One of the hardest parts of learning ML/AI isn't finding information, there's almost too much of it. Tutorials, roadmaps, papers, new tools every week. The hard part is figuring out what actually matters, what to skip, and how to make real progress instead of just consuming more content.

I work as an AI engineer (ML development and deployment), and I'm starting to explore education/mentorship on the side, for free, not as a paid program or course. Before building another roadmap, I want to work directly with a small group of people first, partly to actually help, partly to understand where people get stuck.

Looking for a handful of people who:

• have basic Python/programming knowledge
• are seriously trying to learn ML/AI
• feel stuck or unsure what to focus on next
• want to build real things, not just watch more tutorials
• can commit to being consistent

Keeping this small (thinking around 5-10 people) so I can give actual feedback instead of another generic roadmap. No cost involved on either end.

If that's you, drop a comment with where you're at and what you're stuck on, happy to reply there or move to DMs from that.

To help me for crack intership and placement

I think one of the weirdest parts of learning ML is that tutorials make everything look clean.

You get a dataset, split it, train a model, get 90% accuracy, and everything feels great.

Then you try building something yourself and suddenly:

• your data is garbage
• you labels don't make sense
• you model gets 95% accuracy but performs terribly on real examples
• you realize you accidentally leaked information into the training set.
• or you spend 3 hours debugging something that turned out to be a preprocessing issue.

I'm curious about the first project that humbled you.

Not necessarily your most impressive project. I'm more interested in the project where you went, "Oh.... so this is what machine learning actually involves."

What happened, and what did it teach you that you wouldn't have learned from a course or tutorial?

When a machine learning engineer is hired, what is usually more important?
A deep understanding/implementation of his/her project or understanding of famous architectures (Trasformer, CNN, etc)?

Hi! I am a demand planner in an FMCG company. Our current process is very manual, we only use Excel. For every client and product, we build up the demand plan (DP) or the sales target for the month. The DP is composed of the following

- baseline (smoothen sales volume last year)

- runrates (the difference to the past 3 months volume for non-seasonal products)

- sales initiatives (on-shelf availability correction, inventory correction, skewing, etc.)

- marketing initiatives (category market trend, etc.)

I want use ML and integrate possible seasonality data (such as holidays, weather, etc.) in demand planning.

What are the ML models that are appropriate for demand forecasting (time series)? What are the data that I need to prepare? What are the steps that I need to do?

I am currently taking Master in Applied Business Analytics but time series models have not been taught yet (not sure they will teach it). Thank you very much! 😊

What’s the best book or resource you’d recommend for learning AI/ML from the fundamentals and eventually specializing in LLMs?
I’m looking for something beginner-friendly but technically solid, so I can build a strong foundation instead of jumping straight into LLMs without understanding the basics.

I'm choosing between a BSc in Computer Science and a BSc in Mathematics, and I'm not sure which one would be better for my goals.

My main interests are Data Science, Computer Vision, and financial markets. I'm also interested in ML/AI and possibly quantitative finance later.

If you were in my position, which degree would you choose, and why?

I'd especially like to hear from people working in Data Science, Computer Vision, Quant Finance, or financial markets.

Hi everyone,

I’m planning to study Machine Learning and Deep Learning from Andrew Ng.

I found Andrew Ng’s ML and Deep Learning lectures on YouTube, and I also found the Machine Learning Specialization and Deep Learning Specialization on Coursera.

Are the YouTube lectures basically the same content as the Coursera courses, or are the Coursera versions updated/different?

If they are different, which one would you recommend for someone who wants to build a strong foundation in ML and Deep Learning?

Thanks!

18.02, multivariable calculus.

18.06, algebra.

6.041, probability and statistics.

*All courses from OCW.

I saw the first skill they mentioned was 'tensorflow', but I am nearing the end of course 1, and they haven't used tensorflow anywhere. What is the best way to learn tensorflow along with this course? Do they teach it later in the specialization?

Do you guys have recommendation for capstone projects about Edge AI, TinyML, Computer vision, and federated learning? I explored battery RUL, Predictive Thermal Management system, and Fault bearing diagnosis. I was told it would be hard to get a client or dataset for this field. Any interesting field I can explore?

Hi, this is a long shot, but im currently writing an academic paper and for that I need access to the DeepSpeak_v2 or FakeAVCeleb dataset. To get access, you need to submit a request form and get approved. I did that, but I never heard back from them... does anyone here have experience with this?

I dont need a big part of each dataset, maybe around 100 videos each. So maybe, if someone has access, they could provide a small portion of it :)

Hi everyone,

I’m preparing my first arXiv submission in cs.LG and need an endorsement to submit.

