What are training data platforms?

Training data platforms are software that automates the following processes for companies:

• Labels Data: Training supervised ML models requires processes such as image, text, and audio annotations. Training data platforms provide automated labeling for enterprises.
• Diagnostics: Training data platforms identify model errors and understand performance trends that help the IT team monitor models.
• Prioritize: It is not optimal for organizations to spend time on labeling poor quality data. Training data platforms determine the most effective use of data.

Why are training data platforms important?

McKinsey argues that data-related issues are the biggest struggle in developing effective ML models. In this regard, training data platforms that provide solutions for reaching high-quality data directly impact the competitiveness of companies.
