Capstone Step 12: Share Your Project with the World

Introduction

For my capstone project, I developed data collection and model testing framework applications designed to facilitate dataset acquisition, processing, and Automatic Speech Recognition (ASR) model evaluation for machine learning practitioners and developers. This framework addresses the challenges of testing machine learning audio transcription models across diverse datasets and configurations, providing a standardized environment for evaluation and comparison.

GitHub Repository

The complete code for the project, including model development and deployment, is available on GitHub:

https://github.com/brettdavies/yt_dlp_async
https://github.com/brettdavies/whisper_chunk_transcribe

This repository contains:

  • Code for Data Collection and Preprocessing: Scripts and modules used to acquire and preprocess datasets from various sources.
  • Model Testing Framework Source Code: The core application code is organized into modular components.
  • Installation Instructions and Documentation: Detailed guides on how to install, configure, and use the framework.
  • Examples and Tutorials: Example projects demonstrating how to utilize the framework effectively.
  • CI/CD Pipeline Configuration: Files related to continuous integration and deployment processes.

Application Interface

An interactive interface for the Model Testing Framework is accessible via a highly configurable command line interface.

This interface allows users to:

  • Acquire Datasets: Retrieve data from APIs, databases, or local files using the data acquisition module.
  • Process Data: Clean, normalize, and transform data using the data processing module.
  • Evaluate Models: Test machine learning models with standardized metrics through the model evaluation module.
  • Monitor Performance: Access real-time metrics and logs via integrated monitoring tools.

Note: The application interface is accessible locally when the Docker container is running. Instructions on how to set up and run the application are provided in the GitHub repository.

Project Overview

Problem Statement

Machine learning practitioners often face challenges in testing and evaluating audio transcription models across different datasets and environments. These challenges include:

  • Data Heterogeneity: Handling diverse data formats and sources.
  • Environment Consistency: Ensuring that models are evaluated consistently across different systems.
  • Scalability: Managing resource constraints when dealing with large datasets or complex models.
  • Usability: Providing accessible tools for users with varying levels of technical expertise.

Approach

The Model Testing Framework aims to address these challenges by providing a comprehensive solution that is:

  • Modular: Separating functionalities into distinct, reusable components.
  • Scalable: Utilizing containerization to manage resources efficiently.
  • User-Friendly: Offering common interfaces across multiple deployment types to cater to different user environments.
  • Extensible: Allowing users to integrate custom modules and extend the framework’s capabilities.