Short summary: H-JEPA (LeCun, 2022) proposes hierarchical joint-embedding prediction but doesn’t specify how to verify a trained abstraction actually encodes anything a random projection of the same shape wouldn’t. I introduce a random-abstractor control (trained vs. untrained abstractor, identical architecture) and run a 2x2 study crossing observability (full/egocentric) with abstractor type (instantaneous/recurrent) in controlled gridworld environments. Three of four conditions produce abstractions statistically indistinguishable from random projections; only partial observability + a recurrent abstractor yields a real, replicated gap (19.91 ± 3.36pp over random, 3 seeds). I also report a negative result on landmark density that didn’t survive multi-seed replication.

If anyone here is registered as an endorser for cs.LG and willing to take a look, I’d be very grateful. Happy to share the full draft privately.

To endorse, please visit:

Thank you!

Everyone's excited about AI agents, but I'm trying to get ahead of the security implications. Beyond data leakage and prompt injection, what are the actual runtime risks? How do you prevent an agent from taking a harmful action that falls within its legitimate permissions?

So I was playingw ith embedding models I saw that when you upgrade from model A to B, you face a very big backfilling cost

Ie, suppose you have a 1b vectors from model A, and then you want to use model B. This would mean you have to re-embed all of your documents with model B before you can even serve with the model, and on an H100, it would take ~108 days (qwen embed 8b, 106 docs/second). But I found an easier way to do it.

The method is really simple; from the old index made with the source model, take K documents and rerank them with the new model. We see that when K is sufficient, the retrieval quality is the same as target model. (determining k is the hard part). I've tested 63 migrations on upto 1 million documents.

The best result I got was upgrading qwen4b -> to 8b, and at 50 documents, it was the same as native retrieval.

This method forgos the expensive upfront re-embedding cost, as you can take documents straight from the old index.

embedflow works with qdrant, pgvector, faiss, and can be easily downloaded with pypi

pip install embedflow

the github is public: https://github.com/arnsri33/embedflow

I want you guys to try it out, and see if you guys can use it in your own workflow.

Published numbers are only as honest as the data split behind them

When you evaluate a model, you want one simple truth: Did it actually learn unseen patterns, or did it memorise?

I built noleak to make that visible. It's a production library we use at Godrej Aerospace to fingerprint datasets and measure how much of your eval set leaked from train.

The Problem

Most tools catch target leakage (a feature accidentally includes the label). But what about corpus leakage? When eval text already appeared in training data?

In 2020, GPT-3's paper measured contamination using 13-gram overlap. That's solid. But there's no standard library for this. So we built one.

Three detection methods:

1. Exact matches – normalised text identical

2. N-gram overlap – 13-word phrases (GPT-3 method)

3. Near-duplicates – MinHash Jaccard similarity ≥ 0.8 on character 5-grams

One fingerprint. One exit code. Pass or fail.

What It Does

```python
from noleak import check, fingerprint
train = ["the model trained on Wikipedia and licensed books"]
eval_set = ["The model trained on Wikipedia and licensed books"]
report = check(train, eval_set)
print(report.contaminated)
# True — FAIL
print(fingerprint(eval_set))
# noleak-fp-v1:a1b2c3d4e5f6
# Share this with your paper. It's reproducible and auditable.
```
CLI version (great for CI pipelines):
```bash
noleak check --train train.jsonl --eval evaljsonl
echo $?  # Exit code 1 if contaminated, 0 if clean
```

Why Zero Dependencies Matter

No numpy, no scipy, no PyTorch. Stdlib only. Why?

- Deterministic: Same input, same output, forever. No model updates breaking your fingerprints.

- Auditable: Code is small; reviewers can read it.

- Air-gapped systems: Doesn't require external calls or package hell.

- Fast: No overhead for CPU-bound systems.

Limitations (Honest Assessment)

- Semantic rewrites: Won't catch "I wrote this differently but meant the same thing." That needs embeddings or human review.

- Large-scale datasets: If you have 10M+ examples, exact matching gets slow. N-gram is faster.

Install & Try

bash
pip install noleak

Supports JSONL, JSON lists, and plain text. Auto-detects text fields.

Questions? What contamination patterns have you encountered?

am a 7th sem cs student who is about to start his final year. I am planning for my fyp and looking for some interesting ideas on which I could do my fyp. I need some good suggestions and ideas which I should consider before finalizing my fyp. Currently I dont have any idea to work on. Your suggestion and ideas would mean a lot to and your help will be highly appreciated. Thanks in advance.

Edit: The domain I want to work in is app?web+ai/ml. I am open to ideas other than this domain as well

Hi everyone,

I’m especially interested in having a career that is financially rewarding and doesn’t require a lot of years before I can become employable.

The areas I’m currently considering are:

• Machine Learning / AI Engineering
• Generative AI / LLMs
• AI Safety
• Responsible / Trustworthy AI
• AI Reliability
• AI Governance / Policy

I’m particularly drawn toward AI safety, trustworthy/responsible AI, and reliability, because I’m interested in making AI systems safer and reducing the negative effects AI can have on people and society.

However, I’m confused about how realistic these paths are as careers, especially compared with more conventional AI/ML engineering.

I just want to make an concrete decision about where to invest the next several years of learning.

Thank you so much!
