Query: Explainable Identification of Dementia from Transcripts using
  Transformer Networks   Alzheimer's disease (AD) is the main cause of dementia which is accompanied
by loss of memory and may lead to severe consequences in peoples' everyday life
if not diagnosed on time. Very few works have exploited transformer-based
networks and despite the high accuracy achieved, little work has been done in
terms of model interpretability. In addition, although Mini-Mental State Exam
(MMSE) scores are inextricably linked with the identification of dementia,
research works face the task of dementia identification and the task of the
prediction of MMSE scores as two separate tasks. In order to address these
limitations, we employ several transformer-based models, with BERT achieving
the highest accuracy accounting for 87.50%. Concurrently, we propose an
interpretable method to detect AD patients based on siamese networks reaching
accuracy up to 83.75%. Next, we introduce two multi-task learning models, where
the main task refers to the identification of dementia (binary classification),
while the auxiliary one corresponds to the identification of the severity of
dementia (multiclass classification). Our model obtains accuracy equal to
86.25% on the detection of AD patients in the multi-task learning setting.
Finally, we present some new methods to identify the linguistic patterns used
by AD patients and non-AD ones, including text statistics, vocabulary
uniqueness, word usage, correlations via a detailed linguistic analysis, and
explainability techniques (LIME). Findings indicate significant differences in
language between AD and non-AD patients.
