Information theoretic analysis of watermarking systems
… to the public in order to embed some extra information. The embedding should be transparent (i.e., the modified data should be similar to the original data) and robust (i.e., the information should be recoverable even if the data is modified further). In this thesis, we describe the …

Information-theoretic analysis of human-machine mixed systems
Many recent information technologies such as crowdsourcing and social decision-making systems are designed based on (near-)optimal information processing techniques for machines. However, in such applications, some parts of systems that process information are humans and so systems are affected by …

Detection- and Information -Theoretic Analysis of Steganography and Fingerprinting
Then, from an information-theoretic perspective, we derive the capacity and random-coding error exponent of perfectly secure steganography and public fingerprinting. For both games, a randomized stacked-binning scheme and a matched maximum penalized mutual information decoder are used to achieve …

An Information-Theoretic Analysis of Adherence to Physical Exercise Routines
… they will exercise. However, with the use of information entropy, a linear regression model, and the R<sup>2</sup> statistic we disprove this hypothesis. Instead, we find that the more a participant exercises, the less habitual they are with the time of day they exercise. Given how busy our …

An information-theoretic analysis of resampling in Sequential Monte Carlo
Sequential Monte Carlo (SMC) methods form a popular class of Bayesian inference algorithms. While originally applied primarily to state-space models, SMC is increasingly being used as a general-purpose Bayesian inference tool. Traditional analyses of SMC algorithms focus on their usage for …

Regularized Adaboost for RGBD video content identification
… three contributions. First, we provide an information theoretic analysis to a recently developed learning-based content identification (ID) algorithm, symmetric pairwise boosting (SPB). Second, we propose a regularized Adaboost algorithm, which tackles SPB’s implicit assumption that video …

Coding for random access in wireless networks
… random-access access becomes a challenge. Information theoretic analysis of such systems becomes imperative to understand the gap from optimality of the methods of random-access currently employed. In this thesis we discuss the trade-off between the required energy-per-bit to achieve a …

Intelligent antenna sharing in cooperative diversity wireless networks
… between the source and the destination. Information theoretic analysis of outage probability shows that our scheme achieves the same diversity-multiplexing gain tradeoff as achieved by more complex protocols, where coordination and distributed space-time coding for M relay nodes is …

Prosody Dependent Speech Recognition on American Radio News Speech
… and suprasegmental units of speech. We conduct information-theoretic analysis, proving that when prosody is modeled, better word recognition can be achieved through the interaction between the acoustic model and the language model. We conduct detailed experiments to determine the set of …

Wireless Communication in Vehicles
… parameters which are sufficient to perform an information theoretic analysis to lower bound the capacity of the in-vehicle channel. For typical operating conditions, it is found that the channel capacity is approximately equal to that of the same channel with perfect channel state information …

Learning compact hashing codes for large-scale similarity search
… maximization is a novel hashing framework with theoretical guarantee and great flexibility in designing hashing algorithms for various scenarios. The regularized Adaboost algorithm is to learn and extract binary hash codes (fingerprints) of time-varying content by filtering and quantizing …

Capacity of Gaussian noise channels with side information and feedback
… The transmitters usually have some form of information regarding the channel behavior. The main question of interest is to determine how to best use this information in order to increase the transmission rates, decrease the error probability and conserve resources. In this thesis, we present …

Design and Analysis of Decoy Systems for Computer Security
