A Review of Statistical and Machine Learning Approaches for Coral Bleaching Assessment

arXiv.org Machine Learning

Coral bleaching is a major concern for marine ecosystems; more than half of the world's coral reefs have either bleached or died over the past three decades. Increasing sea surface temperatures, along with various spatiotemporal environmental factors, are considered the primary reasons behind coral bleaching. The statistical and machine learning communities have focused on multiple aspects of the environment in detail. However, the literature on various stochastic modeling approaches for assessing coral bleaching is extremely scarce. Data-driven strategies are crucial for effective reef management, and this review article provides an overview of existing statistical and machine learning methods for assessing coral bleaching. Statistical frameworks, including simple regression models, generalized linear models, generalized additive models, Bayesian regression models, spatiotemporal models, and resilience indicators, such as Fisher's Information and Variance Index, are commonly used to explore how different environmental stressors influence coral bleaching. On the other hand, machine learning methods, including random forests, decision trees, support vector machines, and spatial operators, are more popular for detecting nonlinear relationships, analyzing high-dimensional data, and allowing integration of heterogeneous data from diverse sources. In addition to summarizing these models, we also discuss potential data-driven future research directions, with a focus on constructing statistical and machine learning models in specific contexts related to coral bleaching.


Google planning powerful AI data center on tiny Australian outpost

The Japan Times

Red crabs walk across a road in Christmas Island, Australia, in October. SYDNEY - Google plans to build a large artificial intelligence data center on Australia's remote Indian Ocean outpost of Christmas Island after signing a cloud deal with the Department of Defence earlier this year, according to documents and interviews with officials. Plans for the data center on the tiny island located 350 kilometers south of Indonesia have not previously been reported, and many details including its projected size, cost and potential uses, remain secret. However, military experts say such a facility would be a valuable asset on the island, which is increasingly seen by defense officials as a critical front line in monitoring Chinese submarine and other naval activity in the Indian Ocean. In a time of both misinformation and too much information, quality journalism is more crucial than ever.


Predicting Weekly Fishing Concentration Zones through Deep Learning Integration of Heterogeneous Environmental Spatial Datasets

arXiv.org Artificial Intelligence

The North Indian Ocean, including the Arabian Sea and the Bay of Bengal, represents a vital source of livelihood for coastal communities, yet fishermen often face uncertainty in locating productive fishing grounds. To address this challenge, we present an AI-assisted framework for predicting Potential Fishing Zones (PFZs) using oceanographic parameters such as sea surface temperature and chlorophyll concentration. The approach is designed to enhance the accuracy of PFZ identification and provide region-specific insights for sustainable fishing practices. Preliminary results indicate that the framework can support fishermen by reducing search time, lowering fuel consumption, and promoting efficient resource utilization.

Is a robot programmed to prank you annoying? Yes

New Scientist

Is a robot programmed to prank you annoying? Feedback discovers a robot that can mimic Turkish ice cream vendors, who are known for playing tricks on their customers. Researchers concluded that customers, perhaps predictably, don't trust it Feedback is a grumpy sort, so we run a mile when faced with any kind of enforced fun. It is possible, therefore, that we would struggle to buy an ice cream in Turkey, because doing so requires enjoying, or at least tolerating, an extended prank. Turkish ice cream vendors are prone to playing tricks on their customers, like handing them a cone full of ice cream only to whisk it out of their grasp using sleight of hand.

AFP developing AI tool to decode gen Z slang amid warning about 'crimefluencers' hunting girls

The Guardian

Federal police say they have identified 59 alleged offenders as being in these online networks and have made an unspecified number of arrests. Federal police say they have identified 59 alleged offenders as being in these online networks and have made an unspecified number of arrests. Australian federal police will develop an AI tool to decode gen Z and Alpha slang and emojis in an effort to crackdown on sadistic online exploitation and "crimefluencers". The AFP commissioner, Krissy Barrett, used a speech at the National Press Club on Wednesday to warn of the rise of online crime networks of young boys and men who are targeting vulnerable teen and preteen girls. The newly appointed chief outlined how the perpetrators, who are overwhelmingly from English-speaking backgrounds, were grooming victims and then forcing them to "perform serious acts of violence on themselves, their siblings, others or their pets".


DiNo and RanBu: Lightweight Predictions from Shallow Random Forests

arXiv.org Machine Learning

Random Forest ensembles are a strong baseline for tabular prediction tasks, but their reliance on hundreds of deep trees often results in high inference latency and memory demands, limiting deployment in latency-sensitive or resource-constrained environments. We introduce DiNo (Distance with Nodes) and RanBu (Random Bushes), two shallow-forest methods that convert a small set of depth-limited trees into efficient, distance-weighted predictors. DiNo measures cophenetic distances via the most recent common ancestor of observation pairs, while RanBu applies kernel smoothing to Breiman's classical proximity measure. Both approaches operate entirely after forest training: no additional trees are grown, and tuning of the single bandwidth parameter $h$ requires only lightweight matrix-vector operations. Across three synthetic benchmarks and 25 public datasets, RanBu matches or exceeds the accuracy of full-depth random forests-particularly in high-noise settings-while reducing training plus inference time by up to 95\%. DiNo achieves the best bias-variance trade-off in low-noise regimes at a modest computational cost. Both methods extend directly to quantile regression, maintaining accuracy with substantial speed gains. The implementation is available as an open-source R/C++ package at https://github.com/tiagomendonca/dirf. We focus on structured tabular random samples (i.i.d.), leaving extensions to other modalities for future work.


Smuggler jailed for 40 years after shipping ballistic missiles parts from Iran

BBC News

A weapons smuggler, who used a fishing boat to ship ballistic missile parts from Iran to Houthi rebels in Yemen, has been sentenced to 40 years in a US prison. Pakistani national Muhammad Pahlawan was detained during a US military operation in the Arabian Sea in January 2024 - during which two US Navy Seals drowned. Pahlawan's crew would later testify they had been duped into taking part, having believed they were working as fishermen. The Houthis were launching sustained missile and drone attacks on Israel at the time, as well as targeting international commercial shipping in the Red Sea and Gulf of Aden, saying they were acting in support of the Palestinians in Gaza. Iran has consistently denied arming the Houthis.
