A knowledge-driven vowel-based approach of depression classification from speech using data augmentation

1 code implementation27 Oct 2022 Kexin Feng, Theodora Chaspari

Following that, the depression is classified at the global-level from a group of vowel CNN embeddings that serve as the input of another 1D CNN ("depression CNN").

A few-shot learning approach with domain adaptation for personalized real-life stress detection in close relationships

1 code implementation27 Oct 2022 Kexin Feng, Jacqueline B. Duong, Kayla E. Carta, Sierra Walters, Gayla Margolin, Adela C. Timmons, Theodora Chaspari

The proposed metric learning is based on a Siamese neural network (SNN) that learns the relative difference between pairs of samples from a target user and non-target users, thus being able to address the scarcity of labelled data from the target.

Toward Knowledge-Driven Speech-Based Models of Depression: Leveraging Spectrotemporal Variations in Speech Vowels

1 code implementation5 Oct 2022 Kexin Feng, Theodora Chaspari

Explainability of the high-level information capturing the segment-by-segment decisions is further inspected for participants with and without depression.

Predicting the meal macronutrient composition from continuous glucose monitors

no code implementations23 Jun 2022 Zepeng Huo, Bobak J. Mortazavi, Theodora Chaspari, Nicolaas Deutz, Laura Ruebush, Ricardo Gutierrez-Osuna

We built a multitask neural network to estimate the macronutrient composition from the CGM signal, and compared it against a baseline linear regression.

Few-shot Learning in Emotion Recognition of Spontaneous Speech Using a Siamese Neural Network with Adaptive Sample Pair Formation

no code implementations7 Sep 2021 Kexin Feng, Theodora Chaspari

Leveraging the abundance of labelled speech data from acted emotions, this paper proposes a few-shot learning approach for automatically recognizing emotion in spontaneous speech from a small number of labelled samples.

A Siamese Neural Network with Modified Distance Loss For Transfer Learning in Speech Emotion Recognition

no code implementations4 Jun 2020 Kexin Feng, Theodora Chaspari

Our system use samples from the source data to pre-train the weights of proposed Siamese neural network, which are fine-tuned based on the target data.
