The ecology of social interactions in online and offline environments
The rise in online social networking has brought about a revolution in social relations. However, its effects on offline interactions and its implications for collective well-being are still not clear and are under-investigated. ... Read More >

Effective Capacity of Retransmission Schemes - A Recurrence Relation Approach
We consider the effective capacity performance measure of persistent- and truncated-retransmission schemes that can involve any combination of multiple transmissions per packet, multiple communication modes, or multiple packet c ... Read More >

SculptStat: Statistical Analysis of Digital Sculpting Workflows
Targeted user studies are often employed to measure how well artists can perform specific tasks. But these studies cannot properly describe editing workflows as wholes, since they guide the artists both by choosing the tasks and ... Read More >

Deep Learning Based Semantic Video Indexing and Retrieval
We share the implementation details and testing results for video retrieval system based exclusively on features extracted by convolutional neural networks. We show that deep learned features might serve as universal signature f ... Read More >

Certified Context-Free Parsing: A formalisation of Valiant's Algorithm in Agda
Valiant (1975) has developed an algorithm for recognition of context free languages. As of today, it remains the algorithm with the best asymptotic complexity for this purpose. In this paper, we present an algebraic specificatio ... Read More >

Non-overlapping matrices
Two matrices are said non-overlapping if one of them can not be put on the other one in a way such that the corresponding entries coincide. We provide a set of non-overlapping binary matrices and a formula to enumerate it which ... Read More >

Distributed Low Rank Approximation of Implicit Functions of a Matrix
We study distributed low rank approximation in which the matrix to be approximated is only implicitly represented across the different servers. For example, each of $s$ servers may have an $n \times d$ matrix $A^t$, and we may b ... Read More >

Log-Normal Matrix Completion for Large Scale Link Prediction
The ubiquitous proliferation of online social networks has led to the widescale emergence of relational graphs expressing unique patterns in link formation and descriptive user node features. Matrix Factorization and Completion ... Read More >

Categorization of Stringed Instruments with Multifractal Detrended Fluctuation A ...
Categorization is crucial for content description in archiving of music signals. On many occasions, human brain fails to classify the instruments properly just by listening to their sounds which is evident from the human respons ... Read More >
