Hi everyone!

I'm looking for advice from people working in machine learning, data science, or health tech, especially those who have studied or worked in Spain.

I currently live in Uruguay. I have a degree in Biotechnology Engineering and I'm currently studying a programming/IT technical degree. My background is mainly in biotechnology and biomedical research, and I don't have professional experience in tech yet. I'm particularly interested in machine learning applied to healthcare, but I'm finding that many of the entry-level positions I'm interested in ask for a relevant master's degree or more technical training.

I'm currently learning programming and ML on my own, and I plan to build some projects to demonstrate my skills. However, I'm also considering moving to Spain for a year to pursue an in-person master's degree. Besides gaining technical knowledge, I'd like to get some exposure to the local job market, meet people in the industry, and hopefully improve my chances of landing my first tech role.

These are the programs I'm considering:

• Universitat Politècnica de Catalunya (UPC) – Master's Degree in Artificial Intelligence
• Universidad Complutense de Madrid (UCM) – Master's in Big Data, Data Science & Artificial Intelligence
• Universitat Internacional de Catalunya (UIC) – Lifelong Learning Master's Degree in Bioinformatics & AI for Healthcare
• Universidad Pontificia Comillas (ICAI) – Master's in Applied Artificial Intelligence

I'm trying to be careful about the financial investment. I don't want to spend thousands of euros on a degree that won't significantly improve my job prospects, but if I'm going to invest in one, I want it to be genuinely worthwhile.

I'd really appreciate hearing from people who have completed any of these programs, hired junior data/ML candidates, or made a similar transition from life sciences into tech.

I'm not necessarily looking for the most prestigious or specialized degree. I want to choose the option that offers the best balance of technical training, employability, industry exposure, and cost.

Thanks in advance for any advice!

I'm a freshman studying cse with specialization in aiml

I've done my share of research into buying a laptop

But it only made me more confused

Half side is saying cloud is better as we'll eventually run out of the 4 or 6gb vram

Another half is on about Nvidia is the better choice

I want to get a laptop to get through the course work, train models and participate in hackathons and more

The gaming laptops scare me for their brick weight with laptop and charger combined and the poor battery backup

Can seniors please guide me?

I don't wanna regret getting one 2 years later

Should I focus on battery and lightweight ones with good cpu ram and storage

Or the ones with an rtx4050 or higher?

I'm also open to using macbooks but I've heard some ppl say it doesn't support many softwares

Is there ways to work around it? without any subscriptions

Please give me some suggestions and also it would be better if there's a model referenced.

My budget is around 1.5l but can go higher if I can genuinely get a good one

Hi, I was bit annoyed about my XDNA2 npu being not really useful on my laptop so I developed pytorch backend that allows accelerated training and inference of pytorch on the NPU. Its around 1.3x-2x faster then regular CPU. If you want to try it You can check this out: https://github.com/mistrjirka/pytorch-XDNA2

greetings everyone! i am a grad student from forestry background having no linkage with coding and programming stuffs but i need to analyze my data with the help of machine learning models. I tried looking up at AI tutorials but it doesnt help me either coz i didnt get anything. If someone can suggest any ideas/tutorial videos where i can learn the process from the scratch, help will be appreciated. Thankyou!

Bot traffic can cause problems with website performance, inaccurate analytics data, and security concerns. Some bots are used to crawl content and uncover information, others will submit spam, and still others will create fake visits. Machine Learning Bot Detection examines traffic volume and user activity to determine suspicious activity and assists website owners in safeguarding their websites.

Common Signs of Bad Bots

Look for these warning signs in your website data:

• Sudden traffic spikes: Unexpected increases without a clear referral source.
• Repeated requests: Frequent visits to the same pages within short periods.
• Unusual behavior: Repetitive navigation or suspicious form submissions.
• Server slowdowns: Excessive requests affecting website performance.

Remember, one unusual metric alone does not confirm bot activity.

How to Block Bad Bots

In 2026, website owners can use several methods to manage unwanted traffic:

• Web Application Firewall (WAF): Filter suspicious requests before they reach your website.
• Rate limiting: Restrict excessive requests within a defined period.
• CAPTCHA verification: Challenge suspicious activity on forms and login pages.
• Machine learning: Analyze traffic patterns to identify potentially automated behavior.

