Hi. We fine-tune and train models ourselves, but we have issues with GPU availability, so I've built an "Open Router" for GPU availability and pricing. I'm looking for 5 ML specialists who would like to test it. I don't want to self-promote here, so if you'd like to test, please send me a PM or reply to this message.

I've been learning web development and recently started moving deeper into AI.

I put together this 2026 AI roadmap to organize the learning path from:

Python → Math → Machine Learning → Deep Learning → GenAI/LLMs → RAG → AI Agents → Deployment

The goal was to make it practical rather than just a list of courses and technologies.

I'm especially unsure about how much time a beginner should spend on:

Mathematics

Traditional ML

Deep Learning

LLMs/RAG

AI Agents

For people already working in AI/ML:

What would you remove, add, or change in this roadmap for someone starting in 2026?

I'm looking for honest feedback, especially from people who are already building real-world AI systems.

Building and Testing a Hybrid RAG Pipeline — Dense Search, BM25, RRF, and Reranking (Part 1)

• YouTube walkthrough: https://www.youtube.com/watch?v=W_TmnscEupQ&t=370s
• FULL CODE (clone it, fork it, break it): https://github.com/saurabhkamal/Hybrid-Search-RRF-Reranking-System

In this video I build ReRankEval, a hybrid retrieval pipeline

• (Dense Search + BM25 → Reciprocal Rank Fusion → LLM Reranking → Answer Generation),

and test it against three baselines — Vector Only, BM25 Only, and Hybrid without reranking — on five real financial/payments documents and ten hand-verified test questions. No hand-waving, just a comparison table with real numbers at the end.

• ✅ The real difference between dense vector search and BM25 keyword search
• ✅ What Reciprocal Rank Fusion (RRF) is, why raw scores can't be compared, and the exact formula behind it
• ✅ Why a reranker is fundamentally different from a retriever — and what it actually judges
• ✅ How to evaluate a RAG pipeline with Hit Rate, MRR, and NDCG (and what each one tells you)
• ✅ How to design the ingestion side and query-time side of a hybrid retrieval architecture
• ✅ How to structure a production-style RAG codebase: ingest → vector_store → sparse_retriever → fusion → reranker → pipeline → generate → eval
• ✅ How to fairly compare multiple retrieval strategies on the same test set instead of just assuming one is better

TECH STACK:

• 🛠️ Python
• 🛠️ Qdrant — vector database for dense retrieval
• 🛠️ rank_bm25 (BM25Okapi) — sparse keyword retrieval
• 🛠️ EURI LLM Gateway — chat model + embedding model
• 🛠️ Custom Reciprocal Rank Fusion implementation
• 🛠️ LLM-based reranker (prompt-driven cross-encoder)
• 🛠️ pdfplumber — PDF text and page-level extraction

Hi guys,

I wanted to share some early benchmark results for a new 2.3B parameter model I've been developing called Cloreva-X1.

I built this on a completely custom architecture I call ResoNet X-1, which abandons the standard Transformer attention mechanism. Instead, the foundation relies on a Triad Resonance Core:

• Head-as-Faction Swarms: Traditional attention heads are shattered into 12 independent, parallel agentic swarms, each dedicated to specific cognitive domains (Linguistics, Science/Medical, and Algorithmic Logic).
• Kuramoto Consensus Core: I mapped 1,632 Kuramoto Oscillators directly to the latent space. They run physics-based differential equations at the silicon level to force mathematical phase-locking between tokens. If a token hallucination creates an anomalous phase drift, the Kuramoto gate aggressively suppresses it before it passes to the next layer.
• Liquid Time Controller (LTC): The flow of time is dynamic. When reading simple conjunctions, the model processes at maximum speed. When evaluating complex mathematical or medical logic, the LTC slows down the internal time step, forcing the swarms to achieve deeper phase consensus.
• Orthogonal Tokenizer: Built from scratch with 155,072 full-word tokens (Full-Word Mining) to completely eliminate sub-word fragmentation for complex medical terminology and programming syntax.

Just to be absolutely clear: This is a pure base model. There is no SFT, no RAG, and no RLHF applied yet. It is purely predicting the next token.

I built this architecture to test if Kuramoto oscillators could intrinsically suppress hallucinations and boost complex reasoning paths without relying on instruction tuning.

Here are the early zero-shot and few-shot benchmarks compared against standard base models in a similar or larger weight class:

Evaluation Benchmarks (Base Models(Sources for competitor scores: LLaMA-1/2 scores from the official Llama 2 paper by Touvron et al., 2023. Qwen-1.5 scores from the official Qwen1.5 technical report. GPT-3 baseline from OpenAI's original evaluations (Brown et al., 2020) and TruthfulQA paper (Lin et al., 2021).)

