Machine Learning Regression Techniques

Linear Regression for Transmission Quality

Linear regression is one of the simplest and most widely used ML regression techniques. It models the relationship between a dependent variable and one or more independent variables by fitting a linear equation to the observed data. In the context of lightpath transmission quality, linear regression can be used to predict quality metrics such as SNR or BER based on factors like signal power, distance, and network load.

Linear regression is easy to implement and interpret, making it a good starting point for transmission quality estimation. However, it assumes a linear relationship between the variables, which may not always hold in complex optical networks. Despite this limitation, linear regression can provide valuable insights and serve as a benchmark for more advanced models.

Can Machine Learning Accurately Predict Continuous Variables?

Here’s an example of using linear regression for predicting SNR with Scikit-learn:

import numpy as np
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
from sklearn.metrics import mean_squared_error

# Sample data
data = {
    'signal_power': [10, 20, 30, 40, 50],
    'distance': [1, 2, 3, 4, 5],
    'network_load': [0.5, 0.6, 0.7, 0.8, 0.9],
    'snr': [15, 18, 21, 24, 27]
}
df = pd.DataFrame(data)

# Features and target variable
X = df[['signal_power', 'distance', 'network_load']]
y = df['snr']

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Train a linear regression model
model = LinearRegression()
model.fit(X_train, y_train)

# Predict on test data
y_pred = model.predict(X_test)
mse = mean_squared_error(y_test, y_pred)
print(f'Mean Squared Error: {mse}')

Polynomial Regression for Non-Linear Relationships

Polynomial regression extends linear regression by fitting a polynomial equation to the data, allowing for modeling non-linear relationships between the variables. This technique can capture more complex patterns in the data, making it suitable for estimating lightpath transmission quality in scenarios where the relationship between factors is non-linear.

In polynomial regression, the input variables are transformed into polynomial features of a specified degree. The model then fits a linear equation to these transformed features. By choosing an appropriate degree for the polynomial, the model can capture the underlying non-linear relationships and provide more accurate predictions.

While polynomial regression can improve prediction accuracy, it also increases the risk of overfitting, especially with higher-degree polynomials. Regularization techniques such as ridge regression can be used to mitigate overfitting and enhance model generalization.

from sklearn.linear_model import LinearRegression
from sklearn.metrics import mean_squared_error

# Sample data
data = {
    'signal_power': [10, 20, 30, 40, 50],
    'distance': [1, 2, 3, 4, 5],
    'network_load': [0.5, 0.6, 0.7, 0.8, 0.9],
    'ber': [0.01, 0.015, 0.02, 0.025, 0.03]
}
df = pd.DataFrame(data)

# Features and target variable
X = df[['signal_power', 'distance', 'network_load']]
y = df['ber']

# Transform features to polynomial features
poly = PolynomialFeatures(degree=2)
X_poly = poly.fit_transform(X)

# Split data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X_poly, y, test_size=0.2, random_state=42)

# Train a polynomial regression model
model = LinearRegression()
model.fit(X_train, y_train)

# Predict on test data
y_pred = model.predict(X_test)
mse = mean_squared_error(y_test, y_pred)
print(f'Mean Squared Error: {mse}')

Random Forest Regression for Complex Patterns

Random Forest regression is an ensemble learning method that combines multiple decision trees to improve predictive accuracy and robustness. Each decision tree in the forest is trained on a random subset of the data and features, and the final prediction is obtained by averaging the predictions of all the trees.

Random Forest regression is particularly effective for estimating lightpath transmission quality in complex and heterogeneous environments. It can handle non-linear relationships, interactions between variables, and the presence of noise in the data. Additionally, Random Forests provide feature importance measures, helping to identify the most influential factors affecting transmission quality.

Despite its advantages, Random Forest regression can be computationally intensive, especially with large datasets and many trees. However, its ability to capture complex patterns and provide accurate predictions makes it a valuable tool for transmission quality estimation.
