To make judicious budget and resource allocation decisions, it is essential to understand the characteristics and performance of keywords used by target shoppers. Taking the approach of understanding consumers’ information needs, we construct a goal-related keyword characterization framework. Most search keywords exhibit more than one of the following characteristics retailer specific, brand sp...

Can we summarize multi-category data based on user preferences in a scalable manner? Many utility functions used for data summarization satisfy submodularity, a natural diminishing returns property. We cast personalized data summarization as an instance of a general submodular maximization problem subject to multiple constraints. We develop the first practical and FAst coNsTrained submOdular Ma...

The purpose of the study was to identify the constrains affecting urban agriculture in Tehran, Iran. The statistical population of this study consisted of city dwellers within the 22 municipal districts of Tehran out of which 320 individuals were selected as the sample of the study. Cochran’s formula was used to determine the sampling size based on stratified sampling method. A panel of experts...

Quantum low-density parity-check (LDPC) codes are an important class of quantum error correcting codes. In such codes, each qubit only affects a constant number syndrome bits, and bit relies on some qubits. Constructing LDPC is challenging. It open problem to understand if there exist good i.e. with rate relative distance. Furthermore, techniques perform fault-tolerant gates poorly understood. ...

Compilers perform static analysis prior to applying an optimization. The analysis results are typically not very precise, however, as a compiler operates with a strict time budget, which constrains reasoning. In this paper, we explore a new direction: using information gathered by external sound static analysis tools to augment the internal compiler reasoning, and investigate whether this leads...
