Predicting depression can mitigate tragedies. Numerous works have been proposed so far using machine learning algorithms. This paper reviews publications from online electronic databases from 2016 to 2020 that use machine learning techniques to predict depression. The aim of this study is to identify important variables used in depression prediction, recent depression screening tools adopted, and the latest machine learning algorithms used. This understanding provides researchers with the fundamental components essential to predict depression. Fifteen articles were found relevant. We based our review on the systematic mapping study (SMS) method. Three research questions were answered through this review. We discovered that sixteen variables were deemed important by the literature. Not all of the reviewed literature utilizes depression screening tools in the prediction process. Nevertheless, from the five screening tools discovered, the most frequently used were hospital anxiety and depression scale (HADS) and hamilton depression rating scale (HDRS) for general population, while for literature targeting older population geriatric depression scale (GDS) was often employed. A total of twenty-two machine learning algorithms were identified employed to predict depression and random forest was found to be the most reliable algorithm across the publications.
This paper describes the process undertaken and criteria considered in acquiring a speech corpus of Malay language towards the development of humanoid storyteller. The speech corpus contains 464 speech sentences, 4,656 words and 9,584 syllables. Three children's short stories were recorded by 3 female storytellers, 1 male pr female speakers and 2 male speakers. The equipment specifications, recording procedures and speech annotations are described in detail in accordance to baseline work. The stories were recorded in two speaking styles that are neutral a Malay language storytelling corpus is not only necessary for the development of a storytelling text-to-speech (TTS) synthesis. It is also detrimental for natural language processing and speech recognition of Malay language, an under
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
