An absolutely fascinating talk by Iris Zhou at Hiroshima University following 3 individuals who fell in love with AI, ending with a discussion on whether algorithmic love constitutes "real love" (from 31:40) youtu.be/RWPX-S7B1pw?...

Interesting tidbit I learned: 90% of SCZ patients don't have a parent with the diagnosis.
// Oof, probably a contributing factor to late diagnosis: parents don't know the symptoms and can't identify when psychosis happens until it's severe

This week, I'm reading Strong Imagination by @danielnettle.bsky.social, recommended to me by a biology colleague working on schizophrenia. It's fascinating to read research spanning biological evidence to social science.

Week 1 of a molecular neuroscience course - I don't know what I don't know. Also, it seems I don't know a lot ☺️

Next up on my sabbatical journey is this book by Stephanie Cacioppo. It's simultaneously intellectually invigorating and heart wrenching.

This is a super piece! I love LeDoux's historical note on his start with emotions and consciousness. One question I have is how a non-Western researchers might respond to your question. For example, see this workshop hosted at ACII in Japan, discussing kansei sites.google.com/view/coa2022

TIL about asymbolia for pain due to insula lesions. Asymbolics can perceive stimuli as painful and estimate pain intensity, but not have emotional reactions. Makes me wonder if pain mapping is a continuous ability? Can it be trained/learned?

Starting the first day of my sabbatical digging into Elusive Cures by @nicolecrust.bsky.social Can barely put it down and might finish it today! Lovely writing and very compelling.

Anyone see Geoff Hinton and Yann LeCun's takes on building in AI empathy and parental instincts as a means to AGI safety last week? Thoughts?

Here are a bunch of tasks and datasets in our field. Quality can vary (number of annotators etc), but maybe this helps?

7/ That's it for now. Was really surprised I had gone this long without knowing these basics. Grateful to my SFU neuro colleagues for teaching me tidbits and pointing me to resources like this beautiful Kandel textbook. I'll keep reading each week and take a couple courses this Fall. Excited! 😊

6/ Underneath the grey matter, we have white matter that is made up mostly of axons that connect more distant brain areas. It's white from the myelination of the axons, a process involved in long-term learning

5/ Brodmann visually segmented the cortex based on patterns of neurons in these layers. It turns out that the areas he visually segmented differed functionally as well, resulting in the Brodmann areas.

4/ Grey matter in the cortex (primarily in the outer surface of the brain) is composed mostly of neurons and local connections. The cortex has 6 layers. Layer 4 is mainly connections to the thalamus which receives much of the body's sensory input.

1/ The timing of input into a human neuron matters. If you have two action potentials entering a soma, arriving at the same time could cause it to fire. BUT the same inputs with some delay between each other might not. This is different from an artificial NN, where timing doesn't matter.

What are some basic things a computer scientist should know about the brain? I teach an Intro to AI course, and like many others, my slides include one diagram of a biological neuron that inspired the perceptron. But that's it! I'm just learning some of the things we don't teach 🤯 A thread 🧵

Wow, this paper is so cool. Collaborative filtering to model responses like preferences - love it! Reminds me of drift diffusion to model emotion response in this recent nature review paper. Still learning about it, but drift diffusion is also used to model preferences if I understand correctly.

Excited to dig into this. In the first couple of pages it talks about features of real world interactions that are usually filtered out of text-based systems (e.g. pauses, huh?, um, uh). Thanks @mzmttks.bsky.social for the recommendation!

Environments where robots can be helpful (forest fires, construction sites) are really loud. We'll need more ways to interact with robots other than verbal language. - Prof. Julie Adams @hri-conference.bsky.social

If the kids are working around a table then you can go hands free. In Japan, some of my auditory scene analysis colleagues from Kyoto University created an "egg" you can place on a table that does all the speech analysis and tracking, and has deployed it in elementary schools
