Rethinking Saliency Maps: A Cognitive Human Aligned Taxonomy and Evaluation Framework for Explanations

The paper titled 'Optimal Self-Consistency for Efficient Reasoning with Large Language Models' presents a comprehensive analysis of self-consistency (SC), a technique used to enhance performance in chain-of-thought reasoning with large language models (LLMs). It discusses the challenges of applying SC at scale and introduces Blend-ASC, a new variant aimed at improving sample efficiency. The study empirically validates power law scaling for SC across datasets, providing insights into its scaling behavior and variants.

The article presents a novel approach to deep hashing called Center-Reassigned Hashing (CRH), which enhances traditional methods by dynamically reassigning hash centers from a preset codebook. This end-to-end framework optimizes the hash function while avoiding the inefficiencies of local similarity optimization and the complexities of two-stage methods. By adapting hash centers to data distribution without explicit optimization phases, CRH aims to improve performance and streamline the learning process in semantic hashing.

Deep neural networks have shown remarkable capabilities in image classification but are susceptible to adversarial examples. Traditional adversarial training improves robustness but often overlooks inter-class feature overlap, which contributes to vulnerability. This study introduces a new adversarial training framework that reduces inter-class proximity by projecting out dependencies from both adversarial and clean samples in the feature space. The method enhances feature separability and theoretically lowers the Lipschitz constant of neural networks, improving generalization.

The paper introduces MCAQ-YOLO, a novel morphological complexity-aware quantization framework designed for efficient object detection. Unlike traditional methods that apply uniform bit precision, MCAQ-YOLO utilizes five morphological metrics to assess local visual complexity and adaptively allocate bit precision. This approach enhances quantization sensitivity and includes a curriculum-based training scheme to progressively increase quantization difficulty, leading to improved optimization and convergence in neural networks.

The paper titled 'QA-Noun: Representing Nominal Semantics via Natural Language Question-Answer Pairs' introduces a new framework called QA-Noun, aimed at capturing noun-centered semantic relations. This framework utilizes nine question templates to address both explicit and implicit roles of nouns, producing interpretable question-answer pairs that enhance existing verbal QA-SRL methods. The authors provide a dataset of over 2,000 annotated noun mentions and a trained model that integrates with QA-SRL, achieving significant coverage of noun arguments and revealing additional contextual relatio…

The paper presents CLIM-FS, a novel method for Incomplete Multi-view Unsupervised Feature Selection (IMUFS) aimed at addressing the challenges of mixed-missing data in multi-view settings. Existing methods struggle with scenarios where entire views or partial features are missing. CLIM-FS integrates the imputation of missing views and variables to enhance feature selection effectiveness, while also addressing the lack of theoretical analysis in the interaction between feature selection and data imputation.

The paper examines entropy calibration in language models, focusing on whether their entropy aligns with log loss on human text. Previous studies indicated that as text generation lengthens, entropy increases while text quality declines, highlighting a fundamental issue in autoregressive models. The authors investigate whether miscalibration can improve with scale and if calibration without tradeoffs is theoretically feasible, analyzing the scaling behavior concerning dataset size and power law exponents.

AtlasMorph introduces a machine learning framework that utilizes convolutional registration neural networks to create conditional deformable templates for brain MRI. These templates are designed to reflect subject-specific attributes such as age and sex, addressing the limitations of existing templates that often do not represent the study population accurately. The approach aims to enhance medical image analysis by producing more representative anatomical segmentation maps when segmentations are available.