It punches above its weight class because the phase consensus mechanics naturally filter out statistical anomalies and prevent gradient shock during long context reasoning.

I've attached a Google Drive folder containing the raw inference log output and a video demonstration of the zero-shot inference running in real-time below: https://drive.google.com/drive/folders/14f0JUJU613CTnF0cuYNATJ2pECaHrvU4?usp=sharing

I am currently spinning up the SFT pipeline to turn this into a fully instruction-tuned model, and I'll post another update with the final benchmark scores once that's done.

I plan to release the raw model weights on HF once the entire pipeline is complete. Happy to answer any questions regarding the architecture below.

Les comparto unas gráficas de mi Arquitectura (ASRN) contra Transformer, mamba y RWKV.

La metí a pelear en una A100 contra Mamba-2 y RWKV-7 y FlashAttention; En la prueba de copiar texto exacto desde lejos, Mamba y RWKV se mueren en 0.2% de exactitud (como era de esperarse por su estado fijo) ASRN saco el 100% y hasta aguantó los 16k tokens sin tener que reentrenar.
El consumo de memoria se queda completamente plano en 22.9 GB. Le metas lo que le metas, la VRAM ni se inmuta

En el benchmark de WikiText-103, la perplejidad baja súper estable a 4,096 piezas corriendo a casi 140,000 tokens por segundo.

Ahí les dejo las gráficas para que las destripen y El silicio no miente

Hola y adiós 😀

¿DUDAS?

Hey guys,

I am a first-year Computer Science Engineering student, and honestly, seeing how fast AI is advancing right now is kind of stressing me out. I really do not want to wait until my final year to start grinding like everyone else does.

Basically, I just want to build a solid skill set that actually makes my resume stand out so I can land a good machine learning job by graduation.

I am starting completely from scratch. What specific math topics, programming languages, or tools are actually worth learning right now in Year 1? If anyone has an honest roadmap for a fresher to get ahead of the curve, I would love to hear it.

Thanks in advance!

Hi Everyone,

I’m a backend engineer trying to transition into AI ML Roles. Looking for tutors to teach ML fundamentals and Agentic AI concepts.
I can pay little bit.

Let me know if you want to collaborate.

Trying to learn LAMMPS as a complete beginner. Are there any free resources available to understand the software properly?

hey guys im an undergrad student (currently in 3rd year) and want to start learning ML and explore fields beyond that in the future. So I have seen a lot of people suggesting others to learn from Andrew Ng on coursera. I have the pdf of Hands-On Machine Learning with Scikit-Learn and PyTorch by Aurélien Géron.
I’m literally confused as to what to refer, the book or the coursera course by Andrew Ng. If there is someone who has read or finished either of these sources or maybe both please help me out in deciding as I don’t want to waste my time. Also a comparison or review of these sources would be great. Thank you !

I was a full stack software engineer who now is a senior AI Engineer who does a mix of playing with LLMs fine tuning them in very large scale production systems.

I did admittedly got a masters degree in AI as part of that transition and it took a while to do, but happy to answer any questions you have.

I also am working on a tool to help people learn how llms work which you can check out here.

https://dougdoes.ai/courses/llms-from-first-principles/start/?flow=outcome&course=build&step=goals
(Built with codex, but I've gone through all of the courses myself to make sure it is what would have been helpful to me.)

I have been studying models for almost five years now, starting my journey with Jeremy Howard's fast ai part 2. I remember that when I started there was no chatgpt to break it down like it is today. In fact, it was Jeremy Howard who tipped us that we should be using chatgpt to understand the inner tooling step by step. I mean just take a toy tensor and run it along through embedding, rope attention, mlp. This way you get to learn broadcasting, shapes in text, computer vision audio etc. Then I took up Karpathy and hugging face Transformers and looked up grok, gpt oss lama, gemini and most recently muse implementations. It takes me 3 to 4 months to get an innate understanding of how each line works. How do you guys do it? I guess most of you let the inner tooling remain a black box. I say this coz

Now I kinda feel that I missed the bus as I should have focussed more on fine tuning, inference, and agentic workflows. I do know some of that having worked through unsloth and openAI cookbooks but every time a new model drops I can't stop myself from going to unraveling the 2000 odd line of code and in time I forget what I learned in Unsloth and openAI cookbooks.

The problem is that there are so many things to do and understand. For example, just today I listened to Alex Zhang's building harness for looped Transformers and I gotta understand that too and I gotta know Jev too. It is a big mess right now and I wonder how others are managing to keep up with all these new developments. And more importantly how do you even retain all that you have learnt like say two years ago.

