What are the best websites to find state-of-the-art (SOTA) deep learning models at the moment?
Hey everyone, sometimes when I want to explore the best state-of-the-art (SOTA) object detection or classification models, I find myself confused about which models are currently considered the best and freely available. I'm wondering what the best websites are to find the most recent news, as deep learning research is making overwhelming progress and it's hard to keep track.

Multilabel text classification on unlabled data
I'm curious what you all think about this approach to do text classification.
I have a bunch of text varying between 20 to 2000+ words long, each talking about varying topics. I'll like to tag them with a fix set of labels ( about 8). E.g. "finance" , "tech"..
This set of data isn't labelled.
Thus my idea is to perform a zero-shot classification with LLM for each label as a binary classification problem.
My idea is to perform a binary classification, explain to the LLM what "finance" topic means, and ask it to reply with "yes" or "no" if the text is talking about this topic. And if all returns a "no" I'll label it as "others".
For validation we are thinking to manually label a very small sample (just 2 people working on this) to see how well it works.
Does this methology make sense?
edit:
for more information , the text is human transcribed text of shareholder meetings. Not sure if something like a newspaper dataset can be used as a proxy dataset to train a classifier.

A visual deep dive into Uber's ML system to solve the billion dollar problem of predicting ETAs.
TL;DR: Uber follows a 2 layer approach. They use traditional graph algorithms like Dijkstra followed by learned embeddings and a lightweight self-attention neural network to reliably predict estimated time of arrival or ETA.

Should I learn a low level languages like c or c++? If yes which one?
Since the time got interested in AI and ML, I have always used python. My grip over python is pretty good now.
Recently I have been thinking if I should learn a low level language. I already know one high level language.
Do you think it will be beneficial to learn another language like c or c++ in the context of AI? Will learning a low level language help me in AI in some way?
If I should learn one which one should I choose?
Thanks

Best Computer Vision Framework in 2024?
Hi everyone,
I'm about to start my internship in Computer Vision, and I'd like to brush up on the basics since I've been primarily focused on NLP recently. For Computer Vision, I've only worked with PyTorch, but after doing some reading, I've realized that TensorFlow is a good alternative, but I am not sure.
So, would it make sense for me to learn TensorFlow now, or should I stick with PyTorch? If there are any other frameworks that you'd recommend, please feel free to share.

Are there any benefits of using two Nvidia RTX 4090 in a single computer?
Hey everyone! I'm diving into my PhD focusing on deep learning, I've got a chance to get two RTX 4090s from my faculty. However, I've learned that the 4090s don't support SLI or NVLink, suggesting that communication between the cards might not be very efficient. I'm pondering whether it's worth using two 4090s together, or if it might be overkill. My toolkit includes Python, TensorFlow, Keras, and occasionally Matlab for deep learning tasks. I mainly work with convolutional neural networks for audio classification. A larger VRAM pool would be beneficial, but I'm guessing this won't improve with a second GPU. At least, I could train models faster, right? I could also opt for two 3090s, but since one 4090 seems to outpace two 3090s speed-wise, that option seems less appealing. What do you guys think?

Stuck in a loop while Learning ML/Deep Learning and I feel whatever I have done can be replaced by a basic chatgpt lol
A little bit about myself,
I love data. Since childhood I have loved collecting and storing and playing with data, especially once I learnt Excel in my childhood. Hence I really feel this field suits me more than the webdev etc
The thrill while training a model is unparalleled to any other thing that I've ever done.
Coming to my current condition, I have a basic exposure in Deep Learning where I have done a couple of internship where I did transfer learning to train a model to classify a specific type of object.
I used chatgpt and google to guide me and trained the model, with an accuracy of 90% approx. Another project of mine involved predicting a image improvement (densenet, squeezenet) and (random forest, SVM) algorithm parameters based on features like skewness, contrast etc where I used random forest and outputs were satisfactory.
Again I used chatgpt and just trained, it seemed very rudimentary as I didn't know how to improve the model by myself.
I wouldn't say I learnt nothing but at the same time idk I still feel like a noob in Machine learning
Btw I have placements in a few months, hence I'm even more worried that should I continue to work on ML or just make basic MERN projects and get placed first.
Now the thing is, I don't have much idea about neural networks, or any maths behind it.
I built a NLP project, Twitter sentiment (i know very basic YouTube project) I understood the entire process and loved the new learning but I don't know ANYTHING about LSTM
I'm learning basics of ML now, like regression, KNN etc but Idk the maths behind it.
How should A guy like me proceed to learn Machine Learning and gradually move towards LLM/other topics
This isn't a normal roadmap cuz I have already worked on stuff but I'm still clueless.
Can someone please please guide me as to how can I proceed from here, and the stuff that I've done is that good enough for a fresher in ML or should I improve in some other direction.
Edit: I'm 20 years old. And a newbie in this field.
Edit: I have taken subjects like Algebra, Calculus, Probability in my uni. So I know the maths basics. It's just that I'm learning the maths related to ML now.

