Met police in talks to buy Palantir AI tech for use in criminal investigations
Scotland Yard is understood to be moving quickly towards embracing AI automation in its intelligence units. Scotland Yard is understood to be moving quickly towards embracing AI automation in its intelligence units. The Metropolitan police has held talks with Palantir that could lead to the London force buying the US spy-tech company's AI technology to automate intelligence analysis for criminal investigations, the Guardian has learned. Palantir, whose software is used by Donald Trump's ICE immigration enforcement programme and the Israeli military, demonstrated its systems to senior officers in the intelligence division at the UK's largest police force last month. Intelligence staff have been tasked with finding intelligence systems that AI could automate to increase productivity.

SPALS: Fast Alternating Least Squares via Implicit Leverage Scores Sampling
Dehua Cheng, Richard Peng, Yan Liu, Ioakeim Perros
Tensor CANDECOMP/PARAFAC (CP) decomposition is a powerful but computationally challenging tool in modern data analytics. In this paper, we show ways of sampling intermediate steps of alternating minimization algorithms for computing low rank tensor CP decompositions, leading to the sparse alternating least squares (SPALS) method. Specifically, we sample the Khatri-Rao product, which arises as an intermediate object during the iterations of alternating least squares. This product captures the interactions between different tensor modes, and form the main computational bottleneck for solving many tensor related tasks. By exploiting the spectral structures of the matrix Khatri-Rao product, we provide efficient access to its statistical leverage scores. When applied to the tensor CP decomposition, our method leads to the first algorithm that runs in sublinear time per-iteration and approximates the output of deterministic alternating least squares algorithms.
