'images_train', 'annotations_test', and 'images_test' folders.
# You may need to adapt this structure to your dataset.
# images & annotations for test data
for dir_name, _, filenames in os.walk('/content/data/test_zip/test'):
    for filename in filenames:
        if filename.endswith('xml'):
            destination_path = '/content/data/test_zip/test/annotations_test'
        elif filename.endswith('jpg'):
            destination_path = '/content/data/test_zip/test/images_test'
        source_path = os.path.join(dir_name, filename)
        try:
            shutil.move(source_path, destination_path)
        except:
            pass

# images & annotations for training data 
for dir_name, _, filenames in os.walk('/content/data/train_zip/train'):
    for filename in filenames:
        if filename.endswith('xml'):
            destination_path = '/content/data/train_zip/train/annotations_train'
        elif filename.endswith('jpg'):
            destination_path = '/content/data/train_zip/train/images_train'
        source_path = os.path.join(dir_name, filename)
        try:
            shutil.move(source_path, destination_path)
        except:
            pass

2. Convert XML Annotations to CSV

To train a model, we need to convert the XML annotation files into a CSV format that TensorFlow can use. We’ll create a function for this purpose:

import glob
import xml.etree.ElementTree as ET
import pandas as pd

def xml_to_csv(path):
    classes_names = []
    xml_list = []

    for xml_file in glob.glob(path + '/*.xml'):
        tree = ET.parse(xml_file)
        root = tree.getroot()
        for member in root.findall('object'):
            classes_names.append(member[0].text)
            value = (root.find('filename').text,
                     int(root.find('size')[0].text),
                     int(root.find('size')[1].text),
                     member[0].text,
                     int(member[4][0].text),
                     int(member[4][1].text),
                     int(member[4][2].text),
                     int(member[4][3].text))
            xml_list.append(value)
    column_name = ['filename', 'width', 'height', 'class', 'xmin', 'ymin', 'xmax', 'ymax']
    xml_df = pd.DataFrame(xml_list, columns=column_name)
    classes_names = list(set(classes_names))
    classes_names.sort()
    return xml_df, classes_names

# Convert XML annotations to CSV for both training and testing data
for label_path in ['/content/data/train_zip/train/annotations_train', '/content/data/test_zip/test/annotations_test']:
    xml_df, classes = xml_to_csv(label_path)
    xml_df.to_csv(f'{label_path}.csv', index=None)
    print(Successfully converted {label_path} xml to csv.')

This code outputs CSV files summarizing image annotations. Each file details the bounding boxes and corresponding class labels for all objects within an image.

3. Create TFRecord Files

The next step is to convert our data into TFRecords. This format is essential for training TensorFlow object detection models efficiently. We’ll utilize the generate_tfrecord.py script included in the TensorFlow Object Detection API.

#Usage:  
#!python generate_tfrecord.py output.csv output.pbtxt /path/to/images output.tfrecords

# For train.record
!python generate_tfrecord.py /content/data/train_zip/train/annotations_train.csv /content/label_map.pbtxt /content/data/train_zip/train/images_train/ train.record

# For test.record
!python generate_tfrecord.py /content/data/test_zip/test/annotations_test.csv /content/label_map.pbtxt /content/data/test_zip/test/images_test/ test.record

Ensure that you have a label_map.pbtxt file containing class labels and IDs in your working directory or adjust the path accordingly.

Complete Integration Guide for Redux State Management Library in Flutter

CodeTrade India Pvt. Ltd. — Mon, 27 May 2024 09:46:03 +0000

In the realm of mobile app development, managing the application state effectively is paramount. Flutter, a popular framework for building beautiful and performant cross-platform apps, offers built-in mechanisms for state management.

However, for complex applications with intricate state requirements that leverage a robust state management library like Redux can be highly beneficial.

Redux State Management Library

Redux is a predictable state container pattern. It enforces a unidirectional data flow for state updates, fostering predictability, testability, and scalability — especially advantageous for large-scale projects. While not originally designed for Flutter, Redux can be integrated with Flutter using third-party libraries.

Advantages of Redux State Management

Proven Track Record: Redux benefits from strong developer tooling and a large community inherited from the React ecosystem.
Unidirectional Data Flow: This ensures predictable and easily testable state updates.
Scalability: Redux is well-suited for complex applications with extensive state management needs.

How Redux Library Works in Flutter

Let’s embark on a step-by-step journey to integrate Redux into a simple Flutter app that manages a counter. This example will provide a clear understanding of core Redux concepts:

Step 1: Define an Enum for Actions in Redux

num Actions { Increment }

Step 2: Create a Counter Reducer Function

int counterReducer(int state, dynamic action) {
  if (action == Actions.Increment) {
    return state + 1;
  }
  return state;
}

The reducer function takes the current state and an action as arguments. It checks the action type and updates the state accordingly. Here, Increment increases the counter by 1.

