DOI: 10.1101/2022.01.10.475663
Abstract: Neural system identification aims at learning the response function of neurons to arbitrary stimuli using experimentally recorded data, but typically does not leverage normative principles such as efficient coding of natural environments. Visual systems, however,… read more here.

Active fixation as an efficient coding strategy for neuromorphic vision
Sign Up to like & getrecommendations! Published in 2022 at "Scientific Reports"
DOI: 10.1101/2022.09.29.510091
Abstract: Contrary to a photographer, who puts a great effort in keeping the lens still, eyes insistently move even during fixation. This benefits signal decorrelation, which underlies an efficient encoding of visual information. Yet, camera motion… read more here.

DOI: 10.1146/annurev-vision-112122-020941
Abstract: Some visual properties are consistent across a wide range of environments, while other properties are more labile. The efficient coding hypothesis states that many of these regularities in the environment can be discarded from neural… read more here.

DOI: 10.1371/journal.pbio.3001889
Abstract: Activity of sensory neurons is driven not only by external stimuli but also by feedback signals from higher brain areas. Attention is one particularly important internal signal whose presumed role is to modulate sensory representations… read more here.

DOI: 10.1371/journal.pcbi.1007476
Abstract: In many sensory systems the neural signal is coded by the coordinated response of heterogeneous populations of neurons. What computational benefit does this diversity confer on information processing? We derive an efficient coding framework assuming… read more here.

DOI: 10.32348/1852.4206.v9.n1.14650
Abstract: There is a growing debate within the philosophical community about the unity or disunity of neuroscience. The new Mechanist philosophers claim that neuroscience exhibits a mosaic unity –one in which different explanatory models may contribute… read more here.

DOI: 10.3389/fncom.2022.929348
Abstract: While it is universally accepted that the brain makes predictions, there is little agreement about how this is accomplished and under which conditions. Accurate prediction requires neural circuits to learn and store spatiotemporal patterns observed… read more here.

Adaptation of olfactory receptor abundances for efficient coding

DOI: 10.7554/elife.39279
Abstract: Olfactory receptor usage is highly heterogeneous, with some receptor types being orders of magnitude more abundant than others. We propose an explanation for this striking fact: the receptor distribution is tuned to maximally represent information… read more here.

DOI: 10.7554/elife.54347
Abstract: Previously, in Hermundstad et al., 2014, we showed that when sampling is limiting, the efficient coding principle leads to a ‘variance is salience’ hypothesis, and that this hypothesis accounts for visual sensitivity to binary image… read more here.
