In this two-hour workshop, we propose leading a discussion of an important, yet underinvestigated, facet of entrepreneurial communication: pitching. Specifically, we will discuss formal pitching, storytelling, and written elements of the pitch. We will do this by drawing on our own research, other published research, rhetorical theory, management theory, and our experience. Audience members will learn...
The recent attentions on video analysis have led to the extensive enhancement of computer vision technologies. However, it is still necessary to closely monitor the results of video analysis by human operators. This paper introduces a trajectory-based scene retrieval system that can help human operators look closely at desired scenes based on a trajectory query. The system includes the index and mapper...
In software projects, there is a data repository which contains the bug reports. These bugs are required to carefully analyse and resolve the problem. Handling these bugs humanly is extremely time consuming process, and it can result the deleying in addressing some important bugs resolutions. To overcome this problem, researchers have introduced many techniques. One of the commonly used algorithm...
Space-filling curves (SFCs) are straightforward and efficient methods for a sparse space clustering. They are utilized in research areas like classification, computer vision, computer graphics and/or machine learning. Most of the SFCs are based on a regular orthogonal grid. Generally, a hierarchical properties of Quad-trees (2D) or Octrees (n-dimensional) are utilized for a vertex hashing. However,...
In this paper, we propose a multiversion index utilizing key features of SSDs (solid state drives). SSDs have many advantages, e.g., fast read/write performance, high energy efficiency, and non-volatility. Thus, SSDs have been considered for several years as a promising alternative to HDDs (hard disk drives). Many studies have made progress in optimizing and modifying HDD-based database management...
P2P networks constitute the foundation for many scalable and fault-tolerant applications. These networks may consist of millions of peers due to their decentralized design. While each peer advertises the same service interface, the actual data provided by common large-scale P2P applications often yields an imbalance, i.e., particular peer subsets are more frequently contacted than the rest of the...
Assessing E-commerce web sites quality is essential not only to have recommendations for improvement but also to make comparisons with competitors. In this paper, the aim is to know the best criteria for the evaluation and obtain a weight for them using fuzzy Analytic Network Process (fuzzy ANP). The subjective judgments of the decision maker are expressed by fuzzy numbers. The decision making problem...
A novel evaluation model, incorporating Theil entropy into TOPSIS, is employed for investigating Chinese high-tech innovation capacity at provincial level. More specifically, the innovation capacity evaluation in high-tech industries is viewed as a Multi-Criteria Decision Analysis (MCDA) problem. The weights of the indicators are determined by the Theil entropy analysis, and the regions are ranked...
Nowadays many researches have focused on the Affinity Propagation (AP) algorithm for community detection for its advantages of near-linear complexity and no prerequisite for any object function or cluster number. In view of different influences from common neighbors, we propose an improved Affinity Propagation algorithm which is based on adjacency matrix and considers self-similarity and similarity...
The Medical Subject Headings (MeSH) term search is typical data-gathering method in biomedical text mining. However, it has two problems: the allocation delay of the MeSH term and missing valuable literature sources. Since MeSH term allocation is performed by a human being, the allocation process has delay. In addition, even if a literature source was allocated with a MeSH term, there is a still the...
When traditional sample selection methods are used to compress large data sets, the computational complexity turns out to be very high and it is really time consuming. To avoid these shortcomings, we propose a new method to select samples based on non-stable cut points. With the basic characteristic of convex function that its extreme values occur at the endpoints of intervals, the method measures...
A comprehensive evaluation model of enterprise's partner selection on UIC is established by use of Analytical hierarchical process (AHP) and Grey Fuzzy Evaluation Method. The evaluation index system is built through literature review and expert interview, and then the weight of each index is determined by AHP and the reasonable conversion from qualitative to quantitative is acquired through the application...
The success or failure of a construction project depends largely on the contractor's performance since they are responsible for important activities in the building process. In this way, it is necessary to monitor the performance of the contractors who already working with the organization to control failures during the development of work. Due the complexity and necessity of considering various criteria...
In recent years, with the rapid spread of SNS, communication via social networks has become very active. Twitter users transmit information by posting messages, called Tweets, of fewer than 140 characters. Using a feature called Follow, users can obtain information posted by follow user according to their own interests. When using Twitter, it is difficult for users to find appropriate users to follow...
MapReduce is a parallel framework which has been widely adopted for conducting large-scale data analytics. In cases where analysis of multiple millions of books must be analyzed using federally funded high performance computing (HPC) resources, the framework fails to port directly. We propose a solution that builds off of MapReduce for use on a HPC system that preserves the key-value semantics of...
We consider a setup in which Alice selects a pdf ƒ from a set of prescribed pdfs P and sends a prefix-free codeword W to Bob in order to allow him to generate a single instance of the random variable X ∼ ƒ. We describe a universal coding scheme for this setup and establish an upper bound on the expected codeword length when the pdf ƒ is bounded, orthogonally concave (which includes quasiconcave pdf),...
The large-system decoupling property of a MAP estimator is studied when it estimates the i.i.d. vector x from the observation y = Ax + z with A being chosen from a wide range of matrix ensembles, and the noise vector z being i.i.d. and Gaussian. Using the replica method, we show that the marginal joint distribution of any two corresponding input and output symbols converges to a deterministic distribution...
This work studies the Pliable Index CODing problem (PICOD), a variation of the classical index coding problem where a client is satisfied if it can successfully decode at least one massage not present in its side information set. PICOD models ‘content-type coding’ applications, such as web searches. PICOD significantly differs from classical index coding (where each client desires a specific message...
Caching is an effective way to reduce peak-hour network traffic congestion by storing some contents at user's local cache. Maddah-Ali and Niesen (MAN) initiated a fundamental study of caching systems by proposing a scheme (with uncoded cache placement and linear network coding delivery) that is provably optimal to within a factor 4.7. In this paper, when the cache contents and the user demands are...
Recently, the study of the skyline and its variants has received considerable attention in various applications that require decision making and personalized services. The skyline is essentially a set of the most interesting (not dominated) tuples in the queried database. They are based on the concept of Pareto dominance. The skyline computation may lead to two scenarios: either (i) a huge number...
