# Create label dataset
y = np.array([[0],[1],[1],[0]])

# Define neural network model
class NeuralNet():
    def __init__(self):
        self.inputSize = 2
        self.outputSize = 1
        self.hiddenSize = 3

        self.W1 = np.random.randn(self.inputSize, self.hiddenSize)
        self.W2 = np.random.randn(self.hiddenSize, self.outputSize)

    def forward(self, X):
        self.z = np.dot(X, self.W1)
        self.z2 = self.sigmoid(self.z)
        self.z3 = np.dot(self.z2, self.W2)
        o = self.sigmoid(self.z3)
        return o

    def sigmoid(self, s):
        return 1 / (1 + np.exp(-s))

    def sigmoidPrime(self, s):
        return s * (1 - s)

    def backward(self, X, y, o):
        self.o_error = y - o
        self.o_delta = self.o_error * self.sigmoidPrime(o)

        self.z2_error = self.o_delta.dot(self.W2.T)
        self.z2_delta = self.z2_error * self.sigmoidPrime(self.z2)

        self.W1 += X.T.dot(self.z2_delta)
        self.W2 += self.z2.T.dot(self.o_delta)

    def train(self, X, y):
        o = self.forward(X)
        self.backward(X, y, o)

# Train the neural network
nn = NeuralNet()
for i in range(10000):
    nn.train(X, y)

# Use the trained neural network for prediction
input_data = np.array([[1,0.5]])
print(nn.forward(input_data))

Future Development Trends

Reinforcement Learning Explained: A Journey into AI

F2K2 Game — Mon, 12 Jun 2023 07:44:45 +0000

Reinforcement Learning, or RL, is a type of Machine Learning that revolves around an agent – this could be a robot, a game character, a piece of software – basically anything that can make decisions, and an environment in which it operates. The agent takes actions, and based on those actions, it either gets a reward or a penalty.

Think of it like training a dog. You give it a treat when it behaves well (that's the reward), and you might ignore it when it misbehaves (that's the penalty). Over time, the dog learns to behave well to get more treats. That's essentially how reinforcement learning works!

Reinforcement Learning has some impressive applications. Google's DeepMind used RL to train an AI named AlphaGo, which went on to defeat the world champion at the game of Go, a feat previously thought to be decades away. RL is also used in self-driving cars, robotic control systems, and even in recommendation systems like YouTube's own algorithm!

Now, let's break down how reinforcement learning works. First, we have the 'state' of the environment. This is the current situation the agent finds itself in. Next, the agent takes an 'action'. This changes the state of the environment. Then, based on the new state and the action it took, the agent gets a 'reward' or a 'penalty'.

The goal of the agent is to figure out what actions it should take in what states to maximize its rewards over time. This is often a trial and error process, but as the agent interacts with its environment more and more, it slowly starts to improve its behavior."

So, that's reinforcement learning in a nutshell. It's an exciting field with so many potential applications.

Introduction to Machine Learning in HTML5 Games

F2K2 Game — Sat, 10 Jun 2023 07:33:41 +0000

Machine Learning (ML) is a fascinating domain of Artificial Intelligence (AI) that provides systems the ability to learn and improve from experience without being explicitly programmed. When this technology is combined with HTML5 game development, the results can be astonishing. Today, we're going to delve into how machine learning can be applied in HTML5 games and demonstrate some examples with code.

What is Machine Learning?

Machine Learning enables computers to learn and make decisions from data. This concept is often used to develop models that can predict outcomes based on input data. In the gaming world, ML can be used to create smart opponents, customize player experiences, and even develop entirely new types of gameplay.

ML in HTML5 Games

HTML5 has emerged as a powerful platform for game development, due to its ease of use, compatibility with a wide range of devices, and robust set of features. Pairing ML with HTML5 games opens a world of possibilities. For example, ML can be used to train an AI to adapt to the player's skill level, creating a more engaging and challenging gaming experience.

A Simple Example: AI Paddle in a Pong Game

Let's imagine we're creating a simple Pong game, where the player's paddle is controlled by the mouse and the opponent's paddle is controlled by AI. We'll use TensorFlow.js, a powerful ML library for JavaScript, for the AI component.

