A Federated Learning Framework For Medical Data
(2021-05-05)
This thesis investigates the Federation of Medical Machine Learning Models. Medical data
is by its very nature sensitive - which makes the free sharing of medical information difficult.
This data often contains very useful ...
Novel Ultrasound Imaging Methods for the Characterization of Tissue Microvascular Networks
(2021-04-27)
The structure and function of tissue microcirculation are critical in most major disease
developments and in the patient-specific treatment response. Adequate quantitative
characterization of tissue microvasculature may ...
Towards Hidden Backdoor Attacks on Natural Language Processing Models
(2021-05-05)
Over the years, machine learning techniques have been used in a wide variety of security
sensitive applications due to the high reliability and accuracy of its results. But recent
findings in the domain of adversarial ...
Transfer Learning and Distance Metric Learning in Non-stationary Environments
(2021-03-03)
The development of various online platforms such as social media provide users platforms
to share their thoughts, feedback and their daily lives. With the widespread of microblogs
such as Twitter and the tremendous increase ...
Enhancing Classification and Retrieval Performance by Mining Semantic Similarity Relation from Data
(2021-02-12)
When describing unstructured data, e.g., images and texts, humans often resort to similarity
defining the characteristics of these data in relative terms rather than absolute terms. The
subtle differences between such data ...
Super-Resolution Ultrasound Imaging of Microvascular Networks
(2021-05-03)
Under development in a pre-clinical setting, super-resolution ultrasound (SR-US) imaging brings
up to a ten-fold improvement in ultrasound (US) resolution. It can image microvascular changes
in various disease processes ...
Applications of the Multi-Constraint Most Probable Explanation Problem
(2021-05-03)
Probabilistic models are often used in practice to represent and reason about uncertainty. A
key reasoning task over them is finding the most probable assignment to all the unobserved
variables given observations. This ...
Personalization of Noise Reduction and Compression for Hearing Enhancement
(2021-03-02)
Noise reduction and dynamic range compression constitute two main signal processing modules
for hearing enhancement in modern digital hearing aid devices. This dissertation covers
personalization solutions for both of these ...
Gestural Coordination of Modern Greek Consonant Clusters : Kinematic Analysis and Use of Supervised Learning Methods
(2021-07-01)
Consonant clusters are groups of consonants not interrupted by a vowel and are produced by a
set of articulatory gestures that coordinate in time. Little is known about which factors affect the
temporal overlap of these ...
Fairness-Aware Multi-Task and Meta Learning
(2021-07-22)
Nowadays, machine learning plays an increasingly prominent role in our life since decisions
that humans once made are now delegated to automated systems. In recent years, an increasing number of reports stated that human ...
