Activist Palliser takes stake in toilet maker Toto in AI play

The Japan Times

Activist fund Palliser Capital has taken a stake in Japanese washlet maker Toto, and is urging the company to boost promotion of its little-known chip parts business. Activist fund Palliser Capital has taken a stake in Japanese washlet maker Toto and is pushing the firm to ramp up promotion of its little-known chip parts business in a bid to unlock value from the artificial intelligence boom. The U.K.-based fund sent a letter to Toto's board last week calling for more disclosure about its advanced ceramics segment. The segment produces electrostatic chucks used in the manufacturing of NAND memory chips, and Palliser views the toilet maker as "the most undervalued and overlooked AI memory beneficiary," the documents show. A representative for Toto declined to comment. Insatiable demand for AI infrastructure has sent memory prices skyrocketing in recent months, boosting shares of chipmakers such as Kioxia Holdings to record highs.


Kernel Quadrature with Randomly Pivoted Cholesky Ethan N. Epperly and Elvira Moreno

Neural Information Processing Systems

This paper presents new quadrature rules for functions in a reproducing kernel Hilbert space using nodes drawn by a sampling algorithm known as randomly pivoted Cholesky. The resulting computational procedure compares favorably to previous kernel quadrature methods, which either achieve low accuracy or require solving a computationally challenging sampling problem.



Testing Semantic Importance via Betting

Neural Information Processing Systems

Providing guarantees on the decision-making processes of autonomous systems, often based on complex black-box machine learning models, is paramount for their safe deployment. This need motivates efforts towards responsible artificial intelligence, which broadly entails questions of reliability, robustness, fairness, and interpretability.
