Data Science Jobs

I need an end-to-end Retrieval-Augmented Generation platform, powered by Ollama-hosted language models, that lets a user drop in a document—TXT, PDF, or DOCX—then automatically searches my custom knowledge bases for exact matches and contextually related material, finally returning a concise, well-structured summary. Scope • Data ingestion: raw folders of text must be cleaned, chunked, embedded and stored in a vector store you recommend (Faiss, Milvus, or similar). • User workflow: drag-and-drop upload, progress feedback, and a chat-style window that displays the sourced passages beside the generated synopsis. • Retrieval logic: combine exact-match look-ups with semantic search so the AI can cite both literal hits and topic-level associations. • Age...

I need a full-stack AI solution that can analyse user behaviour on my website and serve accurate product recommendations in real time. The focus is strictly a product recommendation engine—think “Customers who viewed this item also liked…,” driven by collaborative and content-based filtering, reinforced with machine-learning techniques such as matrix factorisation or deep-learning embeddings where appropriate. Here is how I picture the engagement: • Model design and training: You will work with the historical purchase, click-stream and catalogue data I provide, choose the most suitable algorithms, handle data cleansing, feature engineering and model evaluations. And ving v v by • API or micro-service deployment: The trained model must run behind...

## Project Overview You will author a single terminal-based task and evaluate whether an AI coding agent can solve it end-to-end. Your goal is to design a task that is genuinely hard for frontier AI agents to solve, strictly verifiable, and resistant to shortcuts. The agent receives your instructions as its prompt, operates inside a Docker container with only shell tools, and writes its output to `/app/`. A deterministic `pytest` verifier then grades the run. > **CRITICAL WARNING:** You must write the prompt (``) yourself, in your own voice. Do not use AI to write or edit your instructions. The rubric heavily penalizes AI-generated instructions. You may use AI for everything else (coding, testing, etc.). Please don't send me automatic offers using Ai either. ## Deliverables Yo...

I have a historical lending dataset that requires a full end-to-end machine-learning workflow. First, I need thorough data preprocessing and exploratory analysis: identify and treat missing values, detect and cap or remove outliers, and inspect the class distribution. In this project the key concern is minority class under-representation, so any resampling or cost-sensitive approach you propose should directly address that imbalance. For feature engineering I want, at minimum, robust encoding of all categorical variables and consistent scaling or normalizing of the numeric fields before they enter the models. Feel free to add creative interactions if they genuinely improve recall without overfitting. Once the data pipeline is solid, train and compare several classification algorithms&mda...

Encryption computing knowledge which will allow us detect attackers

We’ve already built the platform. 106,000+ football matches. 48+ million odds movements. The statistical groundwork is complete. Now we need a different mind. We’re looking for someone who can study graphs, price behaviour and code as a language, not just as data. Someone who can group, deconstruct and reinterpret complex market behaviour to uncover hidden structures that conventional AI and statistical methods have missed. You must be an exceptional AI engineer, but more importantly, an exceptional thinker. If your instinct is to challenge assumptions, invent new ways of analysing behaviour, and see patterns that others overlook, we want to hear from you. Skills: * Python * AI / Machine Learning * Pattern Discovery * Graph & Behaviour Analysis * Representation Lear...

The statistical groundwork is finished: 106,000+ football matches and more than 48 million individual odds movements are already structured, cleaned, and sitting in Python-ready data stores. What I need now is a fresh layer of intelligence that can teach this data to speak—specifically, to surface the hidden structures that govern betting-market behaviour. We have all the ground work laid and there is no statistical obvious deviation that favors the bet placer ONLY the BOOKIE over 106K of matches - your suprised? We are NOT. The person we are looking for is not only a PYTHON engineer as the bookies will never unravel their software laid bare for the 100's thousands of python engineers to pick apart and profit from. NO - we are looking for a out of the box thinker that can scram...

I’m building a Python solution that automatically flags spam in my personal inbox. The pipeline should read raw message text, run it through classic NLP cleaning—then let a Naive Bayes model trained on TF-IDF features decide what is junk and what I actually want to see. I will be working exclusively with publicly available email corpora, so nothing proprietary needs to be handled. Key pre-processing I need implemented: • Tokenization • Stopwords removal • Stemming or lemmatization The stack is already chosen: Scikit-learn, Pandas and NumPy under Python. Once training is complete, I’d like a concise script or notebook that can: 1. Load a fresh batch of .eml or plaintext messages. 2. Output a CSV (or similar) labeling each as spam or ham. 3. R...

Please read the following instructions carefully before starting. 1. Sample Images The client has provided 10 sample images. Since all of the samples follow the same annotation standard, I have divided them among the team to save time. Your assigned sample image should be treated as the reference while annotating your assigned batch. 2. Requirements - Draw Polygon annotations for all required objects visible in the image. - Apply Key Segmentation only for Broad Leaf and Weed, exactly as demonstrated in the sample images. - Do not use any different annotation style. Follow the sample as closely as possible. 3. Annotation Quality - Polygon boundaries must be tight and accurate. - Do not include unnecessary background. - Cover the complete visible area of each object. - If multiple obj...
