Analysis of a Deep Learning Model for 12-Lead ECG Classification Reveals Learned Features Similar to Diagnostic Criteria [PDF]

open access: yesIEEE journal of biomedical and health informatics, 2022
Despite their remarkable performance, deep neural networks remain unadopted in clinical practice, which is considered to be partially due to their lack of explainability. In this work, we apply explainable attribution methods to a pre-trained deep neural

Are Teachers Amenable to Increasing Students' Scope of Work in Doing Proofs? Estimating Teachers' Decision-Making Using a Diagnostic Classification Model

open access: yesJournal of Educational Research in Mathematics, 2020
We investigate teachers' decision making in contexts where they could choose to provide students more authentic experiences with proving. Specifically, we investigate their preferences to depart from norms about what proof problems to assign to students.

Rapid Diagnostic Algorithms as a Screening Tool for Tuberculosis: An Assessor Blinded Cross-Sectional Study [PDF]

open access: yes, 2012
Background: A major obstacle to effectively treat and control tuberculosis is the absence of an accurate, rapid, and low-cost diagnostic tool. A new approach for the screening of patients for tuberculosis is the use of rapid diagnostic classification ...

Prospects for the classification of mental disorders in women [PDF]

open access: yes, 2010
Many mental disorders show marked gender differences as regards prevalence, symptomatology, risk factors or course. Other disorders do per definition only occur in women - e.g. premenstrual dysphoric disorder (PMDD) - or are markedly influenced by female

Modeling Learner Heterogeneity: A Mixture Learning Model With Responses and Response Times

open access: yesFrontiers in Psychology, 2018
The increased popularity of computer-based testing has enabled researchers to collect various types of process data, including test takers' reaction time to assessment items, also known as response times. In recent studies, the relationship between speed

An Efficient Hybrid CNN Classification Model for Tomato Crop Disease

open access: yesTechnologies, 2023
Tomato plants are vulnerable to a broad number of diseases, each of which has the potential to cause significant damage. Diseases that affect crops substantially negatively impact the quantity and quality of agricultural products.

Classification of functional psychoses and its implication for prognosis: Comparison between ICD-10 and DSM-IV [PDF]

open access: yes, 2004
Background: The aim was to examine the agreement and differences between ICD-10 and DSM-IV in the classification of functional psychoses. Sampling and Methods: In a sample of 218 first-hospitalised patients, ICD-10 diagnoses were compared with DSM-IV ...

Pathological neural networks and artificial neural networks in ALS: diagnostic classification based on pathognomonic neuroimaging features

open access: yesJournal of Neurology, 2021
The description of group-level, genotype- and phenotype-associated imaging traits is academically important, but the practical demands of clinical neurology centre on the accurate classification of individual patients into clinically relevant diagnostic,
