Indonesian soldiers jailed for up to 3 years over ‘arrogant’ acid attack on activist
Four Indonesian soldiers found guilty of an acid attack that left an activist blind in one eye were sentenced on Wednesday to up to three years in prison by a military court, with a judge calling their actions “arrogant”. The four, all members of the military’s Strategic Intelligence Agency (BAIS), were found guilty of premeditated assault for the attack in March that left Andrie Yunus, 27, blind in one eye. They were arrested shortly after the attack, and BAIS head Yudi Abrimantyo stepped...
Tree-Guided Identify-Then-Exploit: A Unified Framework of Best Arm Identification and Regret Minimization for Dueling Bandits
arXiv:2606.01799v1 Announce Type: new Abstract: We study $N$-armed stochastic dueling bandits under the Condorcet-winner assumption, where three widely adopted objectives are considered: best-arm identification (BAI), weak regret, and strong regret. We propose Tree-Guided Identify-Then-Exploit (TG-ITE), the first unified framework to tackle all these objectives to our knowledge. Without requiring stronger assumptions, we propose a shared tree-guided identification approach to find a...
Sat-Chi, fresh off Singapore Open win, pull out of Indonesia Open
India’s star men’s doubles pair, Satwiksairaj Rankireddy and Chirag Shetty, have pulled out of the Indonesia Open 2026 after Satwik suffered an injury during their opening-round match in Jakarta. The duo was forced to retire midway through their contest against Malaysia’s Aaron Tai and Kang Khai Xing on Wednesday, bringing an early end to their campaign. The Badminton Association of India (BAI) later confirmed the withdrawal and said the pair would now focus on recovery before returning to...
Fixed Budget is No Harder Than Fixed Confidence in Best-Arm Identification up to Logarithmic Factors
arXiv:2602.03972v3 Announce Type: replace-cross Abstract: The best-arm identification (BAI) problem is one of the most fundamental problems in interactive machine learning, which has two flavors: the fixed-budget setting (FB) and the fixed-confidence setting (FC). For $K$-armed bandits with a unique best arm, the optimal sample complexities for both settings have been settled down, and they match up to logarithmic factors. This prompts an interesting research question about the generic,...
Two-Fidelity Best-Action Identification for Stochastic Minimax Tree
Announce Type: new Abstract: We study fixed-confidence best-action identification (BAI) in stochastic minimax trees. This problem is increasingly relevant in modern AI planning, where deep minimax search and Monte Carlo Tree Search (MCTS) with language model long rollouts face a fundamental tradeoff: heuristic evaluations are cheap but biased, while accurate rollouts are reliable but prohibitively expensive. We propose 2FFS, a two-fidelity tree-search algorithm that brings multi-fidelity...
Best-Arm Identification-Based Trust Region Selection for Bayesian Optimization on Multimodal Functions
arXiv:2605.31050v1 Announce Type: new Abstract: Gaussian process-based Bayesian optimization (BO) is a popular approach for expensive black-box optimization, but its performance often degrades on complex multimodal or high-dimensional problems. Trust region-based BO mitigates this issue by focusing on local regions, and recent studies suggest that selecting an effective region can be formulated as a multi-armed bandit problem. We propose a trajectory-aware framework that integrates best-arm...

Indonesian military court jails four soldiers over acid attack on activist
Indonesian military court jails four soldiers over acid attack on activist The soldiers from the military's Strategic Intelligence Agency were sentenced to between one-and-a-half and three years in prison for the attack in March that left Andrie Yunus blind in one eye. Four Indonesian soldiers found guilty of an acid attack that left an activist blind in one eye were sentenced on Wednesday (Jun 10) to up to three years in prison by a military court, with a judge calling their actions...
In situ nanocrystal confinement for efficient blue perovskite LEDs
Abstract Metal halide perovskites have emerged as promising semiconductors for light-emitting diodes (LEDs) owing to their excellent luminescence properties1. However, their performance remains limited, primarily owing to the inherent contradiction between ‘high crystallinity’ and ‘small size’ in the in situ synthesis of perovskite nanocrystals on substrates. Here we report efficient blue perovskite LEDs (PeLEDs) achieved via in situ polymerization-driven nanocrystal confinement to...
Acid attack victim's lawyer describes trial of perpetrators as a 'sham'
Lawyer of Indonesian man attacked with acid says trial of perpetrators is a 'sham' Sat 6 Jun 2026 at 4:55am At 11pm on a humid Jakarta night in March, human rights activist Andrie Yunus was getting ready to head home after finishing a recording for a podcast. This story contains details of an assault. The episode, which had been taped at a legal aid office in central Jakarta, was on the increasing influence of the military across Indonesia's civilian institutions, an issue the 27-year-old...
