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,...
Sussillo, David | Universality and individuality in neural dynamics across large populations of recurrent networks
David Sussillo from Google Brain, adjunct professor at Stanford University, talks about universality and individuality in neural dynamics across large populations…

Really nice talk from @SussilloDavid on the philosophy & motivation behind comparing RNNs and biological networks at Bernstein conference, @NNCN_Germany. (Forgive the self-promotion by proxy.)

Herd Immunity? Or ‘Mass Murder’?
A proposal to let people with low risk of infection live without constraint could lead to a million or more preventable deaths.
Dynamic and reversible remapping of network representations in an unchanging environment
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...

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

@IgorCarron @ravinaproject You're correct. Confusion might be that there was a Paris commune during the Revolution (en.wikipedia.org/wiki/Paris_Com…) not to be confused with the commune of 1871 (en.wikipedia.org/wiki/Paris_Com…)

UC Santa Cruz Reinstates 41 Graduate Students After Months-Long Strike
The strike for a cost of living adjustment earlier this year galvanized students at nearly every single campus in the University of California’s 285,000-student system.Â
College Democrat at Center of Attack on Alex Morse Hoped to Launch Career Through Richard Neal
Rank-and-file UMass College Democrats were stunned to see the letter their chapter’s leadership wrote on their behalf.
Surprises in High-Dimensional Ridgeless Least Squares Interpolation
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...

The generalization error of random features regression: Precise asymptotics and double descent curve
Deep learning methods operate in regimes that defy the traditional
statistical mindset. The neural network architectures often contain more
parameters than training samples, and are so rich that they can interpolate the
observed labels, even if the...

Biden: We must urgently root out systemic racism, from policing to housing to opportunity
Federal dollars should not go to departments that violate people’s rights or turn to violence as a first resort, Joe Biden says in an USA TODAY op-ed.
Pelosi, top Democrats unveil police reform bill
The measure would ban chokeholds like the kind that led to the death of George Floyd and no-knock warrants, as was used before Breonna Taylor's fatal shooting.
How recurrent networks implement contextual processing in sentiment analysis
Neural networks have a remarkable capacity for contextual processing--using
recent or nearby inputs to modify processing of current input. For example, in
natural language, contextual processing is necessary to correctly interpret
negation (e.g....
