Gradient-Based Learning

A comprehensive Python library for gradient-based learning, including neural networks, logistic regression, support vector machines (SVM), and more.

Introduction

The Gradient-Based Learning Library is a versatile toolset for implementing and experimenting with various machine learning algorithms that rely on gradient descent optimization. From basic linear regression to complex neural networks, this library provides a unified interface for building, training, and evaluating models.

Features

• Implementation of the Variable class for automatic differentiation
• Support for various activation functions and cost functions
• Modular neural network architecture with customizable layers and activations
• Logistic regression and support vector machine (SVM) implementations
• Optimizers including stochastic gradient descent (SGD) and batch gradient descent
• Extensible and easy-to-use API for adding custom models and functionalities

Installation

Install the library using pip:

pip install gradientblueprint

Usage

To use the library, import the necessary modules and classes into your Python code:

from gradientblueprint import Variable, MLP, LogisticRegression, SVM, Optimizer, CostFunction

Then, create instances of the provided classes and customize them according to your requirements. Here's a basic example of building and training a neural network:

# Define input dimension and layer dimensions
input_dim = 10
layer_dims = [32, 16, 8]

# Create a multilayer perceptron (MLP)
mlp = MLP(input_dim=input_dim, layers_dim=layer_dims, activations=['relu', 'relu', 'sigmoid'])

# Define optimizer and cost function
optimizer = Optimizer()
cost_function = CostFunction.mean_squared_error

# Train the MLP
for epoch in range(num_epochs):
    # Perform forward pass
    # Perform backward pass and update weights using optimizer

Refer to the documentation and examples for detailed usage instructions and customization options.
