Acoustic Model Adaptation For Reverberation Robust Automatic Speech Recognition
… artifacts mostly noise compensation techniques have been proposed. As a consequence, the problem of reverberation has received relatively less attention. Lately, some techniques have emerged which are specifically tailored for compensating the effects of reverberation. Nevertheless, …

Applications of broad class knowledge for noise robust speech recognition
This thesis introduces a novel technique for noise robust speech recognition by first describing a speech signal through a set of broad speech units, and then conducting a more detailed analysis from these broad classes. These classes are formed by grouping together parts of the acoustic signal …

Techniques to Mitigate the Effects of Congenital Faults in Processors
… novel framework that shows how microarchitecture techniques can mitigate variation-induced errors and even trade them off for power and processor frequency. Several such techniques are analyzed---in particular, a high-dimensional dynamic-adaptation technique that maximizes performance when there …

Simulation and Assessment of Long-Term Stormwater Basin Performance under Real-Time Control Retrofits
The use of real-time control (RTC) as an adaptation technique for improving existing stormwater systems has been gaining attention in recent years for its ability to enhance water quality and quantity treatment. A case study RTC retrofit of seven existing detention basins was simulated for a small …

Combating fake news with adversarial domain adaptation and neural models
… are then supplemented with an adversarial domain adaptation technique, which helps the models overcome dataset size limitations. We test the performance of these models by using the Fake News Challenge (FNC) [Pomerleau and Rao, 2017], the Fact Extraction and VERification (FEVER) [Thorne et al., …

Link adaption with limited feedback for future wireless networks
Link adaptation technique (LAT) is one of the radio resource management (RRM) functions necessary for future wireless network to enhance the system capacity and provide an adequate quality of service to the end users. LAT requires knowledge of users’ received signal-to-noise ratio so that …

Robust Domain Adaptation Using Active Learning
… way to mitigate this problem is to use domain adaptation techniques; these techniques build a new model on the unlabeled test dataset (target dataset) by transferring information from a related but labeled training dataset, (source dataset) even when their underlying distributions are …

Attribution-based parametric insurance: towards affordable premiums
… parametric insurance has been recognized as an adaptation technique to compensate farmers for economic losses from extreme weather events. The insurance can be either private or sovereign. African Risk Capacity Insurance (ARC Ltd) offers the latter to African countries against drought events …

Greediness control algorithm for multimedia streaming in wireless local area networks
… of the streaming processes reliance on rate adaptation engines based on congestion avoidance mechanisms, that try to obtain as much bandwidth as possible from the limited network resources. These upper transport layer mechanisms have no knowledge of the media which they are carrying and as a …

Self-adaptation via concurrent multi-action evaluation for unknown context
… ability of concurrent multi-action evaluation technique to performance tune a database when performance is regressed for an unknown reason. The second implementation demonstrated the ability of the framework to correctly determine the threshold price to be used in a name-your-own-price channel …

Temporal and spatial contextual modulation of walking direction in biological motion
… – point light animations. Chapter 2 uses an adaptation technique to investigate the sensory coding of perceived walking direction, and finds that adaptation to a specific walking direction results in repulsive perceptual aftereffects. The observed tuning profiles are well explained by a …
