Generalizable No-Reference Image Quality Assessment: Multi-Modal Models and Human Preference Analysis for AI Generated Images
One of the major challenges in no-reference (NR) image quality assessment (IQA) is the ability to generalize to diverse quality assessment applications. Recently, multi-modal vision-language models have been found to be ... -
Generalized Likelihood Ratio Procedures for Early Detection of Machine Faults
Condition monitoring of industrial machinery is an important example of a cyber physical system (CPS), in which measurements on a machine, transmitted over a wireless network, are used to make inferences about the health ... -
Generation of Modulated Microwave Signals using Optical Techniques for Onboard Spacecraft Applications
(2017-12-01)This thesis deals with optical synthesis of unmodulated and modulated microwave signals. Generation of microwave signals based on optical heterodyning is discussed in detail. The effect of phase noise of laser on heterodyned ... -
Graph Neural Networks with Parallel Local Neighborhood Aggregations
Graph neural networks (GNNs) have become very popular for processing and analyzing graph-structured data in the last few years. Using message passing as their basic building blocks that aggregate information from neighborhoods, ... -
Grassmannian Fusion Frames for Block Sparse Recovery and Its Application to Burst Error Correction
(2018-05-01)Fusion frames and block sparse recovery are of interest in signal processing and communication applications. In these applications it is required that the fusion frame have some desirable properties. One such requirement ... -
Group Testing: A Probably Approximately Correct Analysis and Recovery Algorithms for pooled RT-qPCR
The goal of group testing, also called pool testing, is to successfully identify a set of k defectives from a population of n items using only m (< n) group tests. In each group test, a subset of the n items is tested ... -
Guessing And Compression : A Large Deviations Approach
(2011-04-01)The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ... -
High Dimensional Quantum Information Technology Using Photonics: Protocol Development and Implementation Schemes
This thesis explores the realm of high-dimensional quantum information processing through the lens of photonics, focusing on developing and implementing quantum technologies based on d-level quantum systems known as qudits. ... -
High-k Dielectrics For Metal-Insulator-Metal Capacitors
(2016-11-23)Metal-insulator-metal (MIM) capacitors are used for analog, RF, and DRAM applications in ICs. The International Technology Roadmap for Semiconductors (ITRS) specifies continuing increase in capacitance density (> 7 fF/ ... -
High-Rate And Information-Lossless Space-Time Block Codes From Crossed-Product Algebras
(2007-10-23)It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. It has been shown that coding across both spatial and temporal ... -
High-rate MSR Codes, Interior-point Regenerating Codes, and Codes with Hierarchical Locality
Given the breath-taking pace at which the amount of data being generated on a daily basis is growing, and the keen desire to extract information from this data, there is strong interest within the storage industry, at ... -
How are visual object representations organized and used to perform tasks ?
We rely heavily on vision for our daily activities, and around 40% of our brain is dedicated to vision. It is known that during a visual task, the visual information falling on the retina is processed in a hierarchy of ... -
Hybrid Electromagnetic Solvers for EMIEMC
With advances in technology and increased design complexity in the automotive industry, Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) issues are becoming increasingly important. An accurate ... -
A Hybrid Knowledge-Based System for Process Plant Fault Diagnosis
(Indian Institute of Science, 2005-03-11)Knowledge-Based Systems (KBSs) represent a relatively new programming approach and methodology that has evolved and is still evolving as an important sub-area of Artificial Intelligence (AI) research. The most prevalent ... -
Hypothesis Testing under Communication Constraints - Theory and an Application in IoT
Applications in the Internet of Things (IoT) often demand enabling low-compute devices to perform distributed inference and testing by communicating over a low bandwidth link. This gives rise to a plethora of new problems ... -
Imitation Learning Techniques for Robot Manipulation
Robots that can operate in unstructured environments and collaborate with humans play a major role in raising productivity and living standards as societies age. Unlike the robots currently used in industrial settings for ... -
Improved GMM-Based Classification Of Music Instrument Sounds
(2009-03-19)This thesis concerns with the recognition of music instruments from isolated notes. Music instrument recognition is a relatively nascent problem fast gaining importance not only because of the academic value the problem ... -
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ... -
Index Coding, Error Correcting Index Codes And Matroids
In the problem of index coding, there is a central source sending messages to a set of receivers which demand messages over a noiseless broadcast channel. Each receiver knows a subset of messages which is referred to as ...