R The Era of 1-bit LLMs: All Large Language Models are in 1.58 Bits
https://arxiv.org/abs/2402.17764
Abstract
>Recent research, such as BitNet, is paving the way for a new era of 1-bit Large Language Models (LLMs). In this work, we introduce a 1-bit LLM variant, namely BitNet b1.58, in which every single parameter (or weight) of the LLM is ternary {-1, 0, 1}. It matches the full-precision (i.e., FP16 or BF16) Transformer LLM with the same model size and training tokens in terms of both perplexity and end-task performance, while being significantly more cost-effective in terms of latency, memory, throughput, and energy consumption. More profoundly, the 1.58-bit LLM defines a new scaling law and recipe for training new generations of LLMs that are both high-performance and cost-effective. Furthermore, it enables a new computation paradigm and opens the door for designing specific hardware optimized for 1-bit LLMs.

Switch from Classic Computer vision to Deep Learning
I develop classic Computer Vision algorithms on C++ and want to switch to Deep Learning area.
For now, I see these options:
Plan #1:
1. Join a small HW/mobile startup
2. Integrate/optimize neural networks (this usually requires C++)
3. Gradually move to NN finetuning.
This may be possible if NN training and integration is made by the same team. That's why the company should be small.
Plan #2:
1. Learn leetcode
2. Apply to FAANG-like companies for SE in test role to support AI/scientific infrastructure
3. Try to switch from testing utils to NN finetuning.
Plan #3:
1. Learn DL theory on excellent level
2. Join intern/junior position in bigtech
3. Hope to get a better offer for middle position from them
My skills:
C++: 5 YoE as a main programming language
Python: 2 YoE for auxiliary utils
DL: 1 year of commercial experience, utilized a few networks as black boxes
DL theoty: few online courses
Math: good level
Extra: 5 YoE in Classic Computer Vision
​
So, I have a couple of questions:
1. What do you think about these plans?
2. Maybe, you can share some relevant experience?
3. Do you have other ideas how to switch to DL with my experience?
4. Should I do pet projects to tell about them on job interview when the interviewer asks me about my DL experience?
​
I would also be happy to hear your stories if you did similar transfers.
Thanks in advance!

R P 10 times faster LLM evaluation with bayesian optimization
Recently I've been working on making LLM evaluations fast by using bayesian optimization to select a sensible subset.
Bayesian optimization is used because it’s good for exploration / exploitation of expensive black box (paraphrase, LLM).

Is overfitting always a bad thing?
As I understand, overfitting occurs when a model learns noise in the training data, so that it performs on training data higher than validation data. Overfitting is bad because overfit models do not generalize well on unseen data. So we use early stopping to prevent overfitting.
Now, I am training a CNN for image classification. At first, till the training accuracy reaches 95%, I see the same trend in validation accuracy. So till this point, there is no overfitting. But as I train the model from 95% to 99%, validation accuracy moves from 95% to 96%. By definition, this is overfitting, but the validation performance of the model is still improving. Is this kind of overfitting also considered bad?

