Transformer's runtime is quadratic with respect to the input sequence length, which makes training

The 197th Manchester derby takes place at Etihad Stadium on Sunday, but will it be the Blues or the Reds who claim the points - and local bragging rights? This is so hard to call, for many reasons, said BBC Sport football expert Chris Sutton. Manchester United could be buoyed by their win over Burnley before the international break, but I actually have bigger doubts about what we will see from Manchester City after seeing them capitulate the way they did against Brighton. Sutton is making predictions for all 380 Premier League games this season, against AI, BBC Sport readers and a variety of guests. For week four, he takes on Only The Poets frontman Tommy Longhurst. The Reading band are charging £1 a ticket when they play the O2 Academy Brixton, in February 2026.

For the best part of 15 years, every June I would get on a plane to Los Angeles to cover E3. It was the giant video games conference where most of the major games and consoles of the past few decades were first shown, from the PlayStation to the Wii U, Fallout 4 to Final Fantasy VII Remake. Alas, the pandemic killed E3, and so this year we have a cluster of loosely affiliated and competing events instead: Summer Game Fest, run by Geoff Keighley of the Game Awards; the Xbox Games Showcase; indie-driven event Day of the Devs and many more. It all kicks off tomorrow, 6 June. The Guardian's journalism is independent.

State space models (SSMs) have shown impressive results on tasks that require modeling long-range dependencies and efficiently scale to long sequences owing to their subquadratic runtime complexity. Originally designed for continuous signals, SSMs have shown superior performance on a plethora of tasks, in vision and audio; however, SSMs still lag Transformer performance in Language Modeling tasks. In this work, we propose a hybrid layer named Block-State Transformer (BST), that internally combines an SSM sublayer for long-range contextualization, and a Block Transformer sublayer for short-term representation of sequences. We study three different, and completely parallelizable, variants that integrate SSMs and block-wise attention. We show that our model outperforms similar Transformer-based architectures on language modeling perplexity and generalizes to longer sequences. In addition, the Block-State Transformer demonstrates more than tenfold increase in speed at the layer level compared to the Block-Recurrent Transformer when model parallelization is employed.

Abstract: Motivated by recent developments in optical switching and reconfigurable network design, we study dynamic binary search trees (BSTs) in the matching model. In the classical dynamic BST model, the cost of both link traversal and basic reconfiguration (rotation) is O(1). However, in the matching model, the BST is defined by two optical switches (that represent two matchings in an abstract way), and each switch (or matching) reconfiguration cost is α while a link traversal cost is still O(1). In this work, we propose Arithmetic BST (A-BST), a simple dynamic BST algorithm that is based on dynamic Shannon-Fano-Elias coding, and show that A-BST is statically optimal for sequences of length Ω(nαlogα) where n is the number of nodes (keys) in the tree. Abstract: The dynamic optimality conjecture, postulating the existence of an O(1)-competitive online algorithm for binary search trees (BSTs), is among the most fundamental open problems in dynamic data structures.
