Question Is this a dumb data science project idea?

1 Upvotes

I’m applying to a data science program and wanted to do a small, unconventional project for my application.

My original idea was to use the program itself as a case study, combining social media engagement, follower data, information session attendance and university curricula to estimate the potential applicant pool and its characteristics without access to actual application data.

I started working on it but realized that some of the data-linkage methods could conflict with my country’s data protection laws.

Was the original idea even worth pursuing? What other projects could demonstrate similar analytical and technical skills?

I’m particularly interested in combining unconventional datasets to quantify things that aren’t easily measurable, rather than doing a generic ML project.

Discussion What Indian dataset are missing for your AI, ML or any research work in general ?

1 Upvotes

Hi r/datasets,

Before collecting or curating anything, I want to know what India-specific data people actually need.

If you've looked for India-related data and couldn't find it (or it was too small, outdated or badly licensed), tell me:

  1. What data-were you looking for?

  2. What for? (model training, research, a product, analysis)

  3. Type, scale and labels (e.g., 500 hours of Kannada speech with transcripts)

Even a one-line reply helps. Thanks!

Title: Microsoft Fabric's Data Days: AI @ Work is happening! (Nov 2 – Dec 15)

I recently discovered an ongoing Microsoft Fabric community initiative called Data Days: AI @ Work.

It's a series of community-led online sessions focused on Microsoft Fabric, Power BI, SQL and AI.

Some interesting upcoming sessions include:

* November 15: Blogging Your Way Into the Fabric Community.

* November 18: GIS Day 2026 – Where Data Insights Are Mapped (Fabric x Esri).

* November 19: Microsoft Fabric Masterclass: Build Intelligent Analytics Solutions.

* November 19: DP-700 – Microsoft Fabric Data Engineer Associate session.

What makes this interesting is the focus on real-world projects, practical demonstrations and learning from the community.

I think this could be particularly useful for students and beginners interested in data engineering, analytics and AI.

Event schedule and registration:

Explore Data Days: AI @ Work

Is anyone here planning to attend any of these sessions? Which topics are you most interested in?

Question I’m a sophomore CS major wanting to do a data engineering internship— how can I do it

1 Upvotes

Hi everyone, I’m currently a sophomore in Cs at college and I want to do some sort of data engineering internship or data engineering job in fin tech. I’m trying to teach myself python and build a ML model w AI and train it/study it so that I can understand it better. I kinda suck at leetcode and I’m not the best coder, I’ve never been to a hackthon( I’m trying to get into one) even though I’ve been coding since sophomore year of high school. I’ve done projects as well using HTML/CSS/Javascriot

I just wanted to give a backdrop of just whether I’m at (it’s ok to say that I’m a loser and behind, I get it)

How can I get on the track of doing data engineering? Does my interest in machine learning be able to aid me in achieving my goal? What roadmap can I follow?

Or should I just drop out lol??

Any advice or insight is appreciated!!

Resources Free tool: see which of your data science projects actually show skill, and what to add to the weaker ones

If you're building a data science portfolio, this might help. I built my startup: AI-Atlas that reads your public GitHub and tells you which projects count as data science or ML work, and why, pointing to the actual files.

What tends to make a DS project stronger:
- A baseline and a comparison, not just one model.
- Results written in the README, not only inside the notebook.
- Notebooks committed with their outputs.
- Honest evaluation: cross-validation, a held-out set, a confusion matrix.

If it finds nothing yet, it suggests three first projects in the language you already use. Free and no account needed , at getaiatlas.com

I'm a 17 year old student building this solo. Feedback from people learning right now is the most useful kind :)

Resources How to make a Legora-style legal conflict detector tool using only NLI and encoder models

1 Upvotes

Hey r/learndatascience! I’m Tabs, a legal engineer at Isaacus. I've been a software engineer for a long time and started dipping into data science this year.

I built an open-source legal conflict detector that finds deviations and gaps between pairs of legal documents using only encoder models and natural language inference. 

Inspired by the explosion of interest in discriminative models like TypeSafe AI’s Jev, I wanted to see how far I could get using smaller, non-generative models for the bulk of the legal document playbook review workflow. 

