*Abstract: *The brain is one of the most energy intense organs. Some of
this energy is used for neural information processing, however, fruitfly
experiments have shown that also learning is metabolically costly. We will
present estimates of this cost and introduce a general model of this cost,
and compare it to costs in computers. Next, we turn to a supervised
artificial network setting and explore a number of strategies that can save
energy needed for plasticity. Either by modifying the objective function,
by restricting plasticity, or by using less costly transient forms of
plasticity. Finally, we will discuss adaptive strategies and possible
relevance for biological learning.

*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.*
