I am a mac user, I have multiple iphones, ipads, airpods, macbook pros, and an apple watch. I have a lot of different chargers for them, its a huge mess and a waste to carry all of them, especially when charging. To charge all my devices I need to have usb-c, lightning, and the apple… Continue reading The universal magnetic Apple charger

I’m waking up too often at night
I noticed I have been waking up many time during the night, sometimes up to 10 times. Fortunately, I still fall back asleep, but I notice the quality is not as good. I don’t know what is going on here, but it tells me I need to do 3 things: Go back to focus on… Continue reading I’m waking up too often at night
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
A curriculum for teaching children about AI
This is a collection of topics I am writing about for fun to teach children about AI. Wired has a cool series where they discuss the same concept but in 5 levels: children, teen, college student, grad student, expert: https://www.wired.com/video/series/5-levels . This content would be equivalent to their children level. What is life – moving… Continue reading A curriculum for teaching children about AI
Review of “The entorhinal cognitive map is attracted to goals”
Paper: https://www.science.org/doi/10.1126/science.aav4837 The scientists did experiments where they let a rats learn a maze. On a daily basis they change reward locations of food. They measured firing fields of grid cells before rewards, during learning of reward locations, and after learning to understand the firing rates. They found that the grid fields moved toward the… Continue reading Review of “The entorhinal cognitive map is attracted to goals”
Some questions I would ask AI researchers
What work have you done in machine learning? What areas have you focused your research? Have you done any theoretical work vs applied work? Have you spent any time in neuroscience or cognitive science? Have you reimplemented any papers on your own? What is the biggest difficulty you find in working in AI? What is… Continue reading Some questions I would ask AI researchers

Either write something worth reading or do something worth writing.
Its a quote from Benjamin Franklin. Writing is such an important skill to explain your ideas and clarify your thinking. And doing something such as building and making is also incredibly important. If you can build either of these skills, you will be in an extremely powerful position, if you build out both, you will… Continue reading Either write something worth reading or do something worth writing.
