Applying Machine Learning Techniques to Lithium-ion Cell Research
(2021-03-08)Progress in lithium-ion cells research is largely a matter of determining which aspect of the cell’s design and operation will lead to longer life, higher energy-density, and lower costs. These attributes can easily be ... -
Author Style Analysis in Text Documents Based on Character and Word N-Grams
(2017-04-27)We describe our research on text analytics methods for detecting differences and similarities in the style of authors of text documents. Automatic methods for analyzing the written style of authors have applications in ... -
Authorship Attribution using Written and Read Documents
(2019-08-07)In Authorship Attribution (AA), a task of identifying the author on an unseen document, it is often hard to obtain large amounts of training text written by an author. In our research, we analyze the influence of the size ... -
Automated Labour Detection Framework to Monitor Pregnant Women with a High Risk of Premature Labour
(2022-02-22)It is estimated that more than 1 in 10 babies are born prematurely worldwide. Babies that survive premature birth are more likely to face lifelong health-related disabilities. By monitoring uterine contractions, labour can ... -
Biologically Informed Feature Selection in Large Scale Genomics
