The A-Z of Transformers: Everything You Need to Know

Everything you need to know about Transformers, and how to implement them — Why another tutorial on Transformers? You have probably already heard of Transformers, and everyone talks about it, so why making a new article about it? Well, I am a researcher, and this requires me to have a very deep understanding of the tools I use (because if you don’t understand them, how can you identify…

Entropy based Uncertainty Prediction

This article explores how Entropy can be employed as a tool for uncertainty estimation in image segmentation tasks. We will walk through what Entropy is, and how to implement it with Python. — While working at Cambridge University as a Research Scientist in Neuroimaging and AI, I faced the challenge of performing image segmentation on intricate brain datasets using the latest Deep Learning techniques, especially the nnU-Net. During this endeavor, I observed a significant gap: the overlooking of uncertainty estimation. Yet, uncertainty is…