Here's a simplified version of the code:

// Import TensorFlow.js
import * as tf from '@tensorflow/tfjs';

// Set up the canvas
let canvas = document.getElementById('pongCanvas');
let context = canvas.getContext('2d');

// Create the paddles and ball
let playerPaddle = new Paddle(/* parameters */);
let aiPaddle = new Paddle(/* parameters */);
let ball = new Ball(/* parameters */);

// Set up TensorFlow.js model
let model;
(async function() {
  model = await tf.loadLayersModel('path/to/model.json');
})();

// Game loop
function gameLoop() {
  // Move the player paddle
  playerPaddle.move(/* parameters */);

  // Move the AI paddle
  let prediction = model.predict(tf.tensor2d([ball.y, ball.velocityY], [1, 2]));
  prediction.data().then(data => aiPaddle.move(data[0]));

  // Move the ball
  ball.move(/* parameters */);

  // Draw everything
  context.clearRect(0, 0, canvas.width, canvas.height);
  playerPaddle.draw(context);
  aiPaddle.draw(context);
  ball.draw(context);

  requestAnimationFrame(gameLoop);
}
requestAnimationFrame(gameLoop);

In this example, we're using TensorFlow.js to load a model that predicts the best position for the AI paddle based on the current position and velocity of the ball. This model would have been trained beforehand, probably using a technique like reinforcement learning, where the model learns from playing many games and adjusting its strategy based on whether it won or lost.

Reinforcement Learning

Reinforcement Learning (RL) is a type of Machine Learning where an agent learns to make decisions by taking actions in an environment to achieve a goal. The agent is 'rewarded' or 'punished' with points for each action, encouraging the system to make better decisions over time.

For instance, in the Pong game, we could implement a system where the AI receives a point every time it hits the ball, and loses a point every time it misses. The AI would then 'learn' over time to move in such a way as to hit the ball more often.

Integrating machine learning into HTML5 games can bring a whole new level of interactivity and realism to the gaming experience. Whether it's creating a dynamic opponent in a Pong game or developing a whole new type of gameplay, the possibilities are virtually endless. As machine learning continues to advance, we can expect to see even more impressive applications in the world of HTML5 gaming.

Remember that machine learning often requires significant computational resources and can be complex to implement, but the result is well worth the effort. Don't be afraid to start small and work your way up. Happy coding!

Go Lang - GORM

F2K2 Game — Thu, 29 Apr 2021 08:46:23 +0000

Preface

In order to facilitate accurate troubleshooting, it is necessary to record the corresponding relationship between the current request information and the currently executed SQL information. The recorded SQL information includes:

The current time of SQL execution;

File address and line number for executing SQL;
The time it takes to execute SQL;
The number of rows affected by SQL execution;
SQL statement executed;

The database component is used GORM.

Ideas

Before executing SQL, set the start execution time (it will be used to calculate the execution time);
After executing SQL, first, get the context of the current request, why get the context, because you need to get the request information from the context, second, get the time before SQL execution, to calculate the execution time, third, Getting SQL execution information, and then set the data Tracein Tracea project link packet, it will be introduced later in the article;

Above the need to use GORM two knowledge points Callbacks and Context these two are GORM V2 only the need to import the package gorm.io/gorm.

Demo code

Context The transfer requires GORM V2 provided With Context() a method.

func (u *userRepo) getUserByID(ctx core.Context, id uint) (*user_model.UserDemo, error) {
 data := new(user_model.UserDemo)
 err := u.db.GetDbR().WithContext(ctx).First(data, id).Error
 if err != nil {
  return nil, errors.Wrap(err, "[user_demo] get user data err")
 }
 return data, nil
}

Write CallBacks plug-in code, written in GORM Plugin interface is very simple, you only need to implement two methods can be.

// Plugin GORM plugin interface
type Plugin interface {
 Name() string
 Initialize(*DB) error
}

Below is the plug-in code I wrote:

type TracePlugin struct{}

func (op *TracePlugin) Name() string {
 return "tracePlugin"
}

func (op *TracePlugin) Initialize(db *gorm.DB) (err error) {
 // Before starting
 _ = db.Callback().Create().Before("gorm:before_create").Register(callBackBeforeName, before)
 _ = db.Callback().Query().Before("gorm:query").Register(callBackBeforeName, before)
 _ = db.Callback().Delete().Before("gorm:before_delete").Register(callBackBeforeName, before)
 _ = db.Callback().Update().Before("gorm:setup_reflect_value").Register(callBackBeforeName, before)
 _ = db.Callback().Row().Before("gorm:row").Register(callBackBeforeName, before)
 _ = db.Callback().Raw().Before("gorm:raw").Register(callBackBeforeName, before)