Which NLP-master programs in Europe are more cs-leaning?
I'm (hopefully) going to finish my bachelors degree in Computational Linguistics and English Studies in Germany (FAU Erlangen-Nürnberg, to be precise) next year and I'm starting to look into masters programs. As much as I love linguistics, thinking about job perspectives I want to do a program that is much heavier on the computer science aspects than the linguistic ones. I sadly haven't been able to take any math courses and I doubt I'd be able to finish the ones you would have with a normal cs degree before finishing my studies, I do however have programming experience in Python and Java and I've also worked with Neural Networks before.
I'd like to stay in Europe and I also can't afford places like Edinburgh with those absurd tuition fees (seriously, 31k? who can afford that?). I know Stuttgart is supposed to be good, Heidelberg too, although I don't know how cs-heavy that is considering it's a master of arts. I've also heard about this European Erasmus Mundus LCT Program, although I wonder how likely it would be to get a scholarship for that. Also I'd be a little worried about having to find housing twice in 2 years.
tl;dr
looking for a cs-heavy NLP-master in Europe (or smth else that I could get into with basically no mathematical experience that enables me to work with Machine Learning etc. later) that also won't require me to sell a kidney to afford it.

D What comes first, math, or algorithm in research?
I'm learning meths behind diffusion right now (DDPM, Score-based, and other approaches). I'm wondering how exactly did researchers come up with the idea?
Does inventing new approaches go something like this?
1. We want to make better image generator.
2. Oh, the data will never be enough...
3. Let's multiply data - by adding some noise corruption
4. This this works well, what if we make a denoising network?
5. What if we make network that makes an image from pure noise?
6. That doesn't work, what if we did smaller denoising steps?
7. This works! Now, let's create some theory on why it works.
8. Write the paper
Or something like this?
1. We want to make better image generator.
2. We know "nonequilibrium thermodynamics" really well and want to try applying it somehow
3. We somehow come up with an algorithm that relies on math from that theory
4. It works!
5. We write the paper.
Which comes first usually? Math or Algorithm?

I am 71 with an all but phd dissertation math background, several years of teaching experience (up through Calculus and Prob/Stat). My programming skills are modest but improving. I have taken a number of machine learning and deep learning courses on Coursera and done quite well.

Why is ViT more commonly used than SWIN?
I'm still reading around but most every Computer Vision paper I read uses ViT as their backbone instead of SWIN or other similar architectures but why?
​
The ViT paper had to pre-train their model on the 303M image JFT dataset to beat earlier convolutional models on ImageNet whereas SWIN achieves better performance without any pre-training. I imagine SWIN would achieve comparable, if not higher performance on ImageNet if it was pre-trained the same way though admittedly I haven't seen any work to validate this idea.
​
Is this just a case of ViT being first so now everyone uses it as a default or is there another reason?

How to get out the loneliness of research career
Hi guys, I'm a ms student and I'm doing research under the guidance with a new AP in my university. H's a good person, has strong capability, and he always encourages us to follow our own thoughts. However, since he is a new AP, our lab only have 2 ms students including me and 0 phd student.
I feel like overwhelmed by the loneliness. When I come across problems, such as the derivation of formulas and some research stuff, I can't find a friend to ask. My only way of acquiring information from other people is my weekly meeting with my professor.
I tried to talk with other phds in my univ but they usually don't work on my field, i.e., unsupervised learning and world models stuff. One impressive moment is one day I deployed some docker apps to our lab server just for fun. I wanted to cheer for that but couldn't find anyone to talk with.
I'm determined to pursue a phd career but I can't stand for the loneliness and pressure (from both research and coursework since I'm a ms). The instructions given by professor is rather free because he doesn't want to be so rigorous and hopes to inspire our enthusiasm towards research, whereas I need to publish one paper before my phd application so that I can be competitive in the applicantion pool. However, even if I become a phd in those big schools, I'm afraid that I'll keep repeating this lonely life for 5 years, and I'll spend my life before my 30 as an upset person :(
Sorry for these cliche, I just can't hold myself.

D 3 years doing ML, no success yet. Is it common?
I'm working in ML research for 1.5 years now, more specifically medical imaging and previously as a DL Engineer for building a facial recognition pipeline. Despite a good understanding and all my focus I'm yet to make a good enough system or model for all many use cases I worked on.
From last 4 months I'm exploring 'learning from noisy label' I worked on 3 techniques, spent considerate time integrating target loaders but results were poor, even worse than baseline.
Previously, made a failed attempt to make a system identification using hybrid adaptive algorithm scheme but approach failed. Did write a technical report on that.
Also, on the otherhand, I do participate in online competition. Vanilla methods get me top 10-20% but when I try to improve on it, I always fail. None of my method work well, super frustrating despite all efforts.
I'm not trying to build a state-of-art model, but atleast expect myself to get over the previous baselines or work of any significance.
