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 importance of calibration in language models and its impact on their effectiveness in addressing urgent issues such as climate change.
The paper presents a new technique called Next Distribution Prediction (NDP) that addresses the limitations of the existing Next-Token Prediction (NTP) paradigm in large language models (LLMs). By using $n$-gram distributions instead of one-hot targets, NDP shows significant improvements in translation, general tasks, language transfer, and medical domain adaptation. This highlights the potential for NDP to have a lasting impact on academic research in improving NTP and enhancing learning in 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 MOE architecture using the toolkit. The availability of a public repository makes this technique accessible for academic research, potentially leading to lasting impact in the field.
This paper explores the use of different methods of neuron ablation in transformer-based models to better understand how attention mechanisms represent concepts. Through experimental analysis, the authors find that peak ablation, a novel approach, offers the lowest degradation of model performance compared to other methods. This has the potential to greatly impact academic research in the interpretation of transformer-based models and their attention mechanisms.
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 delivery datasets. This has the potential to greatly benefit academic research in the field of urban delivery demand management.
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 is a hybrid behavioral testing framework that uses large language models to generate a wide range of test types for a comprehensive evaluation of NLP models. By automating the process of creating test types, it reduces the need for human labor and allows for a more thorough and interpretable assessment of NLP models. This has the potential to greatly impact academic research in NLP by providing a more efficient and effective way to evaluate model performance.
The paper presents a new fine-tuning technique, MoRe, which uses the Monarch matrix class to efficiently search for optimal adapter architectures. This approach has been shown to be more expressive and parameter-efficient than current state-of-the-art techniques, potentially leading to lasting impacts in academic research by improving performance and reducing the number of parameters needed for fine-tuning large pretrained models.
This paper presents a novel approach to electricity demand forecasting using graph-based models such as Graph Convolutional Networks and Graph SAGE. By incorporating interconnectedness and information sharing among nodes, the proposed methodology effectively captures the complexities of decentralized networks. The paper also introduces methods for inferring graphs tailored to consumption forecasting and provides a framework for evaluating the models in terms of performance and explainability. This research has the potential to significantly impact the field of electricity demand forecasting in academic research.