The theoretical benefits of a non-generative approach to this problem are enormous. As true clause-level pairwise review is a quadratic problem, it’s unfeasible to do at scale using a model like Opus or Astra. Comparing two average-sized documents with 133 clauses each would take 17,689 API calls, which is far too slow and expensive. 

Simply uploading the files directly to Claude or GPT is no remedy either. Decoders and agentic architectures don’t have fixed attention that lets them thoroughly analyse a document in one shot. Even with a multi-shot approach, they’re weak on recall and routinely hallucinate. 

My lawyer friends raise this problem constantly, and I couldn’t find an open-source solution to it, so I decided to build one myself. 

My pipeline pushes the bulk of the NLI, entailment and reasoning onto faster and more accurate legal encoder models. For the longest document pairs I sampled, the full pipeline ran in under 20 seconds. Unlike generative architectures, these models run a comprehensive pairwise comparison, and although they can still make false positive or false negative errors, those misses and misclassifications aren’t hallucinations (out-of-domain results introduced into the feature set). 

The pipeline works as follows: 

  1. Enrich: we enrich each document into a hierarchical tree of sections, clauses and subclauses. Clauses are the key atoms that the pairwise comparisons run on downstream. 

  2. Embed: we embed each clause as a vector. 

  3. Filter: we use a legal zero-shot classifier to drop items that aren’t provisions, like footnotes or signature blocks. 

  4. Shortlist: we keep each clause’s three most relevant pairs from the reference document, as long as their cosine similarity is at least 0.5. 

  5. Score: we use a reranker and a classifier to score each shortlisted pair. Each answers a question in the format it’s built for: the reranker scores how relevant text is to a search query (relevance), and the classifier scores whether a statement is true (NLI/entailment). 

  6. Sort: if a clause and its best match are on the same topic but have a high conflict score, it’s a deviation. If there’s no same-topic match, it’s a gap, i.e. the topic is in one document but not the other. 

That’s the whole conflict detection pipeline. On top of it, you can optionally plug in an LLM to summarise each finding in plain English or redraft a clause to favour the party you’re representing. Because the generative step only runs after the NLI and encoder stack has already decided what the conflicts are, it can’t hallucinate a conflict into existence. 

To demonstrate the pipeline’s power, we inputted Bob Iger’s 2011 and 2022 Disney employment agreements. The pipeline found many disparities and conflicts, and across most of them, the 2011 agreement was more favourable to Iger than the 2022 one. 

One interesting finding was a gap: the 2011 agreement had no intellectual property assignment clause, while the 2022 agreement makes Iger assign all work-related IP to Disney, with an exception for inventions he makes on his own time without company resources. 

The code is MIT-licensed, so it’s free for personal and commercial use. The guide walks through every step, so you can swap in your own models or make your own architectural changes wherever you like. 

Have fun, and let me know what you think! 😁

Question Some ML sources

Thumbnail reddit.com
1 Upvotes

Hi everyone,

I’m a 2nd-year engineering student (focusing on data engineering / data science) taking a statistical learning course. It covers loss functions, risk, bias-variance decomposition, cross-validation, linear models, SVM, kNN, and so on, and it follows ISL / Elements of Statistical Learning.

I’m looking for YouTube channels, courses, or sites that combine both of these:

Mathematical depth: where the formulas are actually derived and the logic behind each model is explained (why this loss, why this decomposition, what the optimization is doing), not just stated.

Simple, concrete explanations: worked examples and real-world intuition, in the style of Simplilearn or StatQuest, so the math doesn’t stay abstract.

What I’ve already tried: Simplilearn (good for the big picture but too light on math), StatQuest, and Stanford’s ISL lectures. They’re useful, but I haven’t found one resource that does both well for each model.

Ideally I’d like something that:

walks through a derivation and then applies it to a small numeric example,

connects the theory to code (Python/scikit-learn),

is free or cheap.

If you were learning this again from scratch, what would you use? And is there a better way to combine resources (for example, intuition first, then derivation) than what I’m doing?

Thanks!
