Embedding Networks: Node and Graph Level Representations
Graph neural networks gained significant attention for graph representation and classification in the machine learning community. For graph classification, different pooling techniques are introduced, but none of them has ...
Safe Operating Area Reliability of AlGaN/GaN High Electron Mobility Transistors (HEMTs)
Gallium Nitride (GaN) based high electron mobility transistors (HEMTs) are extensively
considered for power switching and RF applications by the virtue of their unique
properties. However, despite of its attractive ...
Spatial Analysis and Reconstruction of Reverberant Speech
Speech signal includes the spoken message and a lot more information such as speaker emotion, identity, language, speaking location characteristic etc., which makes the human interaction lively, desirable and more useful. ...
Kernel-Based Image Filtering: Fast Algorithms and Applications
Image filtering is a fundamental preprocessing task in computer vision and image processing.
Various linear and nonlinear filters are routinely used for enhancement, upsampling, sharpening,
reconstruction, etc. The focus ...
Devanagari Online Handwritten Character Recognition
In this thesis, a classifier based on local sub-unit level and global character level representations
of a character, using stroke direction and order variations independent features, is developed
for recognition of ...
On Learning and Lower Bound Problems Related to the Iterated Matrix Multiplication Polynomial
The iterated matrix multiplication polynomial (IMM) of width w and length d is the 1x1 entry in the product of d square matrices of size w. The w^2d entries in the d matrices are distinct variables. In this thesis, we study ...
A Method of Designing Museum Services Handling System for Ubiquitous Visitors
Advances in mobile computing technologies have enabled the personal ubiquitous computing environment for ubiquitous visitors. In the case of museum services, a ubiquitous visitor is free to access his/her interested exhibit ...
Transient Vector Estimator Based High Dynamic Performance Control and Kalman Filter based Self Commissioning of Induction Motor Drives for Electric Vehicle Applications
Induction machine, the work horse of the industry, has been widely used in industrial
drives. The most common and efficient way to control the speed of induction machine is
with variable frequency drives. The variable ...
AlGaN/GaN Heterojunction Based Hall Sensors for Magnetic Field Sensing over Wide Temperature Range
Hall sensor has proved to be an attractive solution for sensing requirements in electric
machines for direct measurement of fields or indirect estimation of physical quantities
such as current, speed and torque. Current ...
Algorithms for Social Good in Online Platforms with Guarantees on Honest Participation and Fairness
Recent decades have seen a revolution in the way people communicate, buy products, learn new things, and share life experiences. This has spurred the growth of online platforms that enable users from all over the globe to ...
