Neural Latent Aligner: Cross-trial Alignment for Learning Representations of Complex, Naturalistic Neural Data

no code implementations12 Aug 2023 Cheol Jun Cho, Edward F. Chang, Gopala K. Anumanchipalli

The proposed framework learns more cross-trial consistent representations than the baselines, and when visualized, the manifold reveals shared neural trajectories across trials.

Deep Speech Synthesis from MRI-Based Articulatory Representations

1 code implementation5 Jul 2023 Peter Wu, Tingle Li, Yijing Lu, Yubin Zhang, Jiachen Lian, Alan W Black, Louis Goldstein, Shinji Watanabe, Gopala K. Anumanchipalli

Finally, through a series of ablations, we show that the proposed MRI representation is more comprehensive than EMA and identify the most suitable MRI feature subset for articulatory synthesis.
