dtreenetwork 1.2.1

A Layered Decision Tree Based Model for Classification tasks

TreeNet

TreeNet is a lightweight and customizable machine learning model designed for flexible experimentation with layered network structures. It provides simple training and prediction interfaces and is well-suited for rapid prototyping and educational purposes.

Installation

You can install the package directly from PyPI:

pip install treenet

Or install it from the source:

git clone https://github.com/zeshanalvi/treenet.git
cd treenet
pip install .

Usage

Here’s a quick example of how to use TreeNet:

import numpy as np, pandas as pd, random, string
from treenet import TreeNet

# Initialize the model
model = TreeNet(layer_count=3, breath_count=2)

# Sample training data
col_labels = [''.join(random.choices(string.ascii_uppercase, k=10)) for _ in range(20)] # labels of 20 columns
trainXnp = np.random.rand(100, 20)   # 100 samples, 20 features
trainX = pd.DataFrame(trainXnp, columns=col_labels) # Dataframe
trainY = np.random.randint(0, 8, size=(100,)) # Multiclass labels with 8 classes

# Train the model
model.train(trainX, trainY)

# Sample test data
testXnp = np.random.rand(10, 20) # 10 samples, 20 features
testX = pd.DataFrame(testXnp, columns=col_labels) # Dataframe

# Predict probabilities
probabilities = model.predict_prob(testX)
print("Probabilities:\n", probabilities)

# Predict labels
predictions = model.predict(testX)
print("Predictions:\n", predictions)

API Reference

TreeNet

__init__(self, layer_count=2, breath_count=1)

Initializes a new TreeNet model.

layer_count (int): Number of layers in the network (default: 2).

breath_count (int): Number of parallel branches per layer (default: 1).

train(self, trainX, trainY)

Trains the model on given data.

trainX (np.ndarray): Training features of shape (n_samples, n_features).

trainY (np.ndarray): Training labels of shape (n_samples, 1).

predict_prob(self, testX) -> np.ndarray

Returns the probability distribution over classes for input samples.

testX (np.ndarray): Test features of shape (n_samples, n_features).

Returns: np.ndarray of shape (n_samples, n_classes).

predict(self, testX) -> np.ndarray

Returns predicted class labels for input samples.

testX (np.ndarray): Test features of shape (n_samples, n_features).

Returns: np.ndarray of shape (n_samples, 1).
