Earlier quoted context omitted.

The Myers-Briggs system distinguishes call these two perspectives "Sensing" (detail orientated) and "Intuition" (theory/model based) [not the best names]. And it posits that it's less a matter of importance people place on things and more that people literally notice different things and perceive the world differently (so it's not even just about remembering, it's about what you notice and how your mind represents th…

Meyers-Briggs is a fundamentally non-empirical model. I wouldn't recommend it as the basis for any argument or position concerning real world phenomena.

Simply because a model is abductive and not deductive or inductive does not strip utility of said model

As we all know "all models are wrong but some are useful"

Compression is a component of general intelligence. A few years ago I was very sceptical of machine learning ever leading to general intelligence. I've since changed my mind. There are a lot of parallels to this work and the concept of "embeddings" in machine learning. Intelligence requires the ability to generalize. A prerequisite for generalization is the ability to take something high-dimensional and reduce it to…

“Compression is a component of general intelligence.” if you say so “A few years ago I was very sceptical of machine learning ever leading to general intelligence. I've since changed my mind.” thanks for sharing “…both [human brains and artificial neural networks] are able to compress data into a _useful_ representation.” thanks for pointing this out

Could you please stop posting unsubstantive and/or flamebait comments to HN? You've been doing it a ton, unfortunately, and we have ban that sort of account. It's not what this site is for, and it destroys what it is for.

What we want here is thoughtful, curious conversation, not people bashing each other's comments or inflicting snark on each other or ideological talking points.

If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.

It all works this way (though a certain female family member would disagree, claiming to remember conversations word-for-word years later). But my memory works this way. A summary "party at so-and-so's house, weather was nice, overall vibe was ___". The rest is context. You know what the house/backyard is like, you know the general feel of that time of year, you know the crowd that usually comes, you can easily synth…

>I can build up a relatively vivid mental image of my walking route to school (from the bus terminal) over 40 years ago. Is it accurate? Who cares. Not only that, but by recalling and rebuilding memories, how gaps are filled in depends on your current mental state. For example, if I'm feeling depressed and brooding over past social interactions, I'll likely imagine people having meaner expressions or saying harsher t…

Just thought I’d share an example of how this memory issue manifests for me.

I listen to a lot of music and use it (like many) to index various stages of life - i even have playlists by year to help facilitate this.

The problem occurs when I listen back to music i was listening to in, say, 2008. All of a sudden, i’m transported back. But, each time i do this, the effect wears off a little, because their is some - let’s call it - “meta data” being written from the current moment in time im listening from which is adding new color to the initial index.

This effect has been studied and noted somewhere before, but i’ll have to dig up when i’m not on mobile.

My perception is that I've only collected "raw" materials, left unprocessed. Not sure if it's compressed and lossy or lossless. There's a quote that say like "if you can't explain, you don't really understand", I really hate this quote because I don't have to explain! Those necessary memory will come up, load into my processing unit and execute it.
