Charting the past year of Russian drone and missile attacks on Ukraine
How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? On Sunday, Russia launched its largest drone and missile attack since the war began, firing a total of 823 projectiles into Ukraine. The attack killed at least four people, wounded 44, and caused damage to a key building in Kyiv's government district, making it the first on the site since the full-fledged war began in February 2022.
Russia-Ukraine war: List of key events, day 1,224
A Ukrainian drone attack on an industrial plant in Izhevsk, in central Russia, killed three people and injured 35 others, regional Governor Alexander Brechalov said in a post on Telegram. The drone struck the Kupol Electromechanical Plant, which produces air defence systems and drones for the Russian military, an unnamed official with Ukraine's Security Service, the SBU, told the Associated Press news agency. A Russian attack on a vehicle evacuating civilians from Pokrovsk, in Ukraine's Donetsk region, killed one person and injured a policeman, police said. The Ministry of Defence in Moscow said that 60 Ukrainian drones were downed overnight over several regions, including 17 over Russian-occupied Crimea, 16 over Russia's Rostov region and four over Russia's Saratov region. Ukraine's Air Force said on Tuesday that Russia launched 52 Shahed and decoy drones at the country overnight.
Ukraine drone attack on central Russia kills three, wounds 35
A Ukrainian drone attack at an industrial plant in central Russia has killed three people and injured 35 others, a Russian regional governor has said. Alexander Brechalov, head of the Udmurt Republic, said in a post on Telegram on Tuesday that the attack took place at a factory in Izhevsk city. Ten of the wounded were in a serious condition, he noted. There was no immediate official comment from Kyiv. But a Ukrainian security official confirmed the attack, telling the news agency Reuters that the Kupol plant had been hit, with a fire breaking out as a result.
SHIELD: LLM-Driven Schema Induction for Predictive Analytics in EV Battery Supply Chain Disruptions
Cheng, Zhi-Qi, Dong, Yifei, Shi, Aike, Liu, Wei, Hu, Yuzhi, O'Connor, Jason, Hauptmann, Alexander, Whitefoot, Kate
The electric vehicle (EV) battery supply chain's vulnerability to disruptions necessitates advanced predictive analytics. We present SHIELD (Schema-based Hierarchical Induction for EV supply chain Disruption), a system integrating Large Language Models (LLMs) with domain expertise for EV battery supply chain risk assessment. SHIELD combines: (1) LLM-driven schema learning to construct a comprehensive knowledge library, (2) a disruption analysis system utilizing fine-tuned language models for event extraction, multi-dimensional similarity matching for schema matching, and Graph Convolutional Networks (GCNs) with logical constraints for prediction, and (3) an interactive interface for visualizing results and incorporating expert feedback to enhance decision-making. Evaluated on 12,070 paragraphs from 365 sources (2022-2023), SHIELD outperforms baseline GCNs and LLM+prompt methods (e.g., GPT-4o) in disruption prediction. These results demonstrate SHIELD's effectiveness in combining LLM capabilities with domain expertise for enhanced supply chain risk assessment.
Detecting value-expressive text posts in Russian social media
Milkova, Maria, Rudnev, Maksim, Okolskaya, Lidia
Basic values are concepts or beliefs which pertain to desirable end-states and transcend specific situations. Studying personal values in social media can illuminate how and why societal values evolve especially when the stimuli-based methods, such as surveys, are inefficient, for instance, in hard-to-reach populations. On the other hand, user-generated content is driven by the massive use of stereotyped, culturally defined speech constructions rather than authentic expressions of personal values. We aimed to find a model that can accurately detect value-expressive posts in Russian social media VKontakte. A training dataset of 5,035 posts was annotated by three experts, 304 crowd-workers and ChatGPT. Crowd-workers and experts showed only moderate agreement in categorizing posts. ChatGPT was more consistent but struggled with spam detection. We applied an ensemble of human- and AI-assisted annotation involving active learning approach, subsequently trained several LLMs and selected a model based on embeddings from pre-trained fine-tuned rubert-tiny2, and reached a high quality of value detection with F1 = 0.75 (F1-macro = 0.80). This model provides a crucial step to a study of values within and between Russian social media users.
Mobile Robot Control and Autonomy Through Collaborative Simulation Twin
Tahir, Nazish, Parasuraman, Ramviyas
When a mobile robot lacks high onboard computing or networking capabilities, it can rely on remote computing architecture for its control and autonomy. This paper introduces a novel collaborative Simulation Twin (ST) strategy for control and autonomy on resource-constrained robots. The practical implementation of such a strategy entails a mobile robot system divided into a cyber (simulated) and physical (real) space separated over a communication channel where the physical robot resides on the site of operation guided by a simulated autonomous agent from a remote location maintained over a network. Building on top of the digital twin concept, our collaborative twin is capable of autonomous navigation through an advanced SLAM-based path planning algorithm, while the physical robot is capable of tracking the Simulated twin's velocity and communicating feedback generated through interaction with its environment. We proposed a prioritized path planning application to the test in a collaborative teleoperation system of a physical robot guided by ST's autonomous navigation. We examine the performance of a physical robot led by autonomous navigation from the Collaborative Twin and assisted by a predicted force received from the physical robot. The experimental findings indicate the practicality of the proposed simulation-physical twinning approach and provide computational and network performance improvements compared to typical remote computing (or offloading), and digital twin approaches.
Type-aware Convolutional Neural Networks for Slot Filling
Adel, Heike, Schuetze, Hinrich
The slot filling task aims at extracting answers for queries about entities from text, such as "Who founded Apple". In this paper, we focus on the relation classification component of a slot filling system. We propose type-aware convolutional neural networks to benefit from the mutual dependencies between entity and relation classification. In particular, we explore different ways of integrating the named entity types of the relation arguments into a neural network for relation classification, including a joint training and a structured prediction approach. To the best of our knowledge, this is the first study on type-aware neural networks for slot filling. The type-aware models lead to the best results of our slot filling pipeline. Joint training performs comparable to structured prediction. To understand the impact of the different components of the slot filling pipeline, we perform a recall analysis, a manual error analysis and several ablation studies. Such analyses are of particular importance to other slot filling researchers since the official slot filling evaluations only assess pipeline outputs. The analyses show that especially coreference resolution and our convolutional neural networks have a large positive impact on the final performance of the slot filling pipeline. The presented models, the source code of our system as well as our coreference resource is publicly available.
