Title:  Active learning for industrial applications: training machine learning models with less data

Presenter: Davide Cacciarelli

Time: March 4, 2025, 16:00-17:00 CET / 10:00 AM EST / 7:00 AM PST

Abstract:  In this webinar, we will explore active learning-based sampling strategies and their potential applications to industrial data. Active learning is a valuable approach for streamlining the development of classification and regression models, particularly in environments where acquiring labelled data is both time-consuming and costly. By selecting the most informative data points to label, active learning enables high model performance with significantly reduced labelling efforts. We will begin with an overview of active learning, discussing key scenarios and query strategies. Following this, we will present a brief case study on the use of active learning to improve a defect detection classifier. The webinar will then shift focus to strategies for managing data streams, introducing stream-based active learning. We will cover techniques for training linear models, handling concept drift, and leveraging knowledge distillation for efficient model scaling. Join us to discover how active learning can enhance the development of machine learning models while minimising the need for expensive labelled data.
