ML Helper

pub version license

ML Helper is a lightweight Dart library for machine learning. It provides tools for linear regression, metrics, and data preprocessing, fully offline and Flutter-friendly.

Features

  • 📈 Linear Regression: A simple and easy-to-use implementation of the linear regression algorithm.
  • 🧼 Preprocessing: Essential tools for preparing your data, including normalization and train/test split.
  • 📊 Metrics: Evaluate your model's performance with key metrics like accuracy, recall, f1-score, and Mean Squared Error (MSE).
  • 🔢 Math Utilities: A collection of helpful math functions such as mean, standard deviation, sigmoid, and softmax.
  • ⚡ Lightweight: Built with zero dependencies to keep your project lean.
  • 📱 Offline & Flutter-Friendly: Works seamlessly in your Dart and Flutter projects without needing an internet connection.

Getting Started

1. Installation

Add this to your package's pubspec.yaml file:

dependencies:
  ml_helper: ^0.0.1

Then, run flutter pub get in your terminal.

Usage

Import the package in the file where you want to use it:

import 'package:ml_helper/ml_helper.dart';

Here’s a quick example of how to use the LinearRegression model:

Code

void main() {
  // 1. Sample data
  final X = [[1.0], [2.0], [3.0], [4.0]];
  final y = [2.0, 4.0, 6.0, 8.0];

  // 2. Create and train the model
  final model = LinearRegression();
  model.fit(X, y);

  // 3. Make predictions
  final predictions = model.predict([[5.0], [6.0]]);

  // The model learned y = 2x, so it should predict [10.0, 12.0]
  print('Predictions: $predictions');
}
