*Abstract: *Discriminating distinct objects and concepts from sensory
stimuli is essential for survival. Our brains perform this processing in
deep sensory networks shaped through plasticity. However, our understanding
of the underlying plasticity mechanisms remains rudimentary. I will
introduce Latent Predictive Learning (LPL), a plasticity model prescribing
a local learning rule that combines Hebbian elements with predictive
plasticity. I will show that deep neural networks equipped with LPL develop
disentangled object representations without supervision. The same rule
accurately captures neuronal selectivity changes observed in the primate
inferotemporal cortex in response to altered visual experience. Finally,
our model generalizes to spiking neural networks and naturally accounts for
several experimentally observed properties of synaptic plasticity,
including metaplasticity and spike-timing-dependent plasticity (STDP). LPL
thus constitutes a plausible normative theory of representation learning in
the brain while making concrete testable predictions.

*About VVTNS : Launched as the World Wide  Theoretical Neuroscience Seminar
(WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in
Memoriam (April 20, 2022), Speakers have the occasion to talk about
theoretical aspects of their work which cannot be discussed in a setting
where the majority of the audience consists of experimentalists. The
seminars, **held on Wednesdays at 11 am ET,**  are 45-50 min long followed
by a discussion. The talks are recorded with authorization of the speaker
and are available to everybody on our YouTube channel.*