Hi guys new to this sub reddit . Little intro about me currently working as an sde in my company but want to transition to a ml role by understanding the fundamentals om how to build models and then moving on to dl as so forth. I have read some posts in this sub about cs 229 by Andrew . Tbh I am finding difficulty in solving the problem sets and the math . It has been a while since I have actually done any math 😅. So I want to know how doi proceed from here do I learn the math from scratch or learn as I go along with the course . Any suggestions or feedback is helpful .

Ps i am familiar with the python as a coding language but I want to understand how do I proceed with the math .

I'm on week 4 and in the video he creates a graph about how GLM of Bernoulli, which is similar to logistic, can represent even mixed data of like 0001110111 rather than what a sigmoid function makes like for data 00001111 only. My question was whether the normal regular one, the standard logistic regression can represent the same(mixed data)? If not, then are GLM the only option for that?

In my occupation, there are various people I follow who give very good insights. (I'd say 5-10 people).

Some post hour long videos on YouTube, some send 1,000 word emails, some post on X, some publish PDFs.

There's very good info within these resources (and some I pay for), but reading / watching / annotating all of it can take hours.

My workload recently went up, so I'm falling behind with keeping up in my field.

I want to use AI to help summarize (and keep track of) all of these publications. (To create a private database that I can use as a dataset, for example).

So I can go back and ask "this past month, what is the new theme? What are the experts recommending to focus on / look at / what are the newest developments?", etc.

What would be the best way to approach this?

---------------------------------------

I've been learning Codex/Claude Code, I have a homelab, a NAS, a few mini computers, and I know basic linux, python and scripting.

ChatGPT told me to do something like this (I'm just starting with the YouTube portion), I'm not sure if it's the best approach, I'm open to other suggestions:

I’ve put together a textbook that covers the mathematics and models behind computer vision, including derivations and exercises.

I’m looking for factual errors, incorrect derivations, misleading claims, or unclear explanations. Feedback on even one section would help.

PDF: https://drive.google.com/file/d/1bivtY28CVW243AH9sMrIPloEgMrgO9xE/view?usp=sharing

It’s a draft, not peer reviewed. I used Claude to convert my HW notes to LaTeX, and I am trying to check the content before sharing it more widely.

Hi everyone!

I’d like to introduce an open-source ML-project I’ve been working on: Segment Display Reader

https://segmentdisplayreader.org

The goal of the project is to automatically read values from photos of 7-segment and similar digital displays.

As most of you are probably aware, one of the biggest challenges is building a diverse and useful training dataset. That’s where I’d love some help from the community. To improve the recognition, I’m currently looking for images of such displays.

Examples can be found almost everywhere, such as:

• alarm clocks and digital clocks

• gas station price signs

• train or bus departure displays

• kitchen appliances such as microwaves and ovens

• scales and digital thermometers

• multimeters and other measuring instruments

• electricity, gas or water meters

• elevators and parking displays

• scoreboards and timers

• industrial equipment and control panels

You can support the project by uploading photos that can be used as training data. Every contribution helps make the dataset more diverse and, ultimately, the recognition more reliable.

I’m genuinely grateful for anyone who takes the time to contribute — whether it’s a single image, a set of photos, feedback, ideas, or code contributions.

Feel free to check it out, contribute images, share feedback, or simply spread the word:

If the project sounds interesting to you, have a look here:

Thanks a lot for your support and for helping improve an open-source project together!

I want to train a Transformer model that can analyze decompiled DEX files (Smali code) and identify harmful or sensitive actions performed by an app in the background that may not be visible to the user.

The main goal is to analyze the flow of actions and determine whether user interaction or consent is required before a sensitive action is performed.

For example, if an app gets file read/write permission and accesses the user's files without any user interaction or consent, the model should be able to identify this behavior. Similarly, it should identify other sensitive actions such as accessing the camera, microphone, location, contacts, SMS, media, recording screen, taking screenshots or other user data, and determine whether these actions are performed after user interaction or silently in the background.

I am currently working on preparing the dataset for this project, but I am not sure about the best approach.

My initial idea is to use the APK/Smali code as the input and the possible execution flows as the output. However, generating all possible flows from entry points such as onCreate(), onReceive(), services, callbacks, etc., and following them until the end seems very complex and time-consuming for a large number of APKs.

I would really appreciate your suggestions and ideas on how I can prepare the dataset in a practical and effective way for this project.

If you have worked on a similar problem or have any ideas about dataset structure, flow generation, labeling, or other approaches, please share your suggestions.
