DeepBlues@LT-EDI-ACL2022: Depression level detection modelling through domain specific BERT and short text Depression classifiers

no code implementations LTEDI (ACL) 2022 Nawshad Farruque, Osmar Zaiane, Randy Goebel, Sudhakar Sivapalan

In addition we can use short text classifiers to extract relevant text from the long text and achieve slightly better accuracy, albeit, trading off with the processing time for extracting such excerpts.

Safety Implications of Explainable Artificial Intelligence in End-to-End Autonomous Driving

no code implementations18 Mar 2024 Shahin Atakishiyev, Mohammad Salameh, Randy Goebel

The end-to-end learning pipeline is gradually creating a paradigm shift in the ongoing development of highly autonomous vehicles, largely due to advances in deep learning, the availability of large-scale training datasets, and improvements in integrated sensor devices.

Depression Symptoms Modelling from Social Media Text: A Semi-supervised Learning Approach

no code implementations6 Sep 2022 Nawshad Farruque, Randy Goebel, Sudhakar Sivapalan, Osmar Zaiane

In our work, we describe a Semi-supervised Learning (SSL) framework which uses an initial supervised learning model that leverages 1) a state-of-the-art large mental health forum text pre-trained language model further fine-tuned on a clinician annotated DSD dataset, 2) a Zero-Shot learning model for DSD, and couples them together to harvest depression symptoms related samples from our large self-curated Depression Tweets Repository (DTR).

A comprehensive empirical analysis on cross-domain semantic enrichment for detection of depressive language

no code implementations24 Jun 2021 Nawshad Farruque, Randy Goebel, Osmar Zaiane

We start with a rich word embedding pre-trained from a large general dataset, which is then augmented with embeddings learned from a much smaller and more specific domain dataset through a simple non-linear mapping mechanism.

An Introduction to Deep Visual Explanation

no code implementations26 Nov 2017 Housam Khalifa Bashier Babiker, Randy Goebel

The practical impact of deep learning on complex supervised learning problems has been significant, so much so that almost every Artificial Intelligence problem, or at least a portion thereof, has been somehow recast as a deep learning problem.
