lukasga··on Nobel Prize in Physics Awarded for Machine Learning and Neural Networks
The story is that it is because Alfred Nobel was cheated on by a mathematician (hilarious, but unconfirmed)

What does "Data flywheel" refer to here? Is it the continuous and immediate processing of user input while you're still speaking?
lukasga··on Leave No Context Behind: Efficient Infinite Context Transformers
Maybe a bit outdated now, but reminds me of LSTMs from the recurrent update of a memory / hidden state with gating. I remember one of the biggest problems with such RNNs being vanishing gradients as a result of the long context, which vanilla transformers presumably avoided by parallellizing over the context instead of processing them individually. I wonder how this is avoided here?
lukasga··on Tweets to Citations: The Impact of Social Media Influencers on AI Research
Love the site, but the one thing I am missing is instantly seeing what papers are trending right now, instead of having to manually select a timeframe. Think hacker news frontpage. Would be interesting to add a "hot" filter, or similar. Average weighting by exponential decay over time? Not sure how you usually do that with pagerank.
lukasga··on Ask HN: What is the state of art approximate k-NN search algorithm today?
Spotify recently open sourced Voyager (continuation of Annoy), which uses HNSW. https://github.com/spotify/voyager
lukasga··on StyleTTS2 – open-source Eleven-Labs-quality Text To Speech
Can relate to this problem a lot. I have considered starting using a Docker dev container and making a base image for shared dependencies which I then can customize in a dockerfile for each new project, not sure if there's a better alternative though.

lukasga··on ElevenLabs Launches Voice Translation Tool to Break Down Language Barriers
I saw that Spotify recently released a similar feature for selected podcasts, could anyone recommend some recent research papers related to voice translation? Would be really interested in reading!
lukasga··on Good-looking female students no longer get straight A’s when classes are virtual
This study was done at my uni, and the legitimacy and rigor of it was questioned and investigated by the university. However, it was ultimately not deemed to be inappropriate. Some interesting info is that the single picture that was shown to the "jury" of a student was handpicked by the author from Facebook, and that the jury consisted of high school students.

lukasga··on An Applied Mathematician Strengthens AI with Pure Math
Fascinating article, I feel like quanta always puts out high quality stuff. I don't know if I misunderstood though, but the article mentions:

"In subsequent steps of the algorithm, should it pick parameters that we have already picked before in earlier steps, or should we exclude those?"

Isn't it the training examples the two different types of sampling are considered for, instead of the parameters of the model?

lukasga··on Denoising Diffusion models from first principle in Julia
I'm doing my thesis right now in diffusion models (for audio) and have experienced a lot of the same things you mention. One paper which I found illuminating was this one: https://proceedings.mlr.press/v139/nichol21a.html

Particularly relevant to the noisy training you mentioned earlier is their alternative timestep sampling procedure they propose which seem to reduce gradient noise significantly judging from their experiments. Would love to hear or discuss if you have found any other design changes which have improved training / sample qualities :)

lukasga··on Truecaller launches new AI-powered voice assistant
I wonder which specific ML models they're using, and if it's something along the lines of Whisper
