  • The characteristicsof a vector are the magnitude, the orientation, and the sense. The magnitudeof a vector is speci®ed by a positive number and a unit having appropriate dimensions. No unit is stated if the dimensions are those of a pure number. The orientationof a vector is speci®ed by the relationship between the vector and given reference lines and=or planes. Thesenseof a vector is speci®ed by the order of two points on a line parallel to the vector. Orientation and sense together determine the directionof a vector.

  • We explore how active learning with Support Vector Machines works well for a non-trivial task in natural language processing. We use Japanese word segmentation as a test case. In particular, we discuss how the size of a pool affects the learning curve. It is found that in the early stage of training with a larger pool, more labeled examples are required to achieve a given level of accuracy than those with a smaller pool. In addition, we propose a novel technique to use a large number of unlabeled examples effectively by adding them gradually to a pool. ...

  • Generalized Vector Space Models (GVSM) extend the standard Vector Space Model (VSM) by embedding additional types of information, besides terms, in the representation of documents. An interesting type of information that can be used in such models is semantic information from word thesauri like WordNet. Previous attempts to construct GVSM reported contradicting results. The most challenging problem is to incorporate the semantic information in a theoretically sound and rigorous manner and to modify the standard interpretation of the VSM.

  • This paper proposes a framework for representing the meaning of phrases and sentences in vector space. Central to our approach is vector composition which we operationalize in terms of additive and multiplicative functions. Under this framework, we introduce a wide range of composition models which we evaluate empirically on a sentence similarity task. Experimental results demonstrate that the multiplicative models are superior to the additive alternatives when compared against human judgments. ...

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.

Examples of vectors are displacement, velocity and acceleration.

  • Vector notation and vector addition Graphical: a scalar multiplies an arrow. Indicate a vector’s direction by drawing an arrow with direction indicated by marked angles or slopes. The scalar multiple with a nearby scalar symbol, say F, as shown in figure 2.8b. This means F times a unit vector in the direction of the arrow. (Because F might be negative, sign confusion is common amongst beginners. Please see sample 2.1.) Combined: graphical representation used to define a symbolic vector.

  • Interactive curve modeling techniques and their applications are extremely useful in a number of academic and industrial settings. Specifically, curve modeling plays a significant role in multidisciplinary problem solving. It is extremely useful in various situations like font design, designing objects, CAD/CAM, medical imag- ing and visualization, scientific data visualization, virtual reality, object recogni- tion, etc. In particular, various problems like iris recognition, fingerprint recog- nition, signature recognition, etc.

  • There are a lot of references of rickettsioses acquired by travellers and considered imported diseases (McDonald et al., 1988; Bottieau et al. 2006; Freedman et al., 2006; Askling et al. 2009; Chen & Wilson, 2009; Jensenius et al., 2009; Stokes & Walters, 2009). Nowadays ticks cause most travel-associated rickettsioses. Ticks are considered to be one of the most important vectors of infectious diseases in the world, preceded only by mosquitoes. Therefore, tick-borne rickettsioses are endemic all over the world (Hechemy et al., 2006).

  • There are mainly four types of segmentation techniques, namely global thresholding, boundary-based segmentation, region-based segmentation, and mixed segmentation. Seeded Region Growing is an integrated method brought up by Adams and Bischof [4-13], in which few initial seeds are generated, and more similar neighboring regions are then combined to achieve region growing [14-21]. In addition, the method of unsupervised vector seeded region growing suitable for medical multi-spectral images was established.

  • The modular producer cell lines present several advantages: they are safer since integration of the vector within the packaging cell line was identified, the duration of the entire development process is much reduced as there is no need for screening and, in addition, production conditions are favorable due to the possibility of pre-adaptation of the master cell line to culture conditions and media. Thus, therapeutic virus production from bench to bedside becomes safer, faster, and cheaper (Coroadinha et al. 2010)....

  • Similarly to retroviral vectors, the design of lentiviral vector packaging systems has evolved to minimize the risk of RCPs generation towards maximum safety. Currently, three generations of lentiviral vectors are considered. The first-generation (Naldini et al. 1996) closely resembles the three plasmid packaging system of simple retroviruses, except for the fact that the gag-pol expression is driven by a heterologous promoter instead of the viral LTR; additionally, the gp120 HIV-1’s envelope was replaced by VSV-G’s.

The vector of covariates, xt, includes indicator variables for month of the year, day of the week, and hour of the day as well as interactions between weekends and hour of the day. In addition, xt includes weather variables including current and 1-hour lags of quartics in temperature, humidity, and wind speed. 14 Equation (1) is first estimated using least squares (OLS) for four different time windows rang- ing from 1986-1993 to 1989-1990.

  • Motivated by the recent interest in streaming algorithms for processing large text collections, we revisit the work of Ravichandran et al. (2005) on using the Locality Sensitive Hash (LSH) method of Charikar (2002) to enable fast, approximate comparisons of vector cosine similarity. For the common case of feature updates being additive over a data stream, we show that LSH signatures can be maintained online, without additional approximation error, and with lower memory requirements than when using the standard offline technique. ...

  • Arabic morphology is complex, partly because of its richness, and partly because of common irregular word forms, such as broken plurals (which resemble singular nouns), and nouns with irregular gender (feminine nouns that look masculine and vice versa). In addition, Arabic morphosyntactic agreement interacts with the lexical semantic feature of rationality, which has no morphological realization. In this paper, we present a series of experiments on the automatic prediction of the latent linguistic features of functional gender and number, and rationality in Arabic.

  • This paper proposes new algorithms to compute the sense similarity between two units (words, phrases, rules, etc.) from parallel corpora. The sense similarity scores are computed by using the vector space model. We then apply the algorithms to statistical machine translation by computing the sense similarity between the source and target side of translation rule pairs. Similarity scores are used as additional features of the translation model to improve translation performance.
