In order to build more useful AI systems, a natural inclination is to try to make them more agentic . But while agents built from language models are touted as the next big advance [Wang et al., 2024],

Unsurprisingly, GNNs as MPNNs have been analyzed from multiple theoretical perspectives.

Probabilistic integral circuits (PICs) have been recently introduced as probabilistic models enjoying the key ingredient behind expressive generative models: continuous latent variables (L Vs). PICs are symbolic computational graphs defining continuous L V models as hierarchies of functions that are summed and multiplied together, or integrated over some L Vs. They are tractable if L Vs can be analytically integrated out, otherwise they can be approximated by tractable probabilistic circuits (PC) encoding a hierarchical numerical quadrature process, called QPCs. So far, only tree-shaped PICs have been explored, and training them via numerical quadrature requires memory-intensive processing at scale. In this paper, we address these issues, and present: (i) a pipeline for building DAG-shaped PICs out of arbitrary variable decompositions, (ii) a procedure for training PICs using tensorized circuit architectures, and (iii) neural functional sharing techniques to allow scalable training.

We propose two training-free context window extension methods via the lens of adjusting positional vectors, i.e., positional vector replacement and attention window extension.

Rishi Sunak has taken up senior part-time advisor roles at tech giant Microsoft and artificial intelligence start-up Anthropic. The former prime minister has been told he must not lobby ministers on behalf of the companies by the Advisory Committee on Business Appointments (Acoba), an independent watchdog which oversees the activities of former government figures. Sunak - who remains the MP for Richmond and Northallerton - will donate payments for the jobs to a charity he recently founded, the watchdog said. During his premiership, Sunak made tech regulation a significant priority, setting up an AI safety summit in 2023. In letters of advice sent to Sunak by Acoba and published on Thursday, his role at Microsoft was described as providing high-level strategic perspectives on geopolitical trends.