 // after the end
 _ = db.Callback().Create().After("gorm:after_create").Register(callBackAfterName, after)
 _ = db.Callback().Query().After("gorm:after_query").Register(callBackAfterName, after)
 _ = db.Callback().Delete().After("gorm:after_delete").Register(callBackAfterName, after)
 _ = db.Callback().Update().After("gorm:after_update").Register(callBackAfterName, after)
 _ = db.Callback().Row().After("gorm:row").Register(callBackAfterName, after)
 _ = db.Callback().Raw().After("gorm:raw").Register(callBackAfterName, after)
 return
}

var _ gorm.Plugin = &TracePlugin{}

func before(db *gorm.DB) {
 db.InstanceSet(startTime, time.Now())
 return
}

func after(db *gorm.DB) {
 _ctx := db.Statement.Context
 ctx, ok := _ctx.(core.Context)
 if !ok {
  return
 }

 _ts, isExist := db.InstanceGet(startTime)
 if !isExist {
  return
 }

 ts, ok := _ts.(time.Time)
 if !ok {
  return
 }

 sql := db.Dialector.Explain(db.Statement.SQL.String(), db.Statement.Vars...)

 sqlInfo := new(trace.SQL)
 sqlInfo.Timestamp = time_parse.CSTLayoutString()
 sqlInfo.SQL = sql
 sqlInfo.Stack = utils.FileWithLineNum()
 sqlInfo.Rows = db.Statement.RowsAffected
 sqlInfo.CostSeconds = time.Since(ts).Seconds()
 ctx.Trace().AppendSQL(sqlInfo)

 return
}

Finally, use this plug-in when db is connected:

// Use plugin
db.Use(&TracePlugin{})

summary

It is written in trace part of the package, this package can record information (JSON format):

Support setting trace_id

Support setting request information

Support setting response information

Support setting third_party_requests to request information

Support setting debugs to print debugging information

Support setting sqls to execute SQL information

Can record cost_seconds execution time

The above code is in the go-gin-api project, address:

Redis Go language interacts with Redis database

F2K2 Game — Wed, 28 Apr 2021 02:43:40 +0000

Installation

go get github.com/gomodule/redigo/redis

After the installation is complete, you can create a go file yourself: test.go

The content is as follows:

package main

import "github.com/gomodule/redigo/redis"

func main(){
    conn, _ := redis.Dial("tcp", ":6379")
    defer conn.Close()
    conn.Do("set", "c1", "hello")
}

Then compile and run the file, and then if the value of the key "c1" is found in redis, the installation is successful.

Method of operation

Go Redis documentation:

 https://godoc.org/github.com/gomodule/redigo/redis

Connect to the database

Dial(network, address string) (conn, err)

example:

redis.Dial("tcp", ":6379")
Execute database operation commands
    Send(commandName string, args ...interface{} error
    Flush() error
    Receive() (reply interface{}, err error)

The Send function issues an instruction, Flush flushes the connected output buffer to the server, and Receive receives the data returned by the server

example:

conn.Send("SET", "foo", "bar")
conn.Send("GET", "foo")
conn.Flush() // send the buffer command to the server
conn.Receive() // Receive the data returned by the set request
v, err := conn.Receive() // Receive the data requested by get

Another command to perform database operations (commonly used)

Do(commandName string, args ...interface{}) (reply interface{}, err error)

Reply helper functions

Bool, Int, Bytes, map, String, Strings and Values functions convert the response to a specific type of value.

In order to conveniently include calls to connect the Do and Receive methods, these functions take a second parameter of type error. If the error is non-nil, the helper function returns an error. If the error is nil, the function converts the reply to the specified type:

exists, err := redis.Bool(c.Do("EXISTS", "foo"))
if err != nil {
    //Handle the error code
}
reflect.TypeOf(exists) //Print exists type

Scan function

func Scan(src [] interface {},dest ... interface {}) ([] interface {},error)

The Scan function copies from src to the value pointed to by dest.

The value of the Dest parameter must be an integer, floating-point number, boolean, string, []byte, interface{} or a slice of these types. Scan uses the standard strconv package to convert batch strings to numeric and boolean types.

example:

var value1 int
var value2 string
reply, err := redis.Values(c.Do("MGET", "key1", "key2"))
if err != nil {
    //Handle the error code
}
if _, err := redis.Scan(reply, &value1, &value2); err != nil {
    // Handling error codes
}

Combine with the project

Serialization and deserialization
Serialization (byteization)

var buffer bytes.Buffer // container
enc := gob.NewEncoder(buffer) // encoder
err := enc.Encode(dest) // Encoding

Deserialization (deserialization)

dec := gob.NewDecoder(bytes.NewReader(buffer.bytes())) // decoder
dec.Decode(src) // Decode
