matplotlab 0.1.4

Extended plotting and ML utilities library

Matplotlab

Extended plotting and machine learning utilities library for educational purposes.

A comprehensive Python library providing:

• Reinforcement Learning (RL) - Monte Carlo, TD Learning, Policy/Value Iteration, Dynamic Programming
• Artificial Neural Networks (ANN) - Deep Learning implementations with PyTorch and TensorFlow
• Visualization Tools - Enhanced plotting capabilities for ML workflows

Installation

# Install from PyPI
pip install matplotlab

# Or install from source
git clone https://github.com/Sohail-Creates/matplotlab.git
cd matplotlab
pip install -e .

Quick Start

Reinforcement Learning

from matplotlab import rl

# Create environment and find optimal policy
env = rl.create_frozenlake_env()
policy, V, iterations = rl.policy_iteration(env, gamma=0.99)
print(f"Converged in {iterations} iterations")

# Visualize results
rl.plot_value_heatmap(V)
rl.plot_grid_policy(policy)

# NEW: See complete lab workflow (Lab 1-6 + OEL)
rl.flowlab3()  # Shows complete Lab 3 code from import to visualization
rl.flowlab5()  # Shows complete Lab 5 (Policy Iteration) workflow

Artificial Neural Networks

from matplotlab import ann
import torch.nn as nn

# Create simple MLP model
model = ann.create_mlp_model(input_size=10, hidden_sizes=[16, 8], output_size=1)

# Or create CNN
cnn_model = ann.create_fashion_cnn()

# Training is straightforward
for epoch in range(50):
    y_pred = model(X_train)
    loss = loss_fn(y_pred, y_train)
    optimizer.zero_grad()
    loss.backward()
    optimizer.step()
