This paper explores the modularity and task specialization of neurons in transformer models, specifically in vision and language models. Through selective pruning and MoEfication clustering techniques, the authors identify task-specific neuron clusters with varying degrees of overlap between related tasks. These findings suggest an inherent structure in transformer models that can be refined through training, providing potential avenues for improving model interpretability and efficiency.
This paper evaluates the performance and self-evaluation capabilities of three language models in classification tasks related to environmental and climate change. While BERT-based models generally outperform the generative models, the latter still show promise. The study also highlights the strengths and limitations of these models in addressing urgent ecological issues, contributing to the ongoing discussion on their utility in academic research.
The paper presents a new technique called Next Distribution Prediction (NDP) that addresses the limitations of the existing Next-Token Prediction (NTP) paradigm used in large language models (LLMs). By using $n$-gram distributions instead of one-hot targets, NDP shows significant improvements in various tasks such as translation, general tasks, and medical domain adaptation. This highlights the potential for NDP to have a lasting impact on academic research in improving NTP and LLMs.
This paper introduces a toolkit for creating low-cost Mixture-of-Domain-Experts (MOE) from trained models or adapters. The authors conduct thorough tests and provide guidance on how to define the architecture of the resulting MOE using the toolkit. The availability of a public repository makes this technique easily accessible for academic research, potentially leading to a lasting impact in the field.
This paper explores the use of different methods of neuron ablation in transformer-based models to better understand their attention mechanisms. Through experimental analysis, the authors find that peak ablation offers the lowest degradation of model performance compared to other methods. This has the potential to greatly impact academic research by providing a more effective way to interpret and analyze transformer-based models.
This paper presents a novel approach for predicting city-wide delivery demand using a combination of graph-based learning and large language models. By incorporating geospatial knowledge and utilizing an inductive training scheme, the proposed model outperforms existing methods on real-world datasets from multiple cities. This has the potential to greatly benefit the field of urban delivery demand management and advance data-driven predictive methods in academic research.
This paper explores the geometry of self-attention networks without normalization, using tools from algebraic geometry. The authors provide a theoretical analysis of the identifiability and dimension of these networks, and also extend their results to normalized self-attention networks. This research has the potential to significantly impact the understanding and application of self-attention techniques in academic research.
SYNTHEVAL offers a hybrid behavioral testing framework that utilizes large language models to generate a wide range of test types for a comprehensive evaluation of NLP models. This approach addresses the limitations of traditional benchmarking and offers a more dynamic and interpretable assessment of NLP models. By automating the process of generating test types, SYNTHEVAL has the potential to significantly reduce the human labor and cost involved in NLP research, making it a valuable tool for future academic research.
The paper presents a new technique, Monarch Rectangular Fine-tuning (MoRe), for parameter-efficient fine-tuning of large pretrained models. This approach uses the Monarch matrix class to search for optimal adapter architectures, making it more expressive than existing techniques. Empirical results show that MoRe is more efficient and effective than state-of-the-art methods, with potential to significantly impact academic research in this area.
This paper explores the potential of using graph neural networks for accurate electricity demand forecasting. By incorporating the spatial distribution and relational intricacies of a decentralized network structure, these models offer a novel approach beyond traditional methods. The paper presents a range of methods for inferring graphs and evaluates their performance and explainability. The results of experiments on electricity forecasting demonstrate the potential for lasting impact in academic research.
