Lévy walk patterns identified in nuclear particle collisions
Called the Lévy walk (or in some cases the Lévy flight) after mathematician Paul Lévy, it is a type of random wandering that ...
Grid cells' rhythmic sweeps reshape understanding of brain's spatial navigation
A discovery at the Kavli Institute at the Norwegian University of Science and Technology (NTNU) in Norway has uncovered a ...
Quantum effects make distant objects move together: new research finds this may happen with ripples in space
When two objects share a quantum state, their behaviour becomes mysteriously linked. If you measure one object, the state of ...
Dramatically decreasing the time it takes to measure asteroid distances
We all know that asteroids are out there, that some of them come dangerously close to Earth, and that they've struck Earth before with catastrophic consequences. The recent discovery of asteroid 2024 ...

On the Convergence of Decentralized Stochastic Gradient Descent With Biased Gradients
To address this issue, we perform a comprehensive convergence rate analysis of stochastic gradient descent (SGD) with biased gradients for decentralized optimization. In non-convex settings, we show ...
