Can VLM Pseudo-Labels Train a Time-Series QA Model That Outperforms the VLM?

Takuya Fujimura, Kota Dohi, Natsuo Yamashita +1

Time-series question answering (TSQA) tasks face significant challenges due to the lack of labeled data. Alternatively, with recent advancements in large-scale models, vision-langu…

Handling Domain Shifts for Anomalous Sound Detection: A Review of DCASE-Related Work

Kevin Wilkinghoff, Takuya Fujimura, Keisuke Imoto +3

When detecting anomalous sounds in complex environments, one of the main difficulties is that trained models must be sensitive to subtle differences in monitored target signals, wh…

Analysis and Extension of Noisy-target Training for Unsupervised Target Signal Enhancement

Takuya Fujimura, Tomoki Toda

Deep neural network-based target signal enhancement (TSE) is usually trained in a supervised manner using clean target signals. However, collecting clean target signals is costly a…
