Research Reimplementations

Research · Proof of Deep Engineering

Each of these involves reading the original paper, implementing the core contribution, building something usable on top of it, and writing a blog post explaining what you learned. This combination — paper + implementation + product + writeup — is the research portfolio signal that opens doors to AI labs and frontier teams.

01
RAPTOR: Recursive Abstractive Processing for Tree-Organized Retrieval
Sarthi et al., Stanford · 2024 · arxiv:2401.18059
Standard RAG chunks documents linearly. RAPTOR clusters + recursively summarizes chunks into a tree — enabling queries at multiple abstraction levels. Dramatically outperforms naive RAG on multi-hop questions.
Build on top: Implement RAPTOR indexing over a large document corpus (legal cases, academic papers, product manuals). Compare retrieval quality with standard RAG using RAGAS. Add a UI showing the tree structure. Write a blog post with benchmarks.

Self-RAG: Learning to Retrieve, Generate, and Critique
Asai et al., UW · 2023 · arxiv:2310.11511
Instead of always retrieving, Self-RAG trains the model to decide when to retrieve and to critique its own outputs using special reflection tokens. Outperforms standard RAG by large margins on factual tasks.
Build on top: Replicate the inference loop (retrieval decision + critique tokens) using prompt engineering with a strong base model. Apply to a medical QA task. Measure hallucination rate vs standard RAG. Ship as a demo.

Gao et al., CMU · 2022 · arxiv:2212.10496
Instead of embedding the query directly, generate a hypothetical answer first, embed that, and use it for retrieval. Bridges the gap between query and document embedding spaces — especially for sparse queries.

Constitutional AI: Harmlessness from AI Feedback
Anthropic · 2022 · arxiv:2212.08073
CAI trains models to be helpful and harmless using a "constitution" of principles. The model critiques and revises its own outputs against these principles — removing the need for human labelers to flag harmful content.

LoRA freezes pretrained model weights and injects trainable rank decomposition matrices — reducing fine-tuning parameters by 10,000x with no inference latency penalty. This paper is how almost all fine-tuning is done today.
Build on top: Fine-tune a 7B model on a domain-specific dataset using LoRA (Hugging Face PEFT). Write a blog post explaining the math (rank decomposition, why it works). Benchmark: base vs LoRA vs full fine-tune on your eval set.
