When I was in college my friends and I did something similar with all of Donald Trump’s tweets as a funny hackathon project for PennApps. The site isn’t up anymore (RIP free heroku hosting) but the code is still up on GitHub: https:/&

This is a super common occurrence in training loops for ML models because PyTorch uses multiprocessing for its dataloader workers. If you want to read more, see the discussion in this issue: https://github.com/pytorch/p

Egocentric means that the sensors frame of reference is the same as the ego (self). The person walking around is wearing the sensors/glasses themselves & their pose is given as “ego pose”. This dataset is clearly targeted for resea

Yup! It's a U-Net style convolutional neural network that runs on the spectrograms. There's a short 2 page abstract here: https://archives.ismir.net/ismir2019/latebreaking/000036.pdf and they cite this p

Yeah I've heard of it but never used it. Looks like they have a backend/runtime for ONNX models as well ( https://pypi.org/project/onnxruntime-openvino/ ) neat! ONNX really is the universal format. If you

I think I said this already in one of my comments but I'm not a neuroscientist and I don't claim to be. That's why I think it's kind of pointless and silly for me (or any other engineer) to sit here and make arguments ab

I was going to post basic pitch from Spotify but it looks like billconan beat me to it. That said I can give you a bit more advice. The Spotify basic pitch model isn't too good at multi-track input. It's capable of it, but you may

I think you may be over-indexing on the word "selling". I didn't mean it literally as in for sale to you (the customer) directly. That is what Tesla FSD is claiming and I agree with you that we're some indeterminate amou

Yup! This kind of reconstruction is known as multi-view reconstruction. Though the cameras don't need to have a movable mount, they're already on a car which moves! The car moves and gives them a new "perspective" at eve

Yeah. I mean you're right and wrong at the same time imo. I won't hypothesize about how humans drive. I think for the most part it's a futile exercise and I'll leave that to the people who have better understanding of ne

As someone who works in the industry (disclaimer these are my own views and don't reflect those of my employer), something about the framing of this article rubs me the wrong way despite the fact that it's mostly on point. Yes it

You can use the onnx cpu runtime in python or c++ too. It doesn’t have to be rust. And if you want GPU support you can even run models saved in the onnx format on Nvidia GPUs with the TensorRT runtime. Honestly while ggml is super cool. It

I’m super confused… you’re agreeing that having a radar is superior but you’re disagreeing that it’s going to be a sore spot? How is that possible. Regardless of how you name the configurations (HW4, HW4.5 whatever, the naming is irrelevant

Yeah that's kind of what I was trying to say. You're right in that we predict the actions of others, but we don't do it in the same way. Even when we execute millimeter level maneuvers, we aren't explicitly measuring any

That's not what the article you linked says at all. Some HW4 vehicles that are shipping now are shipping without Radar (likely due to supply chain or cost issues). But HW4 was designed with a Radar in mind, it's present in the cod

This is a compelling argument at the surface level (that roads are designed for humans with vision) that quickly breaks down when you examine how Tesla constructs their self-driving system. Quick disclaimer that this doesn't reflect th

Yeah it's shocking to me how many people overlook this. Even if we pretended that the Tesla sensor suite was capable of FSD, it's not FSD if you have to disengage when the lens gets mud on it. Sensor cleaning is an integral part o

So with the disclaimer that these views don't reflect those of my employer, as someone who works in the industry I think this article is basically spot on. The only point I would add is that the top line cost for all these vehicles is

To some extent Tesla is already going to need to resolve this hardware discrepancy issue. The new HW4 revision vehicles will have 4D imaging Radar and forward mounted side facing cameras ( https://twitter.com/greentheonly&#x2
