Machine learning mercenary and brain boffin and at the National Institute of Mental Health (NIMH). Posts on mundane matters are written without the letter "e". My opinions, not those of my employer.

I'm currently developing a new course "Neuroscience for machine learners" that I hope to be able to make publicly available, and I'd love to hear what you think should be in it.

It's aimed at people with a machine learning background to learn a bit about neuroscience. My thinking is that neuroscience and ML have had fruitful links in the past, and may again in the future (although right now they're drifting apart). This course is designed to give students the background they'd need to be able to discover, understand and make use of new opportunities arising from neuroscience (if they do). I'm not trying to tell them only about the bits of neuroscience that we already think are applicable to ML, but to give them enough background to read and understand enough neuroscience to allow them to make new discoveries about what might be applicable to ML. The constraint is that it can't just be an intro to neuro course I think, because I'm not sure how compelling that would be to students with an ML focus. The course is 10 weeks and will have quite a practical focus, with most of the attention on weekly coding based exploratory group work rather than lectures. (Similar to @neuromatch Academy.)

I have thoughts about what should be on this course, but I'd love to know what you all think would be most relevant.

Heading to #OHBM #OHBM2023 soon. I compiled all multi-echo fMRI content at https://github.com/ME-ICA/ohbm-2023-multiecho If you use multi-echo fMRI on your poster/talk and want it added, let me know. @dowdlelt @tsalo @Nathan_Spreng @emdupre @laurenatlas @neuro_steel @esfinn @poldracklab

Now out in @CurrentBiology -- our paper on cortical pattern amplification with learning, w/ @KanakaRajanPhD šŸ§ šŸ“„

Below in thread: Huge perceptual improvement. No vis resp changes. Simple recurrent model. Relationship to recent S. Peron lab paper. +more.

What does it mean? Biological recurrent networks in vivo can change to accommodate totally new patterns of input. We provide those artificially w/ optogenetics.

Many groups use tedana for multi-echo fMRI data denoising. The code was opaque and brittle in ways that frustrated both users and developers. We have finally released a major refactor that shouldn't affect results, but will make the results more understandable and will make it easier for current and future developers to innovate. A longer summary of the changes is here https://app.tinyletter.com/#!/messages/10188201/report There's still a lot more that can be done, but this has been a huge group effort with @tsalo @emdupre @dowdlelt @KirstieJane & many others not on mastodon.

Nature Human Behaviour is strengthening its reporting requirements, banning results showing only p-values. Great in general, but I have a few quibbles...

https://www.nature.com/articles/s41562-023-01586-w

They want to see:
1) statistic (degrees of freedom) = value;
2) P = value;
3) effect size statistic = value; and
4) per cent confidence intervals = values.
Sure, all good but:

A) No mention of the importants of units; "effect size" suggest units don't matter and r or Cohen's d will suffice. I want to see an 'effect magnitude' with meaningful units.

B) Why %CI's? If the effect units are seconds, mm, etc, I'd want CIs in those units, right?

Points of significance - Nature Human Behaviour

The majority of empirical articles that we publish use null-hypothesis significance testing. In most cases, researchers rely on P values to establish the scientific or practical significance of their findings. However, statistical significance alone provides very little information that is useful for making inferences about scientific or policy significance. For this reason, we require authors to provide much more information than just P values — in this Editorial, we explain our requirements.

MCW Faculty Computational Neuroscientist

The Medical College of Wisconsin Neuroscience Institute invites applications for a tenure-track faculty position in Neurology and Neurosurgery at the rank of Assistant or Associate Professor, with specialization in computational science. Our language research group (https://www.neuro.mcw.edu/)

I’m very proud to share: A smartphone intervention that enhances real-world memory and promotes differentiation of hippocampal activity in older adults.

Over the last 8 years, we developed @HippoCamera as an easy-to-use smartphone app that embodies principles from memory science to record and replay brief but powerful memory cues of everyday events.
