The CatBoost paper has a nice example on overfitting of target encoding when not using cross-validation, this should be covered in the lecture slides.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The distribution of memories across hippocampal-cortical networks is a hallmark of memory consolidation. While repeated study has been shown to improve retention, the mechanisms supporting these ...

In the development of particle physics, researchers have introduced an innovative particle encoding mechanism that promises to improve how information in particle physics is digitally registered and ...

When I run this example, the differential impedance value seems OK and the smith chart seems reasonable. It's roughly matching the results from the coupled microstrip line impedance calculator in ...

What we see is not simply just a neural representation of the pattern of light in the eye, but an interpretation of this image, to which our needs and expectations contribute. These factors are shaped ...

Summary: Arousal levels directly influence how the brain processes visual information. Researchers found that the firing patterns of neurons in the thalamus, a key relay station for visual signals, ...
