SVDClassifier 0.1.1

The SVD Classifier Package

SVDClassifier

This package provides the implementation for the SVD-based classifier developed in the Autonomous Agent Learning Lab at Connecticut College. This classifier is designed to be used with Evolutionary Strategies such as CMA-ES, Open-ES, and others due to it's reduced number of weights compared to a traditional convolutional neural network.

Installation

To install SVDC, use pip:

pip install SVDClassifier

Usage Example

The following is a simple example of using the SVDC classifier on a toy input:

from  SVDC.SVDC  import  SVDC
import  numpy  as  np
# Example weight vector, if the length is wrong the correct length will be returned as an error
weights = [0.1] * 111
# Example 5x5 input
sensor_input_sample = np.random.rand(5, 5)
# Create the SVDC Classifier, weight sizes are calculated for you based on the input sample
model = SVDC(weights, output_size=4, layer_count=1, sensor_input_sample=sensor_input_sample)
# Run forward pass on example input
output = model.forward(sensor_input_sample)
print("Output:", output)

The SVDC classifier can be optimized with CMA-ES by the following:

from SVDC.SVDC_CMA import SVDC_CMA
# Define fitnesss function
def fit_func(): ...
# Define the optimizer
optimizer = SVDC_CMA(
    starting_weights=starting_weights,
    output_size=desired_output_size,
    SVDC_layers=number_of_layers,
    fitness_function=fit_func,
    generations=total_generations_count,
    log_folder=folder_for_logs,
)
# Then run the optmizer and save the best result
result = optimizer.train(sample_input)
