An ad hoc prompt works once, then quietly stops matching the result you got the first time. Claude Code Skills wrap the workflow in a SKILL.md file, with structured JSON for the data and Python for the parts that have to be deterministic.
On EMNIST Letters, a GMVAE reached 80% accuracy from roughly three labeled samples per cluster, where XGBoost needed 35 times the supervision. Most of that comes down to soft decoding instead of hard cluster assignment.
Google’s TurboQuant compresses the LLM KV cache 5x with near-zero accuracy loss. How PolarQuant’s randomized rotation flattens outliers, and how QJL residual correction keeps the attention dot product unbiased.
Bigger context payloads buy accuracy and charge you latency and tokens. How KNN-based prefiltering with scikit-learn trims an ICL payload without losing predictive accuracy, and whether to run it client side or service side.
AI slop is code that reads fine until it meets real traffic. This is the problem, hypothesis, test, conclusion loop I run on AI written WordPress and WooCommerce work, including a benchmark that settles metadata API versus a custom table.
Retrieval gets worse as the memory pool grows, while the confidence score keeps climbing. Here is what causes RAG memory decay and the four fixes I put into production systems: topic routing, semantic deduplication, relevance based eviction, and lexical reranking.
Recruiters now expect designers to ship production code out of AI agents. Here is what that costs in practice: toggles no screen reader can see, XSS holes in generated forms, duplicated code, and engineers spending more time per pull request cleaning up after it.
Basic embeddings only get you so far. Ahmad Wael explains the two-stage pattern behind advanced RAG retrieval: a bi-encoder for recall, a cross-encoder for precision, and the caching tricks that keep the second pass off most of your traffic.
Raw correlation makes campaigns look better than they were. Ahmad Wael walks through propensity score matching in Python: logistic regression for the scores, nearest neighbors for the pairs, and what happens to that 13% lift once selection bias is out of the way.
JPEG AI maps images into latent tensors, VVC targets up to half the bitrate of HEVC, and JPEG DNA stores pictures as biochemical sequences. What those standards change for anyone running WordPress at scale, plus a snippet for the new mime types.
