Weekly Paper Notes — one of the top picks from the 2026-06-06 CS paper digest. Area: AI / ML. Authors: Akarsh Kumar, Phillip Isola (MIT) arXiv: 2606.06479 · PDF TL;DR This paper proposes Supervised Memory Training (SMT), a way to pretrain nonlinear RNNs without ever doing backpropagation through time (BPTT). The trick: replace recurrent credit assignment with a supervised problem over memory transitions. A Transformer-based “memory encoder” is first trained with a predictive-state objective — it learns a representation m_t that retains exactly the information about the past needed to predict the future....

Weekly Paper Notes — one of the top picks from the 2026-06-06 CS paper digest. Area: NLP / Systems-for-ML. Authors: Yutao Sun, Yanqi Zhang, Li Dong, et al. (Microsoft Research Asia) arXiv: 2606.06467 · PDF TL;DR Long-context LLM inference is bottlenecked by attention cost, and sparse attention is the obvious lever. The two existing families both disappoint in practice: block-sparse patterns (sliding window, dilated, etc.) give clean speedups but lose quality, while token-sparse patterns (top-k over the KV cache) preserve quality but spend most of the budget deciding which tokens to attend to — the routing itself becomes the bottleneck....

Weekly Paper Notes — Seminal Paper of the Week for May 24–30, 2026. After a multi-week streak of systems classics (Raft, MapReduce, Lamport, ARIES), this week rotates to AI / ML. Authors: Ashish Vaswani, Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan N. Gomez, Łukasz Kaiser, Illia Polosukhin (Google Brain / Google Research / University of Toronto) Venue: NeurIPS 2017 arXiv: 1706.03762 · PDF Why this paper Picking Attention Is All You Need as a Seminal Paper of the Week in 2026 feels almost too on-the-nose — the Transformer is the architectural substrate underneath every frontier LLM, every modern diffusion model, every state-of-the-art protein folding system, every reasoning model whose chain-of-thought you have ever read....

Weekly Paper Notes — one of the top picks from the May 24–30, 2026 CS paper digest. Area: NLP / Theory. Authors: Jon Kleinberg, Anay Mehrotra, Amin Saberi (Cornell / Yale / Stanford) arXiv: 2605.30324 · PDF TL;DR A line of theoretical work asks: given examples from an unknown target language drawn from a known countable collection, can a learner eventually output only new valid strings from that language? Prior results — including Kleinberg & Mullainathan’s 2024 paper that triggered the modern wave — assume the learner remembers the entire example history....

Weekly Paper Notes — one of the top picks from the May 24–30, 2026 CS paper digest. Area: AI / ML. Authors: Lukas Aichberger, Sepp Hochreiter (JKU Linz / NXAI) arXiv: 2605.30343 · PDF TL;DR Modern reasoning LLMs scale test-time compute by emitting long chains of thought — but every “thought token” is forced to round-trip through the autoregressive decoder, conflating internal computation with external communication. Reasoning in Memory (RiM) instead inserts blocks of fixed special tokens that act as scratch space for the model’s working memory....

Weekly Paper Notes — one of the top picks from the May 17–23, 2026 CS paper digest. Area: AI / ML. Authors: Ali Hatamizadeh, Yejin Choi, Jan Kautz (NVIDIA) arXiv: 2605.22791 · PDF · Code TL;DR Linear-attention models compress an unbounded history into a fixed-size recurrent state, but their active edit — the operation that overwrites stale associations with new ones — has historically been controlled by a single scalar gate that decides both how much old content to erase and how much new content to write....
