Speak: A Toolkit Using Amazon Mechanical Turk to Collect and Validate Speech Audio Recordings

no code implementations LREC 2022 Christopher Song, David Harwath, Tuka Alhanai, James Glass

We present Speak, a toolkit that allows researchers to crowdsource speech audio recordings using Amazon Mechanical Turk (MTurk).

The Broad Impact of Feature Imitation: Neural Enhancements Across Financial, Speech, and Physiological Domains

no code implementations21 Sep 2023 Reza Khanmohammadi, Tuka Alhanai, Mohammad M. Ghassemi

Three different experiments are conducted in this study to test the applicability of imitating Tsallis entropy for performance enhancement: Bitcoin price prediction, speech emotion recognition, and chronic neck pain detection.

Feature Imitating Networks Enhance The Performance, Reliability And Speed Of Deep Learning On Biomedical Image Processing Tasks

1 code implementation26 Jun 2023 Shangyang Min, Hassan B. Ebadian, Tuka Alhanai, Mohammad Mahdi Ghassemi

Feature-Imitating-Networks (FINs) are neural networks that are first trained to approximate closed-form statistical features (e. g. Entropy), and then embedded into other networks to enhance their performance.

Nightly Automobile Claims Prediction from Telematics-Derived Features: A Multilevel Approach

no code implementations10 May 2022 Allen R. Williams, Yoolim Jin, Anthony Duer, Tuka Alhanai, Mohammad Ghassemi

This data is continuously collected and processed nightly into metadata consisting of mileage and time summaries of each discrete trip taken, and a set of behavioral scores describing attributes of the trip (e. g, driver fatigue or driver distraction) so we examine whether it can be used to identify periods of increased risk by successfully classifying trips that occur immediately before a trip in which there was an incident leading to a claim for that driver.

Fetal Gender Identification using Machine and Deep Learning Algorithms on Phonocardiogram Signals

no code implementations10 Oct 2021 Reza Khanmohammadi, Mitra Sadat Mirshafiee, Mohammad Mahdi Ghassemi, Tuka Alhanai

In this work, we apply common PCG signal processing techniques on the gender-tagged Shiraz University Fetal Heart Sounds Database and study the applicability of previously proposed features in classifying fetal gender using both Machine Learning and Deep Learning models.
