Training Data Platform Buying Guide

Vision AI & Training Data

Vision AI is a discipline of Machine Learning focussing on unstructured data. It can easily be broken down into two parts:

• Model selection and hyperparameter tuning

• Training data

Previously, research has been focused on model selection and hyperparameter tuning, but increasingly Google, Tesla, Facebook, and other top AI companies have focused on realizing gains from training data.

Google estimates that 83% of models fail because of poor training data management, but there are also significant performance benefits from experimentation with training data, and great AI companies focus significant time on this experimentation. 

What is a training data platform?

A training data platform forms part of the modern MLOps stack. It should enable the team not only to scale their training data but also to run experiments on that data to realize efficiency gains. 

The process of annotating data is the core functionality of a training data platform, but good training data platforms allow for rigorous QA processes and provide a dataset management module that can allow users to realize, and explain, gains provided by better training data utilization.

A training data platform should not be expected to provide new raw data or full end-to-end production AI. It is part of a broader machine learning stack, including raw data capture, training environments, hyperparameter tuning modules, and production hardware. As such, good training data platforms should have a flexible, open API to allow for easy integration into broader stacks.

Preparing your organization for a training data platform evaluation

Stakeholders

A rigorous training data platform evaluation should consider the concerns of four key stakeholder groups

1. Your Annotation workforce

2. Your Annotator Management team (sometimes can also be part of point 3)

3. Your data science/computer vision engineering team

4. Executive stakeholders

Before beginning an evaluation of training data platform providers, consult each of these groups. Find out what they need from a tool, what they want from a tool, and what they can’t do with the current system (or anything in particular they dislike about this). 

Typical priorities and roles in the evaluation process for these groups can be broken down in the table on the next page (which is by no means exhaustive).

Benchmarks

For any software purchasing decision, there will be qualitative factors (e.g. quality of support, UI), but anything that can be measured should be, both against the status quo and against other players in the evaluation

A good approach is to pick a limited number of projects to test and to evaluate those against key measurable criteria

1. Speed of annotation

2. Accuracy of annotation

3. Speed of administration

4. End-to-end project time

These projects should be varied across annotation and data types (i.e. if you’re doing semantic segmentation of MRIs, and classification of x-rays, test both projects on the platform). You should gather the existing benchmarks across these areas.
