🎧Understand Audio Embeddings
Stop forcing audio through text. Drops show the audio-native path — wav2vec, CLAP, MERT — and when it beats transcribe-then-embed for music search, speaker ID, and sound classification. By the end you can plan a 'find similar drums' search over a sample library.
🧭Understand ANN Algorithms: HNSW, IVF, PQ
Stop tuning ef and M by trial and error — see HNSW, IVF, and PQ as physical structures (a multilayer skip graph, a coarse cluster index, and a vector compressor) so you can predict which one fits a 100M-vector workload before you benchmark anything.
🧬Sentence vs Token Embeddings
Stop grabbing BERT's [CLS] token and calling it a sentence embedding. By the end you'll know exactly when token, pooled, and contrastively-trained vectors each win — and design a 100K-doc semantic search you can defend.
📝Generate Commit Messages with AI
Stop letting your git history decay into 'fix stuff' two weeks after you adopt Conventional Commits. By the end you'll have an AI commit hook reading your diff and producing a compliant message every time — and a team convention doc that makes it stick.
📉Detect Drift in LLM and ML Apps
Stop confusing 'data drift' and 'concept drift' — they need different fixes. Walk one feature through both kinds of drift on a real-shaped dataset, then design a drift dashboard for an LLM app where ground truth is delayed by 7 days.
🗺️Choose an LLM Deployment Topology
Stop choosing between 'just call OpenAI' and 'self-host on H100s' — there are four real LLM topologies in between. By the end you can sketch a 12-month plan that survives 10x traffic growth.
🌫️Build Intuition for Diffusion Models
Stop reading 'noise to image' as magic and start seeing it as a learned vector field that pulls samples toward the data. By the end you can sketch one denoising step and explain how classifier-free guidance bends the field toward 'a cat in a hat.'
🔬Build an LLM Eval Harness for Production
Stop running eval notebooks once and forgetting them. Build a three-layer harness — pre-merge CI, pre-deploy gate, online sampling — with the right cadence, budget, and judge calibration for a production RAG app.
⚖️Audit AI Models for Bias
Three fairness metrics. One model. They disagree. Walk a synthetic loan classifier through demographic parity, equalized odds, and calibration; see where they conflict; then outline a regulator-defensible audit plan for a resume screener.
🚦Version and A/B Test Prompts in Production
Stop shipping prompt edits like config tweaks and start treating them like code with versions, canaries, and kill switches. By the end you can write a one-page rollout plan with success criteria, sample size, and a rollback trigger that someone else could execute.
🧾Use Vision-Language Models for OCR and Document Extraction
Stop gluing Tesseract to brittle regex parsers. Design VLM-based document extraction pipelines that return typed JSON with confidence scores — and know exactly when classical OCR still wins on cost.
🧪Use AI to Generate Tests
Turn AI from a happy-path test generator into a real partner that probes boundaries, error paths, and oracle gaps — so the suite catches bugs instead of memorizing them.
📊Use AI for Spreadsheet Workflows
Stop pasting your sheet into ChatGPT and hoping. Learn four reusable patterns — formula generation, bulk row processing, cleanup, summary — that keep your spreadsheet as the source of truth and let you ship a workflow that cleans, classifies, and summarizes a 200-row dataset.
📝Use AI for Meeting Notes That You'll Actually Read
Stop treating AI meeting notes as a dumping ground nobody reads. Build a per-meeting-type workflow that ends in shared decisions and assigned actions — not another inbox full of ignored summaries.
🔍Use AI for Code Review
Stop accepting every AI review comment uncritically — and stop ignoring them all. By the end you'll know exactly what AI catches reliably, what it misses, and how to write a review prompt your team actually trusts.
🖼️Understand Vision Transformers (ViT)
Walk one 224x224 image through patching, embedding, and attention until ViT stops feeling like a magic trick — then predict where the heads attend on a cat-and-person photo before the demo confirms it.
🔊Understand Text-to-Speech Quality Dimensions
Build a five-axis TTS scorecard — naturalness, prosody, latency, consistency, controllability — that replaces demo-vibe-checks with a defensible audit you can take into any voice-agent vendor meeting.
✂️Understand Image Segmentation with SAM
Separate semantic, instance, and promptable segmentation so you can pick the right tool — then plan a tiny SAM-powered pipeline that crops product photos for an ecommerce catalog before you write a line of code.
📡Stream LLM Responses for Snappy UX
Stop shipping six-second blank screens — switch to SSE streaming and watch perceived latency collapse from seconds to milliseconds. By the end you'll add a stop button and graceful retry to a streamed chat without dropping tokens.
📉PCA: Dimensionality Reduction from Eigenvectors
Connect PCA to the eigenvectors of the covariance matrix, then compress a 50-feature dataset to 5 components and defend exactly how much information you kept.
💰Optimize Cost in LLM Applications
Stop watching your LLM bill scale linearly with traffic. By the end you can take any feature, name three cost cuts with dollar estimates, and defend the tradeoffs to your team.
🎨Master Text-to-Image Prompt Craft
Build an internal recipe for prompting diffusion models — subject, medium, style, lighting, weight, negative — so you can generate brand-aligned images on demand instead of copying random prompts from marketplaces.
🔭Learn LLM Observability Fundamentals
Stop finding out about LLM regressions from angry user emails. By the end you'll know what to log on every call, which tools fit which signal, and how to sketch one dashboard an on-call engineer can read at 3am.
🧱Get Structured Output with Pydantic and JSON Schema
Replace markdown-fenced near-JSON and regex band-aids with a Pydantic schema the API enforces for you. By the end you can convert any ad-hoc prompt to typed output and measure how many parse failures you just deleted.
