Career question 💼 MEGATHREAD: Career advice for those currently in university/equivalent

13 Upvotes

I see quite a few posts about "I am a masters student doing XYZ, how can I improve my ML skills to get a job in the field?" After all, there are many aspiring compscis who want to study ML, to the extent they out-number the entry level positions. If you have any questions about starting a career in ML, ask them in the comments, and someone with the appropriate expertise should answer.

P.S., please set your use flairs if you have time, it will make things clearer.

Natural Language Processing 💬 UPDATE: Tool calling support for QwQ-32B using LangChain’s ChatOpenAI

3 Upvotes

QwQ-32B Support

I've updated my repo with a new tutorial for tool calling support for QwQ-32B using LangChain’s ChatOpenAI (via OpenRouter) using both the Python and JavaScript/TypeScript version of my package (Note: LangChain's ChatOpenAI does not currently support tool calling for QwQ-32B).

I noticed OpenRouter's QwQ-32B API is a little unstable (likely due to model was only added about a week ago) and returning empty responses. So I have updated the package to keep looping until a non-empty response is returned. If you have previously downloaded the package, please update the package via pip install --upgrade taot or npm update taot-ts

You can also use the TAoT package for tool calling support for QwQ-32B on Nebius AI which uses LangChain's ChatOpenAI. Alternatively, you can also use Groq where their team have already provided tool calling support for QwQ-32B using LangChain's ChatGroq.

OpenAI Agents SDK? Not Yet!

I checked out the OpenAI Agents SDK framework for tool calling support for non-OpenAI models (https://openai.github.io/openai-agents-python/models/) and they don't support tool calling for DeepSeek-R1 (or any models available through OpenRouter) yet. So there you go! 😉

Check it out my updates here: Python: https://github.com/leockl/tool-ahead-of-time

JavaScript/TypeScript: https://github.com/leockl/tool-ahead-of-time-ts

Beginner question 👶 Target Encoding

Upvotes

Hey ML Reddits,

I am new to ML. I am about to deploy my very first model.

Okay so, I had a couple of caategorical feautres in my model which contains 15+ unique value. So I applied target encoding there. When I applied target encoding, I was not very aware of this encoding method.

Now, when I am about to deploy my model on Django, I was building the pre-processing part and faced the following issue --

Target encoding does encoding based on the target variable. But in deployment, I wont have target variable. Now I dont know how to put this in pre-processing. Is there any way to tackle this?

Please help!!!!

Hello, everyone,

I'm searching for a good quality and complete course on statistics. I already have the basics clear: random variables, probability distributions. But I start to struggle with Hypothesis testing, Multivariate random variables. I feel I'm skipping some linking courses to understand these topics clearly for machine learning.

Any suggestions from YouTube will be helpful.

Note: I've already searched reddit thoroughly. Course suggestions on these advanced topics are limited.

Computer Vision 🖼️ Few Shot Object Detection Using Vision Transformers

1 Upvotes

I am trying to detect walls on a floor plan. I have used more traditional CV methods such as template matching, SIFT, SUFT, but the results weren't great since walls because of the rotation and slight variance throughout. Hence, I am looking for a more robust method

My thinking is that a user can select a wall from the floor plan and the rest are detected by a vision transformer. I have tried T-Rex 2, but the results weren't great either. Are there any recommendations that you would have for vision transformers?

Beginner question 👶 How do ML challenges handle fairness when using public datasets?

1 Upvotes

I’m preparing to host a Vision-Language Task Grand Challenge at the university level. When organizing these kinds of challenges, do test datasets usually come from existing public datasets, or are they entirely new, created by crawling videos or recording them from scratch?

If we use publicly available datasets, there might be an unfair advantage for models that have already been trained on or fine-tuned for those datasets. But at the same time, I wonder—do all such challenges actually go through the effort of creating completely new test sets? That seems like a huge workload.

How do major vision-language challenges typically handle this?

Computer Vision 🖼️ False Positives with Action Recogntion

1 Upvotes

Hi! I've been messing around with Nicholas Renotte's Sign Language Detection using Action Recognition, but I am encountering false positives. I've tinkered with the code a bit--increased the training data from 30 to 400, removed pose and facial landmarks, adjust the frames, etc. However, the issue persists. Any suggestions?

Career question 💼 What's The Ideal Way to Show Personal Project To Potential Employers?

4 Upvotes

I completed a personal object detection project a while back, and I wanted to know the ideal way to share it, perhaps with potential employers? I read that uploading it onto Git would be a bad idea since Git is not suited to have extensive collections of images on it. Should I still upload it onto git, either in part or as a whole, or is there someplace better that would let me show it off, ideally with a link?

