fastML Downloads

A Python package built with sklearn for running multiple classification algorithms in as little as 4 lines. This package drastically makes the work of Data Scientists, AI and ML engineers very easy and fast by saving them the physical stress of writing close to 200 lines of code as they would if not for this package.

Algorithms

  • Logistic Regression

  • Support Vector Machine

  • Decision Tree Classifier

  • Random Forest Classifier

  • K-Nearest Neighbors

  • NeuralNet Classifier

Getting started

Install the package

pip install fastML

Navigate to folder and install requirements:

pip install -r requirements.txt

Usage

Assign the variables X and Y to the desired columns and assign the variable size to the desired test_size.

X = < df.features >
Y = < df.target >
size = < test_size >

Encoding Categorical Data

Encode target variable if non-numerical:

from fastML import EncodeCategorical
Y = EncodeCategorical(Y)

Using the Neural Net Classifier

from nnclassifier import neuralnet

Running fastML

fastML(X, Y, size, RandonForestClassifier(), DecisionTreeClassifier(), KNeighborsClassifier(), SVC(),
        include_special_classifier = True, # to include the neural net classifier
        special_classifier_epochs=200,
        special_classifier_nature ='fixed'
)

You may also check the test.py file to see the use case.

Example output

Using TensorFlow backend.
