Notes on “A unified theory for the origin of grid cells through the lens of pattern formation”

I just read the paper, I’m still processing it, but here are some of my notes, thoughts and questions. https://papers.nips.cc/paper/2019/hash/6e7d5d259be7bf56ed79029c4e621f44-Abstract.html 3 Main models types in neuroscience: Descriptive explanations delineate an abstract characterization of aphenomenon, while mechanistic and normative explanations bridge abstractions of different levels.Mechanistic explanations show how a phenomenon emerges from lower-level components (e.g., howcircuit… Continue reading Notes on “A unified theory for the origin of grid cells through the lens of pattern formation”

Improve your learnings while reading by asking yourself pointed questions

I was just listening to a talk from Jim Kwik and he spoke about how retained more information while reading. He states its a complete waste of time if you are reading and not retaining information. He consciously asks 3 questions and takes notes as he is reading. How can I use this information? Why… Continue reading Improve your learnings while reading by asking yourself pointed questions

Notes on “Design Principles of the Hippocampal Cognitive Map”

Paper link: https://papers.nips.cc/paper/2014/hash/dfd7468ac613286cdbb40872c8ef3b06-Abstract.html “We also propose that grid cells compute the eigendecomposition of place fields in part because is useful for segmenting an enclosure along natural boundaries. When applied recursively, this segmentation can be used to discover a hierarchical decomposition of space. Thus, grid cells might be involved in computing subgoals for hierarchical reinforcement learning.”… Continue reading Notes on “Design Principles of the Hippocampal Cognitive Map”

A review of “Grid-like Neural Representations Support Olfactory Navigation of a Two-Dimensional Odor Space”

I just finished reading “Grid-like Neural Representations Support Olfactory Navigation of a Two-Dimensional Odor Space” It’s an interesting paper that shows that olfactory(smell) seems to be represented with grid-like codes in the brain. The authors read and reference a bunch of papers where other researchers test if grid cells can represent other kinds of sensory… Continue reading A review of “Grid-like Neural Representations Support Olfactory Navigation of a Two-Dimensional Odor Space”

Evidence of Compositionality in the human brain

Artificial Intelligence and Cognitive Science researchers have taken for granted that compositionality exists in the human brain. Fodor , Chomsky, and many others have spoken about the human brain ability to create infinite meaning from a finite set of tokens (words). There are people who argue that the brain is not compositional. You can read… Continue reading Evidence of Compositionality in the human brain

NSM notes

I have been studying natural semantic metalanguage (NSM). It has been studied and cross-referenced fom 30+ languages. the core 65 changes several times, in the beginning it was 13 core concepts. It is as objective as it can to study human language, but of course there is still some subjectivity in it. Some words they… Continue reading NSM notes

Sci-Hub is one of the greatest contributions to humanity in our lifetime

What is the point of academic research? In my mind it is to accelerate human understanding and civilization. If researchers publish research, it should be available for anyone to research. If people want to view that research, it should be available for anyone to view without paying some crazy fee. A large portion of academic… Continue reading Sci-Hub is one of the greatest contributions to humanity in our lifetime
