AI Papers of the Week
Every paper worth reading in AI, hand-picked one week at a time.

LLMs Represent Space and Time
MIT researchers find that LLMs internally encode linear representations of space and time across multiple scales.

Retrieval Meets Long-Context LLMs
NVIDIA's study comparing RAG and long-context LLMs, with the punchline that the two are complementary rather than substitutes.

StreamingLLM
MIT's StreamingLLM enables efficient streaming inference by preserving "attention sinks" - early-sequence tokens that most attention mass flows to.

Neural Developmental Programs (NDPs)
Proposes neural networks that self-assemble through a developmental process inspired by biological embryonic development.

The Dawn of LMMs (GPT-4V Deep Dive)
Microsoft's exhaustive 166-page analysis of GPT-4V's capabilities and limitations.

Training LLMs with Pause Tokens
CMU shows that adding a learnable `<pause>` token during both pretraining and fine-tuning gives the model extra "thinking time" and improves reasoning.

Self-Taught Optimizer (STOP)
Proposes recursively self-improving code generation where an LLM-scaffolded program improves itself.

RA-DIT (Retrieval-Augmented Dual Instruction Tuning)
Meta's RA-DIT is a lightweight recipe that retrofits LLMs with retrieval capabilities through dual fine-tuning.

KOSMOS-G
Microsoft's KOSMOS-G extends zero-shot image generation to multi-image vision-language input.

Analogical Prompting
Google's Analogical Prompting guides LLM reasoning by having the model self-generate relevant exemplars on the fly.

The Reversal Curse
Finds that LLMs trained on "A is B" fail to generalize to "B is A" - a surprisingly deep failure of learning.

Effective Long-Context Scaling (Meta)
Meta proposes a 70B long-context LLM that surpasses GPT-3.5-turbo-16k on long-context benchmarks.

Graph Neural Prompting (GNP)
A plug-and-play method that injects knowledge-graph information into frozen pretrained LLMs.

Vision Transformers Need Registers
Meta researchers identify artifact tokens in ViT feature maps and propose a trivial fix: add dedicated register tokens.

Boolformer
The first Transformer trained to perform end-to-end symbolic regression of Boolean functions.

LLaVA-RLHF
Adapts factually augmented RLHF to aligning large multimodal models, reducing hallucination without falling into reward-hacking pitfalls.

LLM Alignment Survey
A comprehensive survey of LLM alignment research spanning theoretical foundations to adversarial pressure.

Qwen
Alibaba releases the Qwen family of open LLMs with strong tool-use and planning capabilities for language agents.

MentaLLaMA
An open-source LLM family specialized for interpretable mental-health analysis on social media.

Logical Chain-of-Thought (LogiCoT)
A neurosymbolic framework that verifies and revises zero-shot CoT reasoning using symbolic-logic principles.

AlphaMissense
DeepMind's AlphaMissense is an AI model that classifies missense genetic variants as pathogenic or benign at genome scale.

Chain-of-Verification (CoVe)
Meta's Chain-of-Verification adds a "deliberation" step where the LLM fact-checks its own draft before finalizing.

Contrastive Decoding for Reasoning
Shows that contrastive decoding, a simple inference-time technique, substantially improves reasoning in large LLMs.

LongLoRA
An efficient LoRA-based fine-tuning recipe for extending LLM context windows without expensive full fine-tuning.