Step 3: Setup the Redux Store

void main() {
  final store = Store<int>(counterReducer, initialState: 0);
  runApp(FlutterReduxApp(
    title: 'Flutter Redux Demo',
    store: store,
  ));
}

The Redux store serves as the central repository for your application’s state. It’s created using the Store class, which takes the counter reducer function and the initial state (0 in this case) as arguments. In our main function, we create the store and subsequently pass it to the FlutterReduxApp widget.

Step 4: Build the Flutter Redux App with StoreProvider

class FlutterReduxApp extends StatelessWidget {
   final Store<int> store;
   final String title;

   FlutterReduxApp({
     Key? key,
     required this.store,
     required this.title,
   }) : super(key: key);

   @override
   Widget build(BuildContext context) {
     return StoreProvider<int>(
       store: store,
       child: MaterialApp(
         theme: ThemeData.dark(),
         title: title,
         home: Scaffold(
           appBar: AppBar(
             title: Text(title),
           ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               StoreConnector<int, String>(
                  converter: (store) => store.state.toString(),
                  builder: (context, count) {
                     return Text(
                      'The button has been pushed this many times: $count',
                       style: Theme.of(context).textTheme.headline4,
                     );
                   },
                 )
               ],
             ),
            ),
            floatingActionButton: StoreConnector<int, VoidCallback>(
              converter: (store) {
                return () => store.dispatch(Actions.Increment);
            },
            builder: (context, callback) {
              return FloatingActionButton(
                 onPressed: callback,
                 tooltip: 'Increment',
                 child: Icon(Icons.add),
              );
           },
         ),
       ),
     ),
   );
 }
}

The StoreProvider widget is essential for making the Redux store accessible to descendant widgets throughout your application tree. It wraps the child widget (MaterialApp in this case) and provides the store instance to the context.

With these simple steps, you can easily integrate Redux state management into your Flutter app and leverage its benefits for managing complex application states.

Remember, this is a simplified example. For real-world applications, you’ll likely have multiple reducers, actions, and a more intricate state structure.

Riverpod State Management Package in Flutter 3.19

CodeTrade India Pvt. Ltd. — Fri, 03 May 2024 11:55:46 +0000

In the dynamic world of mobile app development, efficiency and scalability are paramount, especially when dealing with large-scale applications.

Flutter manages the complexity of mobile app development by providing cross-platform functionality.

The latest version of Flutter, 3.19, brings new features to make the development experience easier and more user-friendly. One of the best features that Flutter provides is State Management.

State Management

State management in Flutter acts as an app memory that stores crucial information like login status, user preferences, and more. It allows you to centrally manage this data and ensure it flows seamlessly throughout your app.

This is what empowers your app to adapt to user interactions and deliver a consistently delightful user experience. Flutter offers various state management packages to handle the state of your widgets. Let's explore the Riverpod State Management package for Flutter 3.19.

Riverpod State Management Package

A relatively new library inspired by Provider, Riverpod offers a simplified approach with a single source of truth for state management. It utilizes Providers to manage state and avoids boilerplate code with features like automatic provider scoping and change detection.

Advantages of Riverpod State Management Library

Easy to learn and use, with a clean and concise API.
Improves code organization and reduces boilerplate compared to Provider.
Automatic change detection ensures efficient UI updates.
Well-suited for both small and large applications.

Disadvantages of Riverpod State Management Library

Under development state with a smaller community compared to Provider.
Lack of some features available in other solutions.

How Riverpod Library Works

Let’s discuss the working process of Riverpod with an example:

Step 1. Define network requests by writing a function annotated with @riverpod:

@riverpod
Future<String> movieSuggestion(MovieSuggestionRef ref) async {
  final response = await http.get(
      Uri.https('https://xyz.com/api/movie'),
  );
  final json = jsonDecode(response.body);
  return json['activity']! as String;
}

Step 2. Listen to the network request in your UI and gracefully handle loading/error states.

class Home extends ConsumerWidget {
   @override
   Widget build(BuildContext context, WidgetRef ref) {
      final movieSuggestion = ref.watch(MovieSuggestionProvider);
      return movieSuggestion.when(
         loading: () => Text('loading'),
         error: (error, stackTrace) => Text('error: $error'),
         data: (data) => Text(data),
      );
   }
}

Myth vs. Fact: A Common Misconceptions About AI

CodeTrade India Pvt. Ltd. — Wed, 01 May 2024 11:19:25 +0000

Artificial Intelligence is everywhere nowadays, from your favorite music streaming service recommending new tunes to the self-checkout lane at the grocery store.

