Course Correcting Koopman Representations Accepted at #ICLR2024! We identify problems with unrolling in imagination and propose an unconventional, simple, yet effective solution: periodically "𝒓𝒆𝒆𝒏𝒄𝒐𝒅𝒊𝒏𝒈" the latent. 📄 arxiv.org/abs/2310.15386 @GoogleDeepMind 1/🧵

To extract rich, meaningful representations of a dynamical system, one can constrain the codes to be linearly spaced out in the latent space, \cite{Koopman}. This assumption gives rise to a model arch, resembling that of a linear RNN, with only one layer of recurrence. 2/

Why not get the best of both worlds by combining SSMs and Transformers? Excited to share our work at #NeurIPS2023: "Block-State Transformers." BST hits new highs in long-range language modeling and LRA tasks. paper: arxiv.org/abs/2306.09539 1/

Think of BST as a sequel to "Block-Recurrent Transformers." (arxiv.org/abs/2203.07852) In BRT, the transformer blocks talked to each other in a slow, sequential way, via recurrence. The catch? Blocks down the line had to wait their turn to process info. BST changes that game. 2/

to @iclr_conf reviewers who failed to acknowledge the rebuttals in time, 𝘁𝗵𝗲𝗿𝗲 𝗶𝘀 𝘀𝘁𝗶𝗹𝗹 𝘁𝗶𝗺𝗲. you can revise your review/score and include a post-rebuttal section. i know this is common knowledge but a friendly reminder never hurts. #iclr2024
