In the Soccer Simulation 2D environment, accurate observation is crucial for effective decision-making. However, challenges such as partial observation and noisy data can hinder performance. To address these issues, we propose a denoising algorithm that leverages predictive modeling and intersection analysis to enhance the accuracy of observations. Our approach aims to mitigate the impact of noise and partial data, leading to improved gameplay performance. This paper presents the framework, implementation, and preliminary results of our algorithm, demonstrating its potential in refining observations in Soccer Simulation 2D. Cyrus 2D Team is using a combination of Helios, Gliders, and Cyrus base codes[1,2,3].


Towards Complex Ontology Alignment using Large Language Models

Ontology alignment, a critical process in the Semantic Web for detecting relationships between different ontologies, has traditionally focused on identifying so-called "simple" 1-to-1 relationships through class labels and properties comparison. The more practically useful exploration of more complex alignments remains a hard problem to automate, and as such is largely underexplored, i.e. in application practice it is usually done manually by ontology and domain experts. Recently, the surge in Natural Language Processing (NLP) capabilities, driven by advancements in Large Language Models (LLMs), presents new opportunities for enhancing ontology engineering practices, including ontology alignment tasks. This paper investigates the application of LLM technologies to tackle the complex ontology alignment challenge. Leveraging a prompt-based approach and integrating rich ontology content - so-called modules - our work constitutes a significant advance towards automating the complex alignment task.


Iran prosecutor general signals 'morality police' suspended

Al Jazeera

Tehran, Iran – Iran has suspended its morality police as the country continues to deal with two months of protests, the Iranian prosecutor general has suggested. The protests erupted shortly after the death of Mahsa Amini, a 22-year-old woman who was arrested by a unit of the morality police in Tehran for allegedly not adhering to the country's mandatory dress code for women. Speaking on Saturday at an event aimed at "outlining the hybrid war during recent riots", which is how Iranian officials describe alleged foreign influence in the unrest, prosecutor general Mohammad Jafar Montazeri was quoted as saying by local media the morality police operations are over. The morality police "has no connection with the judiciary and was shut down by the same place that it had been launched from in the past", he said, reportedly answering a question on why the morality police has been shut down. There were no other confirmations that work of the patrolling units – officially tasked with ensuring "moral security" in the society – has been terminated.


White House says Iran helping Russia 'on the ground' in Crimea

Al Jazeera

The White House has accused Iran of being "directly engaged on the ground" in Russian-occupied Crimea, helping to train the country's forces on Iranian-made drones that have been used in attacks in Ukraine. US National Security Council spokesman John Kirby said on Thursday that a "relatively small number" of Iranian personnel are operating in the Ukrainian region that was annexed by Russia in 2014. "Tehran is now directly engaged on the ground and through the provision of weapons that are impacting civilians and civilian infrastructure in Ukraine," Kirby said. "The United States is going to pursue all means to expose, deter and confront Iran's provision of these munitions against the Ukrainian people." Tehran has denied supplying Moscow with drones or helping launch them.


Nine dead in Iranian attacks on Kurdish rebels in northern Iraq

Al Jazeera

Iran has attacked an Iranian-Kurdish opposition group in the Kurdish region of northern Iraq, killing nine people and injuring several others, Kurdish officials said. The missile and drone attacks on Wednesday focused on bases in Koya, some 60km (35 miles) east of Erbil, said Soran Nuri – a member of the Democratic Party of Iranian Kurdistan. The group, known by the acronym KDPI, is a left-wing armed opposition force that is banned in Iran. Iran's state-run IRNA news agency and broadcaster said Iran's Revolutionary Guard Corps ground forces targeted some bases of a separatist group in the north of Iraq with "precision missiles" and a "suicide drone". "This operation will continue with our full determination until the threat is effectively repelled, terrorist groups' bases are dismantled, and the authorities of the Kurdish region assume their obligations and responsibilities," the IRGC said in a statement read on state television. Nine people were killed and 24 wounded, according to Kurdistan Regional Government's health minister, Saman Barazanchi.


IBM's AutoAI Has The Smarts To Make Data Scientists A Lot More Productive – But What's Scary Is That It's Getting A Whole Lot Smarter

#artificialintelligence

I recently had the opportunity to discuss current IBM artificial intelligence developments with Dr. Lisa Amini, an IBM Distinguished Engineer and the Director of IBM Research Cambridge, home to the MIT-IBM Watson AI Lab. Dr. Amini was previously Director of Knowledge & Reasoning Research in the Cognitive Computing group at IBM's TJ Watson Research Center in New York. Dr. Amini earned her Ph.D. degree in Computer Science from Columbia University. Dr. Amini and her team are part of IBM Research tasked with creating the next generation of Automated AI and data science. I was interested in automation's impact on the lifecycles of artificial intelligence and machine learning and centered our discussion around next-generation capabilities for AutoAI. AutoAI automates the highly complex process of finding and optimizing the best ML model, features, and model hyperparameters for your data.


Distributed Learning of Generalized Linear Causal Networks

Ye, Qiaoling, Amini, Arash A., Zhou, Qing

We consider the task of learning causal structures from data stored on multiple machines, and propose a novel structure learning method called distributed annealing on regularized likelihood score (DARLS) to solve this problem. We model causal structures by a directed acyclic graph that is parameterized with generalized linear models, so that our method is applicable to various types of data. To obtain a high-scoring causal graph, DARLS simulates an annealing process to search over the space of topological sorts, where the optimal graphical structure compatible with a sort is found by a distributed optimization method. This distributed optimization relies on multiple rounds of communication between local and central machines to estimate the optimal structure. We establish its convergence to a global optimizer of the overall score that is computed on all data across local machines. To the best of our knowledge, DARLS is the first distributed method for learning causal graphs with such theoretical guarantees. Through extensive simulation studies, DARLS has shown competing performance against existing methods on distributed data, and achieved comparable structure learning accuracy and test-data likelihood with competing methods applied to pooled data across all local machines. In a real-world application for modeling protein-DNA binding networks with distributed ChIP-Sequencing data, DARLS also exhibits higher predictive power than other methods, demonstrating a great advantage in estimating causal networks from distributed data.


Researchers' algorithm designs soft robots that sense

Robohub

There are some tasks that traditional robots -- the rigid and metallic kind -- simply aren't cut out for. Soft-bodied robots, on the other hand, may be able to interact with people more safely or slip into tight spaces with ease. But for robots to reliably complete their programmed duties, they need to know the whereabouts of all their body parts. MIT researchers have developed an algorithm to help engineers design soft robots that collect more useful information about their surroundings. The deep-learning algorithm suggests an optimized placement of sensors within the robot's body, allowing it to better interact with its environment and complete assigned tasks. The advance is a step toward the automation of robot design.


Artificial Intelligence Is Now Smart Enough to Know When It Can't Be Trusted

How might The Terminator have played out if Skynet had decided it probably wasn't responsible enough to hold the keys to the entire US nuclear arsenal? As it turns out, scientists may just have saved us from such a future AI-led apocalypse, by creating neural networks that know when they're untrustworthy. These deep learning neural networks are designed to mimic the human brain by weighing up a multitude of factors in balance with each other, spotting patterns in masses of data that humans don't have the capacity to analyse. While Skynet might still be some way off, AI is already making decisions in fields that affect human lives like autonomous driving and medical diagnosis, and that means it's vital that they're as accurate as possible. To help towards this goal, this newly created neural network system can generate its confidence level as well as its predictions.