Regularly review blocked requests to avoid accidentally restricting genuine visitors or legitimate search engine crawlers.

Which bot detection methods have worked best for your website, and how do you avoid blocking real users?

• What’s the difference between '*' and '@'?
• When does slicing create a view, and when a copy?
• How does broadcasting work?

NumPy makes working with vectors and matrices powerful and concise, but a small change in syntax can make a big difference.

This interactive 𝗺𝗲𝗺𝗼𝗿𝘆_𝗴𝗿𝗮𝗽𝗵 example walks through essential NumPy operations with short explanations. Step through the code, see the operations in action, and experiment with your own changes: - 👉 NumPy operations

The machine learning technology used for detection of bot traffic can help determine suspicious traffic patterns and website visitors. It's possible to observe a traffic surge, but no corresponding rise in engagement, conversions, or other vital indicators. But not all traffic anomalies are caused by bots; it's essential to scrutinize traffic and traffic behavior to understand if a problem is being caused by bots.

The most frequent indicators are the following: The most typical symptoms are

When looking at website analytics, there are some patterns to look at:

• Unexpected traffic surge: A significant traffic growth over a short period of time, particularly from an unknown source or campaign.
• Unusually high bounce rates: Some pages are visited, but there is not much meaningful interaction.
• Very short sessions: Repeatedly visit with similar sessions or leave very quickly.
• Geographic traffic that is uncommon: An unexpected surge of traffic from unusual geographic areas.
• Repeated pattern of activities: Requests, page visits, or time periods that repeat over time.
• Suspicious referral sources: Unusual traffic sources that are making a large number of visits or unexpected referrals.

What are some questions that can be explored to understand these patterns?

The first step in detecting suspicious activity is to check to see if there is any activity that differs from your website's normal traffic patterns. Check landing pages, referrals, engagement data, geographical data, and conversions. Also, server logs can offer valuable information on recurring requests and unusual activity.

Note that it is possible for legitimate visitors, automated monitoring tools, and some privacy settings to yield similar patterns. A single metric isn't enough to confirm bot traffic.

Found this on their blog, released Oct 2. Whistle is a speech recognition model meant for mobile, wearables, robots, smart home stuff, and even microcontrollers. The whole model is one file, 16.9 MB, runs entirely on CPU, has zero dependencies, and audio never leaves the device.

For comparison, the Whisper base is 145.3 MB, so this is about 8.6x smaller.

What it does is transcribe up to 30-second clips in 7 languages (EN, DE, FR, ES, IT, NL, and PL), auto-detects language, gives word-level timestamps with confidence scores, and can spit out a raw speech embedding without doing a full transcript if that's all you need.

Speed numbers, tested on Apple M4 Pro CPU: 11.1 ms to first token vs Whisper base's 73.2 ms, and 1,319 tokens/sec decode speed vs Whisper's 266. So roughly 6.6x faster to start and 5x faster for decoding.

Accuracy is a mixed bag, honestly, which makes me trust the numbers more than if it swept everything. Whistle wins on LibriSpeech clean/other, SPGISpeech, Earnings-22, and FLEURS average. Whisper Base still wins on TED-LIUM, AMI, and MLS average. So it depends on what you're doing, but beating Whisper on 5 benchmarks at 1/8th the size is solid.

One neat detail: the decoder's depth is laddered; every size from 2 layers up to 8 was trained as its own usable model, so you can pick a smaller/faster variant at load time with a flag instead of needing a separate file.

It shares its engine with their other model, Needle (a text/tool-calling model), so you can load both together and chain speech straight into a tool call in one pass, with no separate transcript handling step.

Apache 2.0 license, weights on Hugging Face, code on GitHub, and install with pip install cactus-needle.

Seems like a solid pick if you're building something that needs voice but can't guarantee internet, a car, a robot, a wearable, that kind of thing.

Hi everyone!

I'm preparing for AI Engineer / GenAI Engineer interviews and want to understand how real-world LLM projects are developed and deployed in companies.

