The paper presents the Greek podcast corpus, a large dataset of Modern Greek speech data collected from podcasts and used to improve speech recognition models. The study demonstrates the potential of leveraging weak supervision to enhance the performance of speech technologies in under-resourced languages. This approach could have a lasting impact on academic research by providing a cost-effective strategy for developing speech technologies in languages with limited digital representation.
This paper explores the potential for language models to improve their planning abilities by constructing a cognitive map of a given environment, inspired by human cognitive processes. The experiments demonstrate that this approach significantly enhances both optimal and reachable planning generation in the Gridworld task, showcasing characteristics similar to human cognition. This has the potential to advance the development of more advanced and robust systems that better resemble human cognition in language models.
The paper presents a new technique called Gradient-Mask Tuning (GMT) that selectively updates parameters during training based on their gradient information. This method has been shown to outperform traditional fine-tuning methods and elevate the upper limits of LLM performance in various tasks. It also exhibits insensitivity to mask ratio and has comparable computational efficiency to vanilla SFT. This has the potential to greatly impact academic research in the field of large language models.
This paper evaluates the potential of Large Language Models (LLMs) such as ChatGPT and Bard to provide accurate and relevant responses to historical questions in French. The study reveals several shortcomings in the LLMs' ability to generate reliable and consistent responses, highlighting the need for further development and improvement in this area. These findings have the potential to impact and improve the use of LLMs in academic research on historical topics.
The paper presents a new hierarchical transformer model, called Fieldy, for analyzing time-series tabular data. This model allows for fine-grained attention at both the row and column levels, improving performance without increasing model size. This technique has the potential to greatly impact academic research in the analysis of tabular time-series data, as it allows for more detailed and accurate modeling of patterns at the field-level.
This paper presents a novel method for extracting dialogue policies from conversational data using Large Language Models (LLMs) and a graph-based approach. By converting conversations into a unified intermediate representation, the proposed technique offers a more efficient and controllable way to generate dialogue flows. This has the potential to greatly benefit the development and maintenance of task-oriented dialogue systems, providing a productivity tool for conversation designers.
This paper explores the potential for faithfulness metrics to improve the accuracy of citations in large language models. By proposing a comparative evaluation framework, the authors demonstrate the complexity of assessing fine-grained citation support and provide practical recommendations for developing more effective metrics. This has the potential to greatly impact academic research by improving the reliability and verifiability of information generated by LLMs.
The paper presents a Hybrid Alignment Training (Hbat) approach for large language models (LLMs) that alternates between instruction-following alignment and human-preference alignment. This approach aims to improve collaboration between the two alignment tasks and has shown significant performance gains in summarization and dialogue tasks. This technique has the potential to create a lasting impact in academic research by addressing the inherent conflict between these two alignment objectives and improving the overall performance of LLMs.
Generative Topological Networks (GTNs) are a new class of generative models that are fast to train and require only a single forward pass to generate samples. This is achieved through a simple supervised learning approach grounded in topology theory. The potential for GTNs to improve performance and offer insights into training generative models could have a lasting impact in academic research.
The paper "LongRAG: Enhancing Retrieval-Augmented Generation with Long-context LLMs" proposes a new framework that combines a "long retriever" and a "long reader" to improve performance in retrieval-augmented generation tasks. By increasing the unit size and reducing the total number of units, the burden on the retriever is lowered, resulting in significantly improved retrieval scores. The use of long-context LLMs also leads to impressive results in zero-shot answer extraction. This paper offers valuable insights for future research in combining RAG with long-context LLMs.
