RCTDistill: Cross-Modal Knowledge Distillation Framework for Radar-Camera 3D Object Detection with Temporal Fusion
Radar-camera fusion methods have emerged as a cost-effective approach for 3D object detection but still lag behind LiDAR-based methods in performance. Recent works have focused on employing temporal fusion and Knowledge Distillation (KD) strategies to overcome these limitations. However, existing approaches have not sufficiently accounted for uncertainties arising from object motion or sensor-specific errors inherent in radar and camera modalities. In this work, we propose RCTDistill, a novel c…

Abstract: Effectively capturing long-range interactions remains a fundamental yet unresolved challenge in graph neural network (GNN) research, critical for applications across diverse fields of science. To systematically address this, we introduce ECHO (Evaluating Communication over long HOps), a novel benchmark specifically designed to rigorously assess the capabilities of GNNs in handling very long-range graph propagation. ECHO includes three synthetic graph tasks, namely single-source shortest paths, node eccentricity, and graph diameter, each constructed over diverse and structurally challenging topologies intentionally designed to introduce significant information bottlenecks. ECHO also includes two real-world datasets, ECHO-Charge and ECHO-Energy, which define chemically grounded benchmarks for predicting atomic partial charges and molecular total energies, respectively, with reference computations obtained at the density functional theory (DFT) level. Both tasks inherently depend on capturing complex long-range molecular interactions. Our extensive benchmarking of popular GNN architectures reveals clear performance gaps, emphasizing the difficulty of true long-range propagation and highlighting design choices capable of overcoming inherent limitations. ECHO thereby sets a new standard for evaluating long-range information propagation, also providing a compelling example for its need in AI for science.

Mean-tail Gini framework for optimal portfolio selection
The limitations of the traditional mean-variance (MV) efficient frontier, as introduced by Markowitz (1952), have been extensively documented in the literature. Specifically, the assumptions of normally distributed returns or quadratic investor preferences are often unrealistic in practice. Moreover, variance is not always an appropriate risk measure, particularly for heavy-tailed and highly volatile distributions, such as those observed in insurance claims and cryptocurrency markets, which may…

I feel as though I should illustrate the difference that this one single constraint can make by two examples.
The rules of Simon Says are maximally authoritarian. You must perform any action ordered, with the only restriction that the authority must say "Simon says" first. Were you forced to stay in this system, it would be the most despotic autocracy possible. But it's not. It's a silly game because you can leave at any time.
Let's flip this and imagine a room. During a specific period of time you will have absolute control over everything in this room. In this room you have total freedom. This is not even the limited freedom, the coordinated freedom, the compromising freedom of civil society. You could, without consequence, perform any action you wish in this room. You could say anything, destroy or steal any object, order any individual to perform any action, kill any person in the room with you and take anything they own. This is the sovereign freedom, the absolute freedom, of dictators and kings. The only restriction is that you are not allowed to leave the room while you have this freedom. In fact, you really only have this level of freedom because the room is actually empty other than for you. I am, of course, talking about a form of torture still common in the US: solitary confinement.

The Supreme Courtsaid on Friday that it will take up its latest gun rights case
and consider striking down a strict regulation on where people can carry firearms in Hawaii.
Trump’s administration had urged the justices to take the case.
The court will consider Hawaii’s law that bans guns on private property,
including businesses like stores and hotels,
unless the owner has specifically allowed them verbally or with a sign.

Supreme Court will consider overturning strict Hawaii gun law
The Supreme Court says it'll take up its latest gun rights case and consider striking down strict regulations on where people can carry firearms in Hawaii. President Donald Trump’s Republican administration had urged the justices to take the case, arguing the law violates the court’s 2022 ruling that found people have a right to carry firearms in public under the Second Amendment. The Hawaii law bans guns on private property unless the owner has specifically allowed them. The law also prohi…

Query-Specific GNN: A Comprehensive Graph Representation Learning Method for Retrieval Augmented Generation
Retrieval-augmented generation (RAG) has demonstrated its ability to enhance Large Language Models (LLMs) by integrating external knowledge sources. However, multi-hop questions, which require the identification of multiple knowledge targets to form a synthesized answer, raise new challenges for RAG systems. Under the multi-hop settings, existing methods often struggle to fully understand the questions with complex semantic structures and are susceptible to irrelevant noise during the retrieval…
