No. Distillation trains on a teach model's logits or output tokens.

I know right?

They have always been behind. Why would this time be any different?

mrfox321··on Q-learning is not yet scalable
Read the paper.

They control for the data being in-distribution

Their dataset also has examples of the problem being solved.

They didn't show this, they just increased the length where accuracy breaks down.

What's your leg circumference at, now?

Mine is also smaller, due to patella tendinopathy.

Who do you think the shareholders are?

What demographic are they?

mrfox321··on ByteDance's Recommendation System
It's because they originally built their recommendation system to recommend friends and their content. Here, the social graph makes complete sense as the foundation for their simple search algorithm. But as they expanded their recommendation capabilities, the features stuck around. It's the same reason why tech debt accumulates. Data sticks around in the same way code does. But data is even higher friction, since it's a superset of the code.
mrfox321··on ByteDance's Recommendation System
I mean, it's their serving infra, but not their features. See my reply in another parent comment.
mrfox321··on ByteDance's Recommendation System
It's simpler intuition but more complex from a data / ml perspective.

Their algorithm is really built around their features. Specifically, temporal representations of user interest:

https://ieeexplore.ieee.org/document/9458799/

The features used by their algorithm tells you what a user is interested, historically.

Contrast this to Meta, which uses the social graph as their features. Imagine features like the number of times a user likes another author's / cluster's content.

Tiktok will serve you $TOPIC because you have $INTERACTED with $TOPIC historically.

Meta will serve you $TOPIC because you have $INTERACTED with $PEOPLE who post $TOPIC, historically.

Meta only coincidentally gives you what you like.

Tiktok knows what you like.

This is the difference. This is why IG is losing.

mrfox321··on ByteDance's Recommendation System
IG users and Tiktok users were / are quite similar. Especially when Tiktok wasn't yet eating IGs lunch.
mrfox321··on ByteDance's Recommendation System
IG has plenty of data (I did ML at IG). Don't be naive.
mrfox321··on ByteDance's Recommendation System
Not true. Why do IG reels and YouTube shorts suck, then?

They clearly built something superior. And it can't seem to be matched by the biggest tech companies.

mrfox321··on Engineers do not get to make startup mistakes when they build ledgers
At a big co I worked at, the lack of consistency between trading systems caused money to (dis)appear (into)out of thin air.

Prior to one of these hiccups, I hypothesized, given how shitty the codebase was, that they must be tracking this stuff poorly.

This led to an argument with my boss, who assumed things magically worked.

Days later, we received an email announcing an audit one one of these accounting discrepancies.

JPMC proposed using crypto, internally, to consistently manage cash flow.

Not sure if it went anywhere.

mrfox321··on Brain learning differs fundamentally from artificial intelligence systems
Second order methods, and their approximations, can be used in weight updating, too.

20 to 15 is insane.

Are these low 15s or high 15s? Regardless, that's fantastic progress.

Do you respond better to intervals or longer aerobic efforts?

I ask because Ive always wondered if training should be specialized for fast/slow twitch runners.

Specifically, do you focus on strengths or weaknesses.

Let me follow you on Strava :p

mrfox321··on Why do tree-based models still outperform deep learning on tabular data? (2022)
When you need the best possible model, full stop.

E.g. finance

In a sufficiently competitive space, good enough doesn't cut it.

mrfox321··on How we got fine-tuning Mistral-7B to not suck
I guess op may be envisioning an end-to-end solution that can train a model in the context of an external document store.

I.e. One day we want to be able to backprop through the database.

Search systems face equivalent problems. The hierarchy of ML retrieval systems are separately optimized (trained). Maybe this helps regularize things, but, given enough compute / complexity, it is theoretically possible to differentiate through more of the stack.

For the same reason why he brought up his iq tests in the first place.

Because he self-identifies with some definition of iq.

Nit to your nit, which is incorrect w.r.t. parent reply:

A Fourier transform is not a projection, it's a change of basis represented by a unitary transformation.

A square orbit would require infinite acceleration. Specifically, a dirac delta.

This is my belief as well.

In California, the haves will have houses. The have nots will have ADUs.

Our world is structuring itself to (more) obviously reveal the wealth disparity.
