Data Science Tutorials

Learn what a residual plot is, how to interpret common patterns, and how residual plots help identify nonlinearity, heteroscedasticity, outliers, and other regression problems.

A practical, math-first look at saddle points - what makes them different from local minima and maxima, how to spot one using gradients and the Hessian, and why they show up so often in high-dimensional optimization and neural network training.

Learn what an augmented matrix is, how it represents systems of equations, and how to use row operations to solve them.

Reduce token usage by cutting context bloat, terminal noise, verbose responses, and over-engineered code with lightweight tools that optimize coding-agent workflows automatically.

Learn how to organize tasks by category using Node.js and MongoDB. Build a REST API with create, list, get, update, delete endpoints and category filter.

Self-supervised learning trains models to pull their own supervision from unlabeled text, images, audio, and video, using techniques like contrastive learning, masked modeling, and autoregressive prediction to build the representations behind today's language, vision, and multimodal models.

Set up Muse Spark 1.3 in Muse Code and the Meta Model API, choose between the contributor and standard tiers, and see whether Meta's efficiency claims hold.

Learn how to use the Gemini 3.8 Flash API in Python: Interactions API setup, thinking_level tuning, PDF-to-JSON extraction, and function calling with code.

Use GPT-6 Astra via the OpenAI API to build a Python release check agent with async tools, reasoning controls, Structured Outputs, and cost tracking, then test computer use and steering.

Learn how to build a custom AI agent harness with Python, ReAct loops, and durable state.

Learn how to use Anthropic’s latest flagship model to build a Python agent that reads a Flask repository before planning a change. Add progress updates, read-only file tools, and cost controls.

Use Unsloth Desktop for local AI workflows, including LLM inference, fine-tuning, vision models, image and video generation, OpenCode coding agents, and local APIs from one desktop application.
