Project Abstract

labellab

LabelLab is an image analysis and classification platform for machine learning (ML) researchers. Originally built to classify images of elephants, it has been developed over the years and is now a full-fledged ML utility tool that is able to classify all kinds of images and carry out a number of ML-related tasks in a project-based manner while teaming up with other researchers.

Work Summary

LabelLab mainly consists of 3 sections -

  1. Backend built using Flask
  2. Frontend built using React.js
  3. Mobile Application built using Flutter

Albeit a couple of features that were exclusive to the mobile application, most of my work across GSoC 2021 spanned across all 3 sections of the project.

Expanding Team Management

  • Now inside a project, the project admin can create multiple teams, each having a specific functionality, and add users to them.
  • These teams can later be updated or deleted by an admin.
  • These teams can only perform actions inside a project that are authorized by their role (role-based access control). E.g. - A models team member can only work with models inside that project.
  • The project owner can make other users admins for better project management. The admin priviledge can also be revoked by the owner when necessary.
  • Project structure was modified to accomodate multiple admins.
  • Admins form a superset of all other role and can perform any actions inside a project
  • Now, a member can also voluntarily leave a project. Earlier, they had to removed by the admin.

Implementing Project Activity Tracking

  • Created a Project Activity Tracking System which helps keep track of all changes inside a project such as -
    • Adding/removing members
    • Adding and labelling images
    • Creating labels
    • Creating and training models
    • and much more...
  • Each activity log is associated with a particular category (general, images, labels etc) and a particular user (the one who made that change).
  • These activity logs can be filtered for analysis of the progress of the project.
    • category-specific - View activity logs of a particular category.
    • member-specific - View activity logs of a particular project member.
    • team-specific - View activity logs of a particular team.
    • entity-specific - View changes made to a particular entity (image, label, model etc)

Creating a Backend Service Selection Utility

  • Created a backend service selection utility in the mobile application.
  • This allows the user to enter the URL of the LabelLab API instance that the application should use.
  • This provides the functionality to connect to multiple backend instances without much tinkering.

What left

I managed to complete all my milestons within the coding period, and also implemented a few additional features. But there are a few other features the project could benefit from such as -

  • Creating initialization scripts for the project
  • Writing unit tests for the backend
  • Fixing dependencey versions and warnings in the frontend
