Introduction:
In today’s world, data processing and communication technologies are becoming increasingly important. With the widespread use of the Internet, computing systems like the client-server model are commonly used for data transmission and processing. In this article, we will focus on data transmission and machine learning using a client-server model.
Learning Objectives:
- Understanding how the client-server model works.
- Understanding how data transmission and processing are performed.
- Learning how a machine learning model is trained and evaluated.
- Developing coding skills and being able to use these skills in real-world applications.
What is Machine Learning?
Machine learning is a branch of artificial intelligence where computer systems are trained to recognize patterns, learn, and make predictions based on data. This process allows algorithms to improve themselves to achieve a certain task at a certain level of performance using data.
Types of Machine Learning:
- Supervised Learning: Supervised learning focuses on modeling the relationship between input and output in a sample dataset. In this type of learning, the algorithm creates a prediction model using the data and then makes predictions with this model using new inputs.
- Unsupervised Learning: Unsupervised learning is used to describe the structure of the data and is often used to uncover hidden structures in data. Techniques such as clustering and dimensionality reduction are examples of unsupervised learning.
- Reinforcement Learning: Reinforcement learning focuses on teaching an agent how to behave in a decision process with feedback from the environment on which action to take.
Client and Server Code Descriptions:
The client and server codes are written to create a client-server model. The client generates random data and sends it to the server. The server, in turn, trains a machine learning model using the received data. Here are detailed explanations of the codes:
- serverAI.py: The code on the server side ensures the server’s operation. This code creates a socket to receive data from the client. Then, it processes the received data to create a more complex target variable and trains a machine learning model using this data.
# First, we import necessary libraries
import socket
import pandas as pd
from sklearn.preprocessing import PolynomialFeatures
from sklearn.linear_model import LinearRegression
from sklearn.pipeline import make_pipeline
from sklearn.model_selection import train_test_split
from sklearn.metrics import mean_squared_error, r2_score
import time
# Define the address and port number for the server to run on:
host = '127.0.0.1'
port = 12345
# Next, we create a socket and start listening on the specified port
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind((host, port))
server_socket.listen(1)
# Print a message indicating that the server has started and is waiting for client connection
print("The server has been started. Waiting for client connection...")
# Accept the connection from the client and print the address of the connected client
client_socket, addr = server_socket.accept()
print(f"{addr} is connected.")
# Then, we create a loop to collect data from the client. We collect data for 60 seconds
data = []
try:
start_time = time.time()
while time.time() - start_time < 60: # Collect data for 1 minute
message = client_socket.recv(1024).decode()
if not message:
break
print(f"Received Data : {message}")
data.append(float(message))
finally:
client_socket.close()
server_socket.close()
# Convert the data to a DataFrame and create a more complex target variable
df = pd.DataFrame(data, columns=['feature'])
df['target'] = df['feature'] ** 2 + 5 * df['feature'] + 3 # Create a more complex target variable
# Finally, we perform data preprocessing and model training. These steps split the data into training and test sets and train a regression model with a polynomial degree of 2:
X_train, X_test, y_train, y_test = train_test_split(df[['feature']], df['target'], test_size=0.2, random_state=42)
model = make_pipeline(PolynomialFeatures(degree=2), LinearRegression())
model.fit(X_train, y_train)
# Test the model performance and print the results
predictions = model.predict(X_test)
mse = mean_squared_error(y_test, predictions)
r2 = r2_score(y_test, predictions)
print(f"Model MSE : {mse}")
print(f"Model R2 Score: {r2}")- clientAI.py: The code on the client side allows the client to send data to the server. This code generates a random number every 10 seconds and sends it to the server.
import socket
import time
import random
# Define the address and port number for the server
host = '127.0.0.1'
port = 12345
# Create a socket and connect to the server
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((host, port))
# Generate random data at specified intervals and send it to the server
try:
for _ in range(6): # Send data every 10 seconds for 1 minute
number = random.uniform(-10, 10) # Send a random number between -10 and 10
print(f"Sent data: {number}")
client_socket.sendall(str(number).encode())
time.sleep(10)
finally:
client_socket.close()
print("Data transfer completed.")These codes focus on data transmission and machine learning using the client-server model. The client generates random data and sends it to the server. The server, in turn, trains a machine learning model using the received data.(Project github link)
Data Transmission and Processing:
The data generated by the client is transmitted to the server over a socket. The server collects the received data and then trains a machine learning model using this data. The machine learning model is then used to understand the relationship between the data and make predictions for future data points.
Performance Evaluation and Results:
The performance of the machine learning model is evaluated using tests on training data. These tests measure the accuracy of the model, mean squared error (MSE), and R-squared score. Performance evaluation results help us understand how well the model is working and ensure the
