SGEM: Test-Time Adaptation for Automatic Speech Recognition via Sequential-Level Generalized Entropy Minimization

1 code implementation3 Jun 2023 Changhun Kim, Joonhyung Park, Hajin Shim, Eunho Yang

Automatic speech recognition (ASR) models are frequently exposed to data distribution shifts in many real-world scenarios, leading to erroneous predictions.

Fighting Fire with Fire: Contrastive Debiasing without Bias-free Data via Generative Bias-transformation

no code implementations2 Dec 2021 Yeonsung Jung, Hajin Shim, June Yong Yang, Eunho Yang

Deep neural networks (DNNs), despite their impressive ability to generalize over-capacity networks, often rely heavily on malignant bias as shortcuts instead of task-related information for discriminative tasks.

Graph Transplant: Node Saliency-Guided Graph Mixup with Local Structure Preservation

no code implementations10 Nov 2021 Joonhyung Park, Hajin Shim, Eunho Yang

Graph-structured datasets usually have irregular graph sizes and connectivities, rendering the use of recent data augmentation techniques, such as Mixup, difficult.

Mutually-Constrained Monotonic Multihead Attention for Online ASR

no code implementations26 Mar 2021 Jaeyun Song, Hajin Shim, Eunho Yang

Despite the feature of real-time decoding, Monotonic Multihead Attention (MMA) shows comparable performance to the state-of-the-art offline methods in machine translation and automatic speech recognition (ASR) tasks.

Joint Active Feature Acquisition and Classification with Variable-Size Set Encoding

no code implementations NeurIPS 2018 Hajin Shim, Sung Ju Hwang, Eunho Yang

We consider the problem of active feature acquisition where the goal is to sequentially select the subset of features in order to achieve the maximum prediction performance in the most cost-effective way at test time.
