Streamlined Inference: Deja Vu, a method that boosts LLM speed by activating only essential neural parts
It’s not necessary to activate all parts of a large language model to process a given input. Using only the necessary parts saves processing.

Better, Faster Network Pruning: Researchers devise pruning method that boosts AI speed
Pruning weights from a neural network makes it smaller and faster, but it can take a lot of computation to choose weights that can be removed without degrading the network’s performance.

Early Detection for Pancreatic Cancer: A neural network shows remarkable accuracy in forecasting risk of pancreatic cancer.
A neural network detected early signs of pancreatic cancer more effectively than doctors who used the usual risk-assessment criteria. Researchers at MIT and oncologists at Beth Israel Medical Center in Boston...

Sing a Tune, Generate an Accompaniment: SingSong, a tool that generates instrumental music for unaccompanied input vocals
A neural network makes music for unaccompanied vocal tracks. Chris Donahue, Antoine Caillon, Adam Roberts, and colleagues at Google proposed SingSong, a system that generates musical accompaniments for sung melodies. You can listen to its output here.

Deep Learning Discovers Antibiotics: Researchers used neural networks to find a new class of antibiotics.
Biologists used neural networks to find a new class of antibiotics. Researchers at MIT and Harvard trained models to screen chemical compounds for those that kill methicillin-resistant Staphylococcus aureus (MRSA), the deadliest among bacteria that have...

Optimizer Without Hyperparameters: VeLO, the system that eliminates the need for optimizer hyperparameters
During training, a neural network usually updates its weights according to an optimizer that’s tuned using hand-picked hyperparameters. New work eliminates the need for optimizer hyperparameters.

Neural Networks: Find the Function — A Basic Introduction to Neural Networks
Let’s get this out of the way: A brain is not a cluster of graphics processing units, and if it were, it would run software far more complex than the typical artificial neural network. Yet neural networks were inspired by the brain’s architecture.

Logistic Regression: Follow the Curve — A Basic Introduction to Logistic Regression for Machine Learning
There was a moment when logistic regression was used to classify just one thing: If you drink a vial of poison, are you likely to be labeled “living” or “deceased”? Times have changed.
