Redundant Information And Predictable Stock Price Returns
How well do investors distinguish information that already is priced from genuinely novel and ex- clusive private information? This paper examines whether investors misweight information that already is in stock prices (“redundant information”) in making their trading decisions, and whether this …

Aging and Referential Communication: Insights from Interactions with Artificial Agents
… that although older speakers produced more redundant information than younger speakers, they were similar in terms of performance measures (speech onset latency, speech rate, fluency). Intriguingly, effects were similar regardless of addressee type. The next study examined potential …

Embedding and latent variable models using maximal correlation
… orthogonal to all other dimensions to not encode redundant information. Intuitively, we want to map objects that frequently co-occur to be close in the embedding space. However, often there are unobserved or under-sampled pairs that skew the result. We derive simple regularization techniques to …

An ERP Study to Investigate Age-Related Differences in Sensory Gating and Auditory Processing
… that inhibits neurological responses to redundant information. Although studied within clinical populations, sensory gating has rarely been investigated with respect to aging. The present research investigated age-related changes in auditory sensory gating using electroencephalography and …

Rats' (Rattus norvegicus) Encoding and Retrieval of Spatial and Non-Spatial Environmental Features in a Foraging Task
… they can use a landmark's non-spatial featural information. The objectives of this thesis were: 1) to determine the conditions under which rats process information separately or simultaneously; 2) to determine how rats process stimuli when previously fixed information becomes more variable; 3) …

Feature Selection Using Genetic Algorithms for Human Gait Recognition
… goal is achieved by discarding irrelevant and redundant information which affects both the classifier's performance and system's efficiency. Traditional gait recognition systems have mostly been evaluated without considering the most relevant features. In this study, we are going to investigate …

Eliminating Redundant and Less-informative RSS News Articles Based on Word Similarity and A Fuzzy Equivalence Relation
The Internet has marked this era as the information age. There is no precedent in the amazing amount of information, especially network news, that can be accessed by Internet users these days. As a result, the problem of seeking information in online news articles is not the lack of them but being …

Does the redundancy principle of multimedia learning hold in the secondary science classroom?
… has identified circumstances when eliminating redundant information improved learning outcomes, but those studies were conducted in laboratory and workplace settings rather than secondary science classrooms. Therefore the goal of this study is to further clarify the boundaries of the redundancy …

An Identity and Certificate Manager
… within applications. The protocol avoids sending redundant information by remembering what information has been sent to whom; this feature is critical in low-bandwidth networks. The protocol also implements a robust fail-over mechanism for handling out-of-sync situations. To illustrate the …

Intraserial repetition effects upon levels of cognitive processing
… in the set. The results were supportive of an information reduction model in which stimulus sets containing repetition are reduced. Set reduction occurs more readily for the adjacent repetition condition due to the identical items being perceptually distinct. Support for a trace strength model …

Speech perception in a sparse domain
… dynamic range of hearing. Thus there is an information bottleneck, whereby these devices must transform acoustical sounds with a large dynamic range into the smaller range of hearing impaired listeners. The limited dynamic range problem can be thought of as a communication channel with …

Variational Autoencoders for Discovering Influential Latent Factors
… latent factors trained could potentially contain redundant information. In this thesis, we propose to apply VAEs as an unsupervised technique (i.e., in the absence of any external metadata) to investigate the extent to which we can discover a disentangled representation of tabular data and use …

An investigation of digital image compression techniques
By its nature, digital image data contains redundant information which, if removed, can reduce the amount of bandwidth required to transmit it, or reduce the space required to store it. In this thesis the characteristics of image data that give rise to redundancy, and one technique that can be used …

Probabilistic models for multi-view semi-supervised learning and coding
… with the relatively large amount of potentially redundant information transmitted by each sensor or modality (i.e., view). We investigate and develop novel multi view learning algorithms capable of learning from semi-supervised noisy sensor data, for automatically adapting to new users and …

A Bandwidth-Conserving Architecture for Crawling Virtual Worlds
… interaction that is co-operative and exploits information about 3D objects in the virtual world. Our approach supports analyzing redundant information crawled from virtual worlds in order to decrease the amount of data collected by crawlers, keep search engine collections up to date, and …

A novel technique for phased array receivers based on an economic sampling scheme
… factor of $N$ (Number of antennas), as they use redundant information. In this thesis, a novel phased receiver, based on an economic sampling scheme is proposed. All the elements in an array receive a common information (signal amplitude) and a unique information (relative delay between …

An Examination of the Factors Affecting State and District Participation in the Voluntary National Test in 4th-Grade Reading
… reading assessments as providing additional or redundant information about student achievement. Whereas some assessment directors, particularly in states, would use the VNTR as a benchmark for evaluating (a) their reading frameworks and assessments against the VNTR/NAEP framework and (b) the …

ENHANCED COMPUTATION TIME FOR FAST BLOCK MATCHING ALGORITHM
… idea of compression techniques is to remove the redundant information that exists in the video sequences. Motion compensated predictive coding is the main coding tool for removing temporal redundancy of video sequences and it typically accounts for 50-80% of the video encoding complexity. This …

The use and application of performance metrics with regional climate models