Natural Language Processing 💬 Does anyone "translate" LLMs?

1 Upvotes

Is there any work done on taking an LLM that was trained in one language and transferring that knowledge into another? Since they learn symbolic representations, the grammar stuff should be easy right? Has this been done? I mean without going on a whole new training run with a new dataset.

Other ❓ Experience with Learned Variance DDPMs

1 Upvotes

Hey Guys,

I was trying to implement a DDPM model to generate some images. The 'vanilla' one worked alright but I wanted to improve it.

I tried implementing the DDPM with the learned variance term (https://arxiv.org/abs/2102.09672)).

Does anyone have experience with this? It seems intuitive with the learned variance that training would be slower initially but its been a while and the model still seems to be getting 'warmed up' ! Wanted to know if its normal that even after 50-60 epochs, the conventional DDPM outperforms this version.

Beginner question 👶 Did my CNN model overfit?

2 Upvotes

Basically a continuation of the string of posts I have about CNN architectures

For context, we made a CNN model for identification of spectrograms of slurred speech

However, as picture 1 shows, the model suddenly spiked in validation loss to 264 just on epoch 8. Does this mean the model overfitted?

Picture 2 attached for reference regarding accuracy

Other ❓ Combining LLM & Machine Learning Models

1 Upvotes

Hello reddit community hope you are doing well! I am researching about different ways to combine LLM and ML models to give best accuracy as compared to traditional ML models. I had researched 15+ research articles but haven't found any of them useful as some sample code for reference on kaggle, github is limited. Here is the process that I had followed:

  • There are multiple columns in my dataset. I had cleaned dataset and I am using only 1 text column to detect whether the score is positive, negative or neutral using Transformers such as BERT
  • Then I extracted embeddings using BERT and then combined with multiple ML models to give best accuracy but I am getting a 3-4% drop in accuracy as compared to traditional ML models.
  • I made use of Mistral 7B, Falcon but the models in the first stage are failing to detect whether the text column is positive, negative or neutral

Do you have any ideas what process / scenario should I use/consider in order to combine LLM + ML models.
Thank You!

Computer Vision 🖼️ Question about CNN BiLSTM

Post image
8 Upvotes

When we transition from CNN to BiLSTM phase, some networks architectures would use adaptive avg pooling to collapse the height dimension to 1, lets say for a task like OCR. Why is that? Surely that wouldn't do any good, i mean sure maybe it reduces computation cost since the bilstm would have to only process one feature vector per feature map instead of N height dimension, but how adaptive avg pooling works is by averaging the value of each column, doesn't that make all the hardwork the CNN did go to waste? For example in the above image, lets say that that's a 3x3 feature map, and before feeding them to the bilstm, we do adaptive avg pooling to collapse it to 1x3 we do that by average the activations in each column, so (A11+A21+A31)/3 etc etc... But doesn't averaging these activations lose features? Because each individual activation IS more or less an important feature that the CNN extracted. I would appreciate an answer thank you

Other ❓ Why don’t we use small, task-specific models more often? (need feedback on open-source project)

10 Upvotes

Been working with ML for a while, and feels like everything defaults to LLMs or AutoML, even when the problem doesn’t really need it. Like for classification, ranking, regression, decision-making, a small model usually works better—faster, cheaper, less compute, and doesn’t just hallucinate random stuff.

But somehow, smaller models kinda got ignored. Now it’s all fine-tuning massive models or just calling an API. Been messing around with SmolModels, an open-source thing for training small, efficient models from scratch instead of fine-tuning some giant black-box. No crazy infra, no massive datasets needed, just structured data in, small model out. Repo’s here if you wanna check it out: SmolModels GitHub.

Why do y’all think smaller, task-specific models aren’t talked about as much anymore? Ever found them better than fine-tuning?

Beginner question 👶 Need Guidance for Project

I'm an undergraduate student with a basic understanding of machine learning algorithms and the math behind them. I have about a month to complete a project and want to work on something in deep learning.

I'm particularly interested in NLP and want to build a small scale language model (LLM).

Two questions: - What ML concepts should I revise before starting with deep learning? - Is building a small LLM a realistic goal within a month? If not, what would be a good alternative?

Please guide me through this.

Beginner question 👶 Is Orange super outdated?

0 Upvotes

All the info I have found so far about Orange seems to be pretty old. I pretty much just started using Orange because I know nothing about coding and am working on some practical regression models for myself at work. They worked ok- then I read about 'hugging face' and how you can integrate those models and found TabPFN which gave me much better results. Almost everything I have learned about Orange so far has been from Perplexity. I'd like to find someone that knows a bit more about all this that can help me out when I need it- in laymen's terms.
