Bridging Past and Future: Distribution-Aware Alignment for Time Series Forecasting

arXiv:2509.14181v1 Announce Type: cross Abstract: Representation learning techniques like contrastive learning have long been explored in time series forecasting, mirroring their success in computer vision and natural language processing. Yet recent state-of-the-art (SOTA) forecasters seldom adopt these representation approaches because…

ECHO: Frequency-aware Hierarchical Encoding for Variable-length Signals

arXiv:2508.14689v2 Announce Type: replace-cross Abstract: Pre-trained foundation models have demonstrated remarkable success in audio, vision and language, yet their potential for general machine signal modeling with arbitrary sampling rates-covering acoustic, vibration, and other industrial sensor data-remains under-explored. In this work,…

Evaluation Awareness Scales Predictably in Open-Weights Large Language Models

arXiv:2509.13333v1 Announce Type: new Abstract: Large language models (LLMs) can internally distinguish between evaluation and deployment contexts, a behaviour known as emph{evaluation awareness}. This undermines AI safety evaluations, as models may conceal dangerous capabilities during testing. Prior work demonstrated this…

Beyond checkmate: exploring the creative chokepoints in AI text

arXiv:2501.19301v2 Announce Type: replace-cross Abstract: The rapid advancement of Large Language Models (LLMs) has revolutionized text generation but also raised concerns about potential misuse, making detecting LLM-generated text (AI text) increasingly essential. While prior work has focused on identifying AI…

OpenHA: A Series of Open-Source Hierarchical Agentic Models in Minecraft

arXiv:2509.13347v1 Announce Type: new Abstract: The choice of action spaces is a critical yet unresolved challenge in developing capable, end-to-end trainable agents. This paper first presents a large-scale, systematic comparison of prominent abstracted action spaces and tokenizers for Vision-Language-Action (VLA)…

Imagined Autocurricula

arXiv:2509.13341v1 Announce Type: new Abstract: Training agents to act in embodied environments typically requires vast training data or access to accurate simulation, neither of which exists for many cases in the real world. Instead, world models are emerging as an…

Position: AI Safety Must Embrace an Antifragile Perspective

arXiv:2509.13339v1 Announce Type: new Abstract: This position paper contends that modern AI research must adopt an antifragile perspective on safety — one in which the system’s capacity to guarantee long-term AI safety such as handling rare or out-of-distribution (OOD) events…
