    New blog post: Contrastive Self-Supervised Learning. Contrastive methods learn representations by encoding what makes two things similar or different. I find them very promising and go over some recent works such as DIM, CPC, AMDIM, CMC, MoCo etc.

    I am very excited, to finally share this: Using a functional approach we uncovered a mechanism for whitening, a fundamental computation that decorrelates neuronal population activity for pattern classification by memory networks.

    Distributional reinforcement learning (RL) algorithms predict the entire ‘distribution’ of future rewards not just the average and improve the AI performance. This work presents evidence that the brain’s dopamine system uses distributional RL.

    Are cortical excitatory synapses analog or discrete? Being able to analyze 1000’s of synapses from a proofread EM volume finds evidence for two states, one bigger than the other. 1st analysis paper from our EM data, led by , et al!

    Four years of work for ten successful experiments: electrophysiology and electron microscopy of the very same neocortical synapses reveal multivesicular release and finally show how synapse size predicts synaptic strength. Now out as a preprint:

    What's hidden in an overparameterized neural network with random weights? If the distribution is properly scaled (e.g. Kaiming Normal), then it contains a subnetwork which achieves high accuracy without ever modifying the values of the weights... (/n)

    How is the wiring of the brain encoded? In "A Genetic Model of the Connectome" we take a network science approach to how a reproducible wiring diagram can be produced from interactions between expressed genes! More below: 👇
