Paper abstract: In this paper, the researcher introduces "KiloGram", a user A resource library for studying abstract visual reasoning in humans and machines. KiloGram greatly improves existing resources in two ways. First, the researchers curated and digitized 1,016 shapes, creating a collection that was two orders of magnitude larger than those used in existing work. This collection greatly increases coverage of the entire range of naming variation, providing a more comprehensive perspective on human naming behavior. Second, the collection treats each tangram not as a single overall shape, but as a vector shape made up of the original puzzle pieces. This decomposition enables reasoning about whole shapes and their parts. The researchers used this new collection of digital jigsaw puzzle graphics to collect a large amount of textual description data, reflecting the high diversity of naming behavior.

We leveraged crowdsourcing to extend the annotation process, collecting multiple annotations for each shape to represent the distribution of annotations it elicited rather than a single sample. A total of 13,404 annotations were collected, each describing a complete object and its divided parts.

KiloGram’s potential is extensive. We used this resource to evaluate the abstract visual reasoning capabilities of recent multimodal models and observed that pre-trained weights exhibited limited abstract reasoning capabilities that improved greatly with fine-tuning. They also observed that explicit descriptions facilitate abstract reasoning by both humans and models, especially when jointly encoding language and visual input.

Figure 1 is an example of two tangrams, each with two different annotations. Each annotation includes a description of the entire shape (in bold), a segmentation of the parts (in color), and a name for each part (connected to each part). The upper example shows low variability for near perfect agreement, while the lower example shows high variability for language and segmentation divergence.

Paper: Interpreting Language Models with Contrastive Explanations

• Author: Kayo Yin, Graham Neubig

Paper abstract: Model interpretability methods are often used to explain the decisions of NLP models on tasks such as text classification. , the output space of these tasks is relatively small. However, when applied to language generation, the output space often consists of tens of thousands of tokens, and these methods cannot provide informative explanations. Language models must consider various features to predict a token, such as its part of speech, number, tense, or semantics. Because existing explanatory methods combine evidence for all these features into a single explanation, this is less interpretable to human understanding.

To distinguish between different decisions in language modeling, researchers have explored language models that focus on contrastive explanations. They look for input tokens that stand out and explain why the model predicted one token but not another. Research demonstrates that contrastive explanations are much better than non-contrastive explanations at validating major grammatical phenomena, and that they significantly improve contrastive model simulatability for human observers. The researchers also identified groups of contrastive decisions for which the model used similar evidence and were able to describe which input tokens the model used in various language generation decisions.

Paper: Topic-Regularized Authorship Representation Learning

• ## Author: Jitkapat Sawatphol, Nonthakit Chaiwong, Can Udomcharoenchaikit, Sarana Nutanong
• Institution: VISTEC Institute of Science and Technology, Thailand

Abstract ：In this study, the researchers proposed Authorship Representation Regularization, a distillation framework that can improve cross-topic performance and can also handle unseen authors. This approach can be applied to any authorship representation model. Experimental results show that in the cross-topic setting, 4/6 performance is improved. At the same time, researchers' analysis shows that in data sets with a large number of topics, training shards set across topics have topic information leakage problems, thus weakening their ability to evaluate cross-topic attributes.

Paper: Evaluate & Evaluation on the Hub: Better Best Practices for Data and Model Measurements

##Authors: Leandro von Werra, Lewis Tunstall, Abhishek Thakur, Alexandra Sasha Luccioni, etc.
Organization: Hugging Face

Paper abstract:Evaluation is a key part of machine learning (ML), and this study introduces Evaluate and Evaluation on Hub - a set of tools that help evaluate Tools for models and datasets in ML. Evaluate is a library for comparing different models and datasets, supporting various metrics. The Evaluate library is designed to support reproducibility of evaluations, document the evaluation process, and expand the scope of evaluations to cover more aspects of model performance. It includes more than 50 efficient specification implementations for a variety of domains and scenarios, interactive documentation, and the ability to easily share implementation and evaluation results.
