Source audits & field notes
Machine Learning Algorithms: Mathematical Taxonomy and Bias-Variance Dynamics
A foundational source audit establishing the mathematical formulations, optimization landscapes, and bias-variance trade-offs of classical machine learning algorithms.
Engineering Production RAG Systems: An Architectural Delivery Roadmap
A technical source audit and systems roadmap for production RAG: structural ingestion, hybrid lexical-dense retrieval, reranking, and continuous eval gating.
CRAG Two Years On: The RAG Benchmark That Scores Silence Above a Wrong Answer
Meta’s CRAG re-read at arXiv v2 and its pinned repository: how the 1/0/−1 truthfulness score works, why plain RAG raised accuracy but cut truthfulness, and what KDD Cup changed.
The Production LLM Technology Stack: Architecture Patterns from Ingestion to Observability
A source audit analyzing the production LLM stack, evaluating data ingestion pipelines, vector indexing, serving engines, evaluation, and observability.
Parameter-Efficient Fine-Tuning: Architectural Mechanics of LoRA, QLoRA, and Variants
An architectural source audit of Parameter-Efficient Fine-Tuning (PEFT), deconstructing low-rank factorization in LoRA, LoRA-FA, VeRA, LoRA+, and QLoRA quantization.
AgentEval Architecture: Multi-Agent Utility Verification and Dynamic Rubrics
A source audit analyzing Microsoft’s AgentEval, evaluating CriticAgent, QuantifierAgent, and VerifierAgent dynamics for autonomous task validation.
Production Web Systems: The 10 Core Architectural Reliability Layers
An architectural audit of modern production web systems, decomposing the ten essential layers: edge routing, L7 ingress, caching, async events, and observability.
Meta CoPE Architecture: Contextual Position Encoding for Transformers
An architectural audit of Meta CoPE, analyzing dynamic position gating, fractional interpolation, subword abstraction, and attention scaling beyond rigid token indices.
The Archived Matryoshka Example Omits the Loss Wrapper
A bounded source audit finds plain-loss examples, post-encoding slicing, and a 384-versus-768 model substitution where the recipe trains nested prefixes.