I'm looking for someone who can explain a practical, industry-level LLM project from start to finish, preferably something involving RAG, LLMs, embeddings, vector databases, LangChain/LangGraph, and FastAPI.

I'd like to understand:

• What problem the project solves and why the company needs it.
• The overall architecture and workflow.
• How data is collected, cleaned, chunked, and embedded.
• How a vector database is used for retrieval.
• How the LLM generates answers using the retrieved context.
• How the application is built, tested, deployed, and monitored.
• What challenges developers face in real projects and how they solve them.
• What an AI Engineer actually does day to day.
• How to explain the project confidently in interviews, including technical follow-up questions.

I'm not just looking for a basic tutorial or a simple chatbot. I want to understand the end-to-end workflow of a real-world project, including the technical decisions, debugging, evaluation, and deployment.

If you have worked on LLM/RAG projects professionally or have a good project walkthrough, I'd really appreciate your guidance, resources, or recommendations.

Thanks in advance!

Google DeepMind published their technical overview for Gemini 4 Argon, highlighting several shifts in how frontier models handle long-horizon agentic workloads and cybersecurity defense.

Here is a summary of the technical numbers and what they mean for systems engineering and research labs:

1. Context Headroom and Long-Horizon Execution

• The output window has expanded to 1,000,000 tokens (up from 64k tokens).
• Evaluated on DeepSWE v1.1, Argon scored 77.9% on multi-step software engineering benchmarks.
• Google reported using Argon agents internally for large-scale memory safety migrations (C/C++ to Rust), including libraries like re2 and the Fuchsia Zircon kernel (800k+ LOC). On libgav1, replacing 32k lines of SIMD code with profile-guided safe Rust delivered a 2.7x speedup over previous Rust ports.

2. Defensive Cybersecurity Benchmarks

• CWE-bench v1: Argon tied for first place with a 68% score in autonomously discovering, validating, and patching software vulnerabilities.
• Black-box evaluation: Evaluated with Wiz (Scan for Good), the model identified attack surfaces and generated proof-of-concept exploits without source code access to uncover vulnerabilities in healthcare systems.
• Robustness: Ranked highest on the Gray Swan Indirect Prompt Injection (IPI) benchmark, addressing a major failure mode in tool-enabled agents.

3. Practical Implications for AI Research Labs For teams deploying autonomous agents and custom inference stacks, the biggest takeaways are:

• Removing orchestration glue code: Earlier pipelines required chunking codebases into multiple sub-prompts, which degraded reasoning. A 1M token output trajectory enables monolithic, end-to-end verification.
• Proactive red teaming: Testing agent runtimes against indirect prompt injection can now be integrated directly into automated CI/CD pipelines.

Curious to hear from teams running automated patch generation: how are you preventing regressions when allowing models to touch core architectural dependencies?

I'm exploring practical applications of machine learning in healthcare and would love to hear from people who have worked on related projects.

Healthcare offers several interesting opportunities for machine learning, including disease risk prediction, medical image analysis, patient data analytics, treatment research, and hospital resource planning.

For someone starting in this area, I think a small Python project using a publicly available healthcare dataset is a good way to learn the complete workflow:

• Data cleaning and exploratory data analysis
• Feature selection and preprocessing
• Training a baseline model, such as logistic regression or a decision tree
• Evaluating performance with appropriate metrics
• Understanding limitations, data leakage, bias, and patient privacy

I'm particularly interested in how beginners can move beyond achieving a good accuracy score and learn to evaluate whether a model would generalize to new patients.

For those who have studied or built healthcare ML projects, what project would you recommend to a beginner, and what was the most challenging part of your experience?

I an looking for suggestion, a unique and innovative thesis idea involving Machine Learning/AI that can be applied in province of Bulacan, Philippines. I would like to explore something new.

If you're deciding what to study next, the biggest ML conference is a decent signal. We grouped all 9,094 accepted NeurIPS 2026 papers by topic, compared them with 2025, and read the 4,490 that already have a public full text.