But with all this innovation buzz, there is also a lot of confusion. Are robots about to steal our jobs? Let’s separate the facts from the fiction and debunk some of the most common myths about AI.

In this article, we explain 10+ Myths vs Facts about AI. Let’s start exploring them one by one.

10+ Myth vs. Fact about AI

Myth #1: AI Can Think, Feel, or Talk Like a Human

Fact: AI can process information and respond in intelligent ways, but it lacks the true understanding, emotions, and consciousness that define human beings.

AI excels at pattern recognition and can generate human-like text, but it doesn’t possess the ability to feel happy, or sad it truly understands the meaning behind words.

For example, Imagine a child learning a new language. They can memorize vocabulary and sentence structures, but they don’t necessarily grasp the nuances of sarcasm, humor, or cultural references. Similarly, AI can mimic human language, but it lacks the deeper understanding that comes with human experience.

Myth #2: AI Can Surpass Human Intelligence in All Areas

Fact: AI executes specific tasks including data analysis and pattern recognition. However, it can not match human creativity, problem-solving skills in complex situations, and social intelligence.

Myth #3: AI Will Create Job Losses and Widespread Unemployment

Fact: While AI automation may affect some jobs, it’s more likely to transform them. New opportunities will emerge that require collaboration between humans and AI.

Imagine a doctor using AI to analyze scans and identify potential problems, then using their expertise to diagnose and treat the patient. AI can be a powerful tool to augment human capabilities, not replace them.

Myth #4: AI is Only Useful in Tech Industries

Fact: AI makes new waves in healthcare, finance, education, and countless other fields. From diagnosing diseases to personalized learning experiences, AI finds new applications across the spectrum.

It is used to streamline logistics in manufacturing, optimize resource allocation in agriculture, and even personalize marketing campaigns.

Myth #5: AI Understands Content As Humans Do

Fact: AI systems can analyze vast amounts of data and identify patterns within text or images. However, AI doesn’t grasp language or concepts the way we do.

It can recognize patterns in words and translate languages, but it lacks the deep understanding of context and cultural references that come naturally to humans.

Myth #6: AI is only for use by technically skilled people

Fact: Users from any background can leverage the capabilities of AI without technical expertise, because AI tools are increasingly accessible, for example, the most popular AI tools ChatGPT & Gemini Bard.

Cloud-based AI platforms and pre-built AI models are making it easier for people with no technical background to leverage the power of AI.

Myth #7: AI is unbiased

Fact: Despite its reputation for impartiality, AI systems can inherit biases from the data used to train them.

It’s crucial to ensure diverse data sets and develop algorithms that mitigate bias to avoid unfair outcomes in areas like loan approvals or facial recognition software.

Myth #8: Only Big Companies Can Use AI

Fact: AI adoption is not limited to corporate giants, organizations of all sizes can harness its power to drive growth and efficiency.

Startups and small businesses can harness AI to drive innovation and competitiveness. You don’t need a high budget to get started with AI.

Myth #9: More Data Means Better AI

Fact: Quality, not quantity, of data, is paramount in AI development. Clean, diverse, and relevant data is essential for effective AI systems. A large dataset with errors or irrelevant information will not produce good results.

Myth #10: AI algorithms can magically make sense of any of your messy data.

Fact: AI is not a magic bullet. The quality of the data you feed is critical. Clean, and organized data is essential for effective AI implementation. AI is not “load and go,” and the data quality is more important than the algorithm.

Myth #11: AI is a silver bullet for all problems.

Fact: While AI has the potential to solve complex problems, it is not a one-size-fits-all solution. AI Implementation considers various factors, including data quality, ethical implications, and the specific needs of users.

Moreover, AI is just one tool, and it effectively depends on how it is integrated into broader systems and processes.

Myth #12: AI is a Mystery — We Don’t Understand How it Works

Fact: While the inner workings of complex AI systems can be intricate, the core concepts are quite understandable.

There are many resources available to learn about different AI techniques that make the underlying ideas more accessible than ever.

Myth #13: You need data scientists, machine learning experts, and huge budgets to use AI for the business.

Fact: Many tools are increasingly available to business users and don’t require Google-sized investments.

Wrapping Up

There are many myths and facts about AI, but we need to understand the concept of AI. AI is a powerful tool with the potential to improve our lives in countless ways. The key to developing and using AI responsibly is to ensure benefits all of humanity.
