Outline: this article discusses the issue of label uncertainty in supervised machine learning, highlighting limitations of majority voting. Next, it discusses the Bayesian mixture model to handle the uncertainty in labels. Full post

Outline: uncertainty quantification (UQ) is paramount in deploying machine learning models for safety-critical tasks. Among other shortcomings, many UQ methods rely on strict, hard-to-test, distributional assumptions. Conformal prediction provides a distribution-free alternative and has become a standard tool in the UQ shed. Full post

Outline: this article explains why correlation does not imply causation, using the example of chocolate consumption and intelligence. It further illustrates how confounding variables can lead to correlation and discusses statistical methods such as the instrumental variable approach to determine actual causal links. Full post

Outline: image segmentation is a prominent application of deep learning, but conventionally trained segmentation networks tend to make topological errors. Topological loss functions address this problem. But what does topological correctness mean? This post explains the basics of persistent homology, and how it can be used for machine learning.

Outline: a concise introduction to differential privacy which offers provably privacy guarantees for training machine learning models. Full post

Outline: adapting a deep neural network to unseen data and tasks is imperative these days, however access to target data is often available. Common target adaptation techniques including domain adaptation and generalization train for meaningful representations during source training. Recent paradigms such as Test-time training/adaptation focus on optimizing the source model on unseen data. To do so, they finetune the model on the streaming unsupervised data which is useful for practical scenarios. Moreover, these techniques can be applied to variety of tasks such as regression, classification and segmentation. Full post

Outline: uncertainty Quantification (UQ) is considered indispensable for predictive models in safety-critical applications. Modern models, though high-performing, struggle with providing meaningful uncertainty estimates due to a number of reasons. Full post
