BTS: Back TranScription for Speech-to-Text Post-Processor using Text-to-Speech-to-Text

no code implementations ACL (WAT) 2021 Chanjun Park, Jaehyung Seo, Seolhwa Lee, Chanhee Lee, Hyeonseok Moon, Sugyeong Eo, Heuiseok Lim

Automatic speech recognition (ASR) is arguably the most critical component of such systems, as errors in speech recognition propagate to the downstream components and drastically degrade the user experience.

Towards Reliable and Fluent Large Language Models: Incorporating Feedback Learning Loops in QA Systems

no code implementations8 Sep 2023 Dongyub Lee, Taesun Whang, Chanhee Lee, Heuiseok Lim

First, we build a dataset to train a critic model capable of evaluating the citation, correctness, and fluency of responses generated by LLMs in QA systems.

A Deep Dive into NFT Whales: A Longitudinal Study of the NFT Trading Ecosystem

no code implementations2 Feb 2023 Na Hyeon Park, Hanna Kim, Chanhee Lee, Changhoon Yoon, Seunghyeon Lee, Youngjin Jin, Seungwon Shin

NFT (Non-fungible Token) has drastically increased in its size, accounting for over \$16. 9B of total market capitalization.

Analysis of Utterance Embeddings and Clustering Methods Related to Intent Induction for Task-Oriented Dialogue

1 code implementation5 Dec 2022 Jeiyoon Park, Yoonna Jang, Chanhee Lee, Heuiseok Lim

The focus of this work is to investigate unsupervised approaches to overcome quintessential challenges in designing task-oriented dialog schema: assigning intent labels to each dialog turn (intent clustering) and generating a set of intents based on the intent clustering methods (intent induction).

Language Chameleon: Transformation analysis between languages using Cross-lingual Post-training based on Pre-trained language models

no code implementations14 Sep 2022 Suhyune Son, Chanjun Park, Jungseob Lee, Midan Shim, Chanhee Lee, Yoonna Jang, Jaehyung Seo, Heuiseok Lim

This can be attributed to the fact that the amount of available training data in each language follows the power-law distribution, and most of the languages belong to the long tail of the distribution.

Multimodal Frame-Scoring Transformer for Video Summarization

no code implementations5 Jul 2022 Jeiyoon Park, Kiho Kwoun, Chanhee Lee, Heuiseok Lim

Second, existing datasets for generic video summarization are relatively insufficient to train a caption generator used for extracting text information from a video and to train the multimodal feature extractors.

Variational Reward Estimator Bottleneck: Learning Robust Reward Estimator for Multi-Domain Task-Oriented Dialog

no code implementations31 May 2020 Jeiyoon Park, Chanhee Lee, Kuekyeng Kim, Heuiseok Lim

Despite its notable success in adversarial learning approaches to multi-domain task-oriented dialog system, training the dialog policy via adversarial inverse reinforcement learning often fails to balance the performance of the policy generator and reward estimator.

Rich Character-Level Information for Korean Morphological Analysis and Part-of-Speech Tagging

no code implementations COLING 2018 Andrew Matteson, Chanhee Lee, Young-Bum Kim, Heuiseok Lim

Due to the fact that Korean is a highly agglutinative, character-rich language, previous work on Korean morphological analysis typically employs the use of sub-character features known as graphemes or otherwise utilizes comprehensive prior linguistic knowledge (i. e., a dictionary of known morphological transformation forms, or actions).
