Point process models for sequence detection in high-dimensional neural spike trains
arXiv.org 80d 2 tweets
Sparse sequences of neural spikes are posited to underlie aspects of working memory, motor production, and learning. Discovering these sequences in an unsupervised manner is a longstanding problem in statistical neuroscience. Promising recent work...

Identifying Learning Rules From Neural Network Observables

The brain modifies its synaptic strengths during learning in order to better adapt to its environment. However, the underlying plasticity rules that govern learning are unknown. Many proposals have been suggested, including Hebbian mechanisms,...

Dynamic and reversible remapping of network representations in an unchanging environment
bioRxiv 100d 5 tweets
In response to environmental changes, the medial entorhinal cortex alters its single-cell firing properties. This flexibility in neural coding is hypothesized to support navigation and memory by dividing sensory experience into unique contextual...

Alex Williams🌹 Lots of other details in the preprint - e.g running speed correlates with these remap events. Overall, we think this points to greater network-level dynamism & flexibility in cortex than we expected. Large-scale recordings absolutely essential to see this 99d

Surprises in High-Dimensional Ridgeless Least Squares Interpolation
arXiv.org 662d 2 tweets
Interpolators -- estimators that achieve zero training error -- have attracted growing attention in machine learning, mainly because state-of-the art neural networks appear to be models of this type. In this paper, we study minimum $\ell_2$-norm...
