Learning Single-Image Super-Resolution in the JPEG Compressed Domain

arXiv — cs.CVFriday, December 5, 2025 at 5:00:00 AM
  • A new approach to single-image super-resolution (SISR) has been introduced, focusing on training models directly on JPEG compressed features. This method significantly reduces data loading times and computational overhead by operating on JPEG discrete cosine transform (DCT) coefficients, achieving notable speed improvements in training and inference while maintaining visual quality.
  • This development is crucial as it addresses the persistent bottleneck of data loading in deep learning, allowing for faster training and inference processes. The lightweight pipeline enhances efficiency, making it a valuable contribution to the field of artificial intelligence and image processing.
  • The advancement aligns with ongoing efforts in the AI community to optimize model training and performance, particularly in scenarios where data efficiency is paramount. Similar methodologies are being explored across various domains, including remote sensing and low-light image processing, highlighting a trend towards more efficient and scalable AI solutions.

LongVT: Incentivizing "Thinking with Long Videos" via Native Tool Calling
PositiveArtificial Intelligence
LongVT has been introduced as an innovative framework designed to enhance video reasoning capabilities in large multimodal models (LMMs) by facilitating a process known as 'Thinking with Long Videos.' This approach utilizes a global-to-local reasoning loop, allowing models to focus on specific video clips and retrieve relevant visual evidence, thereby addressing challenges associated with long-form video processing.
LangSAT: A Novel Framework Combining NLP and Reinforcement Learning for SAT Solving
PositiveArtificial Intelligence
A novel framework named LangSAT has been introduced, which integrates reinforcement learning (RL) with natural language processing (NLP) to enhance Boolean satisfiability (SAT) solving. This system allows users to input standard English descriptions, which are then converted into Conjunctive Normal Form (CNF) expressions for solving, thus improving accessibility and efficiency in SAT-solving processes.
Geschlechts\"ubergreifende Maskulina im Sprachgebrauch Eine korpusbasierte Untersuchung zu lexemspezifischen Unterschieden
NeutralArtificial Intelligence
A recent study published on arXiv investigates the use of generic masculines (GM) in contemporary German press texts, analyzing their distribution and linguistic characteristics. The research focuses on lexeme-specific differences among personal nouns, revealing significant variations, particularly between passive role nouns and prestige-related personal nouns, based on a corpus of 6,195 annotated tokens.
Limit cycles for speech
PositiveArtificial Intelligence
Recent research has uncovered a limit cycle organization in the articulatory movements that generate human speech, challenging the conventional view of speech as discrete actions. This study reveals that rhythmicity, often associated with acoustic energy and neuronal excitations, is also present in the motor activities involved in speech production.
Natural Language Actor-Critic: Scalable Off-Policy Learning in Language Space
PositiveArtificial Intelligence
The Natural Language Actor-Critic (NLAC) algorithm has been introduced to enhance the training of large language model (LLM) agents, which interact with environments over extended periods. This method addresses challenges in learning from sparse rewards and aims to stabilize training through a generative LLM critic that evaluates actions in natural language space.

NegativeArtificial Intelligence
Recent research highlights the limitations of hierarchical instruction schemes in large language models (LLMs), revealing that these models struggle with consistent instruction prioritization, even in simple cases. The study introduces a systematic evaluation framework to assess how effectively LLMs enforce these hierarchies, finding that the common separation of system and user prompts fails to create a reliable structure.
CARL: Critical Action Focused Reinforcement Learning for Multi-Step Agent
PositiveArtificial Intelligence
CARL, a new reinforcement learning algorithm, has been introduced to optimize multi-step agents by focusing on critical actions that significantly influence outcomes, rather than treating all actions equally. This approach aims to enhance the efficiency and performance of training and inference processes in complex task environments.
Multi-LLM Collaboration for Medication Recommendation
PositiveArtificial Intelligence
A new approach to medication recommendation utilizing multi-large language model (LLM) collaboration has been proposed, addressing the critical challenge of reliability in AI-driven clinical decision support. This method builds on previous work in LLM Chemistry, focusing on enhancing the stability and credibility of recommendations derived from brief clinical vignettes.
