Many aspects of human reasoning, including language, require learning rules from very little data. Humans can do this, often learning systematic rules from veryfewexamples,andcombining theserulestoformcompositional rule-based systems.

Decision trees are widely used in many settings where interpretable models are preferred orrequired.

In this paper, we propose HyperLogic: a flexible approach leveraging hypernetworks to generate weights of the main network. HyperLogic can be combined with existing differentiable rule learning methods to generate diverse rule sets, each capable ofcapturing heterogeneous patterns indata.

The British skeleton team - among Team GB's best hopes for medals at the Winter Olympics - have been told their helmets do not meet safety standards only days out from the competition starting. The British team have appealed to the Court of Arbitration for sport (Cas) after the International Bobsleigh and Skeleton Federation (IBSF) said the helmets did not comply with the IBSF skeleton rules based on its shape. The British Bobsleigh and Skeleton Association (BBSA) said the helmet was designed with safety in mind. The team would currently not be able to wear the helmets in competition, but the Cas ruling will be heard on Thursday, with the result expected on Friday, before competition begins on 12 February. The British skeleton team enjoyed a successful 2024-25 season, with Matt Weston winning overall World Cup gold and Marcus Wyatt silver, winning all seven races between them.
