TMLR, 2024
Yuhta Takida, Yukara Ikemiya, Takashi Shibuya, Kazuki Shimada, Woosung Choi, Chieh-Hsin Lai, Naoki Murata, Toshimitsu Uesaka, Kengo Uchida, Wei-Hsiang Liao, Yuki Mitsufuji*

Vector quantization (VQ) is a technique to deterministically learn features with discrete codebook representations. It is commonly performed with a variational autoencoding model, VQ-VAE, which can be further extended to hierarchical structures for making high-fidelity recon…

Zero- and Few-shot Sound Event Localization and Detection

ICASSP, 2024
Kazuki Shimada, Kengo Uchida, Yuichiro Koyama*, Takashi Shibuya, Shusuke Takahashi*, Yuki Mitsufuji*, Tatsuya Kawahara*

Sound event localization and detection (SELD) systems estimate direction-of-arrival (DOA) and temporal activation for sets of target classes. Neural network (NN)-based SELD systems have performed well in various sets of target classes, but they only output the DOA and tempor…