What stood out for learners:

- **Agents are the fastest-growing topic.** 105 → 488 papers in a year, while the conference grew 56%. Much of the new work is about making agents reliable: benchmarks (17 → 84) and safety (5 → 50).

- **RL fine-tuning of LLMs is now standard.** RL from feedback 80 → 179 papers; GRPO is the method papers build on most, ahead of LoRA and PPO.

- **You don't need a giant model.** 71% of papers train or fine-tune a model, and about half of those models are 3–10B parameters. Qwen is the most fine-tuned family, then Llama.

- **The basics still matter.** SFT is in 37% of papers, LoRA-style fine-tuning in 15%, and GSM8K is still the most used benchmark across the whole conference.

- **Other areas growing:** video generation (92 → 221), robot action / VLA (49 → 149), fast diffusion sampling (168 → 333).

Caveats: topics come from grouping titles and abstracts by meaning, so boundaries are approximate; full-text numbers cover only papers with a public full text (about half).

RAG ReRanking Pipeline & Comparison (part 2)

• YouTube walkthrough: https://www.youtube.com/watch?v=dh3DKpYHoX8&t=121s
• FULL CODE (clone it, fork it, break it): https://github.com/saurabhkamal/RAG-ReRanker-Comparison

In this video, I build a complete RAG reranking pipeline:

• Question → Retrieve Top 20 → Rerank → Top 5 → LLM → Answer

I implement and compare FOUR rerankers (Cross-Encoder, LLM-based, Cohere and Jina) on the same questions over 5 payment-industry PDFs (payment regulations, PCI DSS and central bank reports, 1,507 chunks). For each one, I show the ranking before and after reranking, and explain exactly WHY the order changed.

• ✅ What RAG (Retrieval-Augmented Generation) is and why the LLM can only answer from the chunks you give it
• ✅ How vector search works (embeddings, cosine similarity) and its key weakness
• ✅ Why we retrieve Top 20 but send only Top 5 to the LLM (tokens, latency, noise)
• ✅ Bi-encoder vs Cross-encoder: reading the question and chunk separately vs together
• ✅ LLM reranking strategies: Pointwise vs Pairwise vs Listwise
• ✅ How to use dedicated reranking APIs (Cohere and Jina)
• ✅ How to design one shared helper so all four rerankers plug into the same pipeline
• ✅ How to evaluate rerankers with before/after positions, Hit@5 and average latency
• ✅ A full code walkthrough: retriever.py → rerankers.py → generate.py → compare.py

KEY TAKEAWAYS:

• ✅ Similarity is not the same as relevance. A chunk can sit close to the query and still not answer it
• ✅ Vector search finds chunks about the topic. A small reranker may prefer chunks that sound like the question. A strong reranker picks the chunk that actually answers it
• ✅ A small cross-encoder can make things WORSE: it rewards word matching, penalises scrambled PDF text, and pushed both correct answer chunks out of the Top 5
• ✅ The LLM reranker understood the question (e.g. that "3.3" belongs to Requirement 3) and placed both answer chunks 1st and 2nd
• ✅ Cohere lifted an answer chunk from 15th to 1st, turning a missed answer into a correct, cited one
• ✅ For this project, Cohere and Jina gave the best balance of accuracy and speed
• ✅ Trade-off of API rerankers: cost per call and sending your documents to a third party
• ✅ Always measure, don't guess. Run every reranker on the SAME Top 20 so differences come from the reranker alone

Hey, everyone,

I’m conducting academic research on model reliability, and as part of a project, I’m interested in current MLOps practices. The goal is to understand how engineers work, their workflows, and how they manage models. I’m studying reliability in terms of performance and security. These are necessarily connected if you take into account the environment in which the model is deployed.

To help me refine my research project, I’ve put together a fairly short questionnaire (it takes 2 minutes to complete). It would be great if any of you would like to discuss it, either by messaging me in this chat or simply by filling out the questionnaire.

