Introduction

This ML Platform provides a robust framework to streamline machine learning workflows, from data preprocessing and model training to evaluation and deployment. It offers a simple interface for running experiments and managing models. The platform also provides scalability for production use with integration tools for popular cloud services.

Installation

Prerequisites

Before setting up the platform, ensure you have the following:

• Python 3.8+: The platform requires Python version 3.8 or above. You can download it from here.
• Git: Git is used for version control. Install Git from here.
• Package Manager: Preferably pip for installing dependencies.

Setup

1. Clone the Repository:

   git clone https://github.com/yourusername/ml-platform.git
   cd ml-platform

2. Create and Activate a Virtual Environment (optional but recommended):

   python3 -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

3. Install Dependencies:

   Install all required packages listed in the requirements.txt file.

   pip install -r requirements.txt

   Alternatively, you can use conda if you prefer:

   conda env create -f environment.yml

4. Install Jupyter Notebook (optional):

   If you intend to run notebooks as part of your workflow, install Jupyter:

   pip install jupyterlab

Platform Structure

Directory Structure

The platform follows a modular structure. Below is an overview of the directory and file layout:

Modules

• Data Preprocessing (data_preprocessing.py): Contains functions for cleaning, transforming, and normalizing the input data.
• Feature Engineering (feature_engineering.py): Provides functions for creating new features, selecting features, and encoding categorical variables.
• Model (model.py): Includes functions for training models, cross-validation, hyperparameter tuning, and evaluation metrics.
• Deployment (deployment.py): Contains functions for deploying trained models to production, including saving models and generating predictions.

Usage

Training

To train a model, follow these steps:

1. Prepare Data: Ensure that the data is placed in the correct directories (data/raw/ for raw data).

2. Preprocess Data: Execute the data preprocessing script:

   python scripts/preprocess_data.py

   This will clean and preprocess the data and save it in data/processed/.

3. Train Model: Train the model using the training script:

   python scripts/train_model.py

   This will:

   • Load the preprocessed data
   • Split the data into training and validation sets
   • Train the model using a specified algorithm (e.g., Random Forest, XGBoost, or Neural Networks)
   • Save the trained model in the models/ directory

4. View Training Output: The script will output training metrics such as accuracy, precision, recall, and loss.

Model Evaluation

To evaluate the trained model:

1. Evaluate Model: Run the model evaluation script:

   python scripts/test_model.py

   This will:

   • Load the trained model
   • Evaluate it on the test data
   • Output various evaluation metrics (e.g., confusion matrix, ROC-AUC score, etc.)

Deployment

To deploy the trained model into a production environment, follow these steps:

1. Save Model: After training, save the model using the deployment script:

   python scripts/deployment.py --save_model

2. Deploy Model: Once saved, the model can be deployed using any deployment method (e.g., cloud service, REST API). You can integrate with frameworks such as Flask, FastAPI, or Django.

Configuration

Configuration settings for the platform (e.g., dataset paths, model parameters, training options) are managed in the config/config.yaml file.

Example Configuration

data:
  input_path: "data/raw/dataset.csv"
  output_path: "data/processed/processed_dataset.csv"

model:
  type: "RandomForestClassifier"
  hyperparameters:
    n_estimators: 100
    max_depth: 5
    random_state: 42

training:
  batch_size: 32
  epochs: 50

How to Modify Configuration

You can modify the configuration file to change parameters like:

• Model type (e.g., RandomForest, SVM, Neural Network)
• Hyperparameters (e.g., n_estimators, learning_rate)
• Paths to data and output directories
