OpenAL: Evaluation and Interpretation of Active Learning Strategies

We are pleased to present our work accepted at the NeurIPS 2022 Workshop on Human in the Loop Learning! For a complete overview of our work, we refer to our paper and the OpenAL GitHub repository. Despite being proven useful in practice, active learning (AL) suffers from two main drawbacks: …

Towards Efficient Labeling in Federated Learning

Federated Learning (FL) can enable privacy-preserving distributed computation across several clients. It is used to federate knowledge from parties that do not wish to share their data. For example, project MELLODDY has applied it to drug discovery by federating models from several private laboratories to share the learning effort. But…

Diversity in Outcome Optimization of ML Models

ML outcome optimization is the process of finding optimal feature values that give the model prediction minimum (or maximum) over a defined space. For black-box ML models, we cannot assume any of the usual smoothness properties for optimization, such as convexity or even differentiability. …

I Can’t Believe It’s Not Better — Active Learning Flavor

This is the story of a research project that didn’t quite make it. As every research project, it started with what seemed like a good and natural idea. As with most research projects, it didn’t end up as groundbreaking work. It wasn’t a catastrophic failure either. We believe that our…

A (Slightly) Better Budget Allocation for Hyperband

This blog post highlights a minor discrepancy in the Hyperband method. It does not question the validity of the method nor its results. The spotted deviation leads Hyperband to underuse its allocated budget, so this may result in faster computation but degraded performance. Edit: We received an answer from the…

Diverse Mini-Batch Active Learning: A Reproduction Exercise

In our previous blog post, A Proactive Look at Active Learning Packages, we gave an overview of the most basic methods of active learning together with the most common Python packages as well as the more advanced methods they implement. For this second post, we’ll have a look at more…

A Proactive Look at Active Learning Packages

If data acquisition is the very first step of any machine learning project, unfortunately, data doesn’t always come with the label of interest for the task at hand. It is often a very cumbersome task to (correctly!) label the data — and that’s where Active Learning comes in. Instead of…