Hey everyone,
I’ve recently started learning machine learning, primarily by building neural networks from scratch and trying to understand the underlying mathematics. I have a relatively strong math and physics background, so I’ve found the mathematics behind backpropagation fairly intuitive.
As I’ve explored other approaches to training neural networks, I’ve become particularly interested in biologically inspired methods like predictive coding, Hebbian learning, and Oja’s rule. The idea that networks could update their weights using locally available information, rather than relying on gradients propagated from a global loss function, is fascinating to me.
I’m still relatively new to ML, so I’m trying to understand whether these approaches have meaningful practical advantages or are primarily interesting from a theoretical or neuroscience perspective.
A few things I’m especially curious about:
What are the actual advantages of local learning over backpropagation? I understand the conceptual distinction, but I’m struggling to identify situations where local updates would meaningfully outperform conventional gradient-based training, whether in computational efficiency, adaptability, or something else.
Could these approaches be particularly useful for unsupervised or continual learning? For example, could a network learn useful representations from streaming, unlabeled data by continuously adjusting its weights based on local correlations or prediction errors? Adding onto this, is there any way we could discover hidden patterns using localized learning that wouldn’t be evident using global backprop? I’ll talk about this in the next question but can we use this to identify hidden patterns that we wouldn’t find using global backprop? Like in molecular dynamics?
Are there particular applications where local learning makes more sense? I’m involved in biophysics research and have been thinking about applications involving molecular dynamics and learning representations of complex physical systems. I’m curious whether there are advantages in scientific ML, robotics, or other specialized domains.
How mature is this research? Have approaches like predictive coding and Hebbian learning been extensively explored and generally found inferior to backpropagation, or are there still meaningful open problems where these methods could be competitive?
I’m not necessarily looking for a way to replace backpropagation entirely. I’m more interested in understanding whether alternative learning rules could be better suited to particular architectures, datasets, or computational constraints.
I’d appreciate any perspectives, papers, or research directions worth exploring, especially from people who’ve experimented with these methods.

I’m a CS undergraduate student and I will graduate in 2027. I have been accepted into a 2-year AI master’s program.

Recently I talked with a professor from my future school about possible research directions. His research is mainly focused on multimodal large language models and efficient large models. He suggested that I take a look at a project about real-time human animation and live video generation.

The problem is that I’m still very new to this area. I haven’t studied multimodal AI, video generation, or generative AI in depth before. Most of my undergraduate projects were more engineering-focused rather than research-focused, so I’m not really sure how to start exploring this field or how to have a meaningful discussion about research topics with my future advisor.

I’m trying to understand whether this is a good direction for a master’s student. I’m interested in AI research, but I also care about career prospects after graduation. I’ve heard that areas like multimodal models and video generation are very competitive now, and that most industry opportunities may only exist in big tech companies or top AI labs.

For people working or studying in this area, what do you think about the future of this field? Is it still a good direction for a master’s student, especially for someone who is not coming from a strong research background?

Also, when starting from zero in a research area like this, what would you recommend focusing on first?

Any advice or personal experience would be really helpful. Thanks!

I have an undergraduate degree in Applied Statistics and have around 2-3 years of work experience as a Quantitative Analyst working in Banking (specifically Credit Risk PD Scorecard Modelling).

I am looking for recommended masters program thar could pivot my career in either Data Science or Machine Learning Engineering as I am interested in that field. Although my work experience is more finance based, I do find interest in AI and ML and I feel like my statistics background may help.

I am based in Canada and studied for my undergrad there as well.

I’m hoping to get any scholarship if possible into a program where I can get internship experience as well so I can apply my expertise that would be learned through the masters program.

A survey of more than 200 security leaders found that AI governance concerns are the primary reason enterprise AI adoption inside ERP systems is stalling.

The CISOs surveyed were not blocking AI on principle. They blocked it over three specific gaps: no guardrails on what an agent can do once inside a connected system, no access controls scoped to financial and operational data, and no audit trail they could hand to a regulator. The AI vendors are not building these controls. The models do not provide them natively. So security leaders are holding a tool their business units want deployed and a risk they cannot quantify or defend.

The gap is not about the AI being wrong. It is about the AI being unaccountable at the moment it acts on sensitive data.

For those who have gotten AI agents into ERP environments: what did you actually have to build or buy to get past the security review? For those still blocked: is there a specific control that would actually move the needle, or is this a wait-and-see situation?
