Finite-dimensional approximations of push-forwards on locally analytic functionals

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A new paper presents a functional-analytic framework for approximating the push-forward induced by analytic maps using finitely many samples. The study focuses on the push-forward in the space of locally analytic functionals, employing the Fourier-Borel transform to connect it with operators on entire functions of exponential type, leading to finite-dimensional approximations and error bounds based on Hankel moment matrices.
  • This development is significant as it provides explicit sample complexity bounds for approximations from i.i.d. sampled data, enabling the reconstruction of analytic vector fields from discrete trajectory data. The convergence of a data-driven method for recovering vector fields from ordinary differential equations is also established, enhancing the understanding of dynamic systems.
  • The research aligns with ongoing advancements in the field of artificial intelligence, particularly in the context of improving computational efficiency in various models. The introduction of frameworks that enhance the performance of analytic methods reflects a broader trend of integrating mathematical rigor with practical applications in AI, potentially influencing future developments in machine learning and data analysis.

Convergence of Stochastic Gradient Langevin Dynamics in the Lazy Training Regime
NeutralArtificial Intelligence
A recent study published on arXiv presents a non-asymptotic convergence analysis of stochastic gradient Langevin dynamics (SGLD) in the lazy training regime, demonstrating that SGLD achieves exponential convergence to the empirical risk minimizer under certain conditions. The findings are supported by numerical examples in regression settings.
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.
Control Illusion: The Failure of Instruction Hierarchies in Large Language Models
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 enhance the performance of multi-step agents by focusing on critical actions rather than treating all actions equally. This approach addresses the limitations of conventional policy optimization methods, which often overlook the varying importance of different actions in achieving desired outcomes.
