  • Stochastic gradient descent (SGD) uses approximate gradients estimated from subsets of the training data and updates the parameters in an online fashion. This learning framework is attractive because it often requires much less training time in practice than batch training algorithms. However, L1-regularization, which is becoming popular in natural language processing because of its ability to produce compact models, cannot be efficiently applied in SGD training, due to the large dimensions of feature vectors and the fluctuations of approximate gradients. ...

  • What-if models of pavement management analysis such as RTIM, HERS and HDM-4 predict the consequences of different maintenance options to be tested that are specified exogenously. Therefore, although they are often used to “optimize” maintenance options, they are not optimizing them in its true sense; they are merely used to find the best options among those tested. Since there are usually infinite numbers of options, it is impossible to exhaust all of them and only suboptimal optimizers are found.

  • First and foremost, HTML5 includes redefinitions of existing markup elements, and new elements that allow web designers to be more expressive in the semantics of their markup. Why litter your page with divs when you can have articles, sections, headers, footers, and more? The term “HTML5” has additionally been used to refer to a number of other new technologies and APIs. Some of these include drawing with the element, offline storage, the new and elements, drag-and-drop functionality, Microdata, embedded fonts, and others.

  • Using the gradient method, element concentrations within the lichen are usually observed to increase as the distance to the suspected source decreases. Gough and Erdman (1977) used linear regression to evaluate the relationship between distance from a coal fired power plant and metal levels in Xanthoparmelia chlorochroa. However, as Puckett (1988) points out, concentrations of many elements will not reach zero at large distances from pollution sources because they have essential nutritional roles or are normal components of the lichen when growing in its natural environment.

  • NF-jB essential modulator (NEMO) plays an essential role in the nuclear factor jB (NF-jB) pathway as a modulator of the two other subunits of the IjB kinase (IKK) complex, i.e. the protein kinases, IKKa and IKKb. Previous reports all envision the IKK complex to be a static entity. Using glycerol-gradient ultracentrifugation, we observed stimulus-dependent dynamic IKK complex assembly.

  • The paper presents a systematic approach to find optimal maintenance strategies for pavement management systems by using the World Bank’s Highway Development and Management System (HDM-4) combined with gradient methods proposed by Tsunokawa et al (2005). The optimal maintenance strategy is defined as the set of optimal maintenance options corresponding to different traffic levels and various initial pavement conditions, which minimizes the sum of agency costs and road user costs in present value or maximizes the net benefit to society over an analysis period.

  • The recent literature on health economics has shown a keen interest in the mea- surement of health inequality and in its determinants. One of the more persistent and salient findings1 is the existence of a “health-income gradient”, in the sense that health tends to be associated positively with incomes. A seemingly natural corollary is that health policy might usefully take place through income redistri- bution and a general improvement in living standards.

  • Lichens are long-lived and can be monitored, field conditions permitting, in any season. Many lichens have extensive geographical ranges, allowing study of pollution gradients over large areas. These properties make them useful for spatial and temporal evaluation of pollutant accumulation in the environment. Epiphytic lichens (those that grow on trees or plants) are often best suited to the study of air pollution effects on lichen communities, lichen growth or physiology, and to the study of pollutant loading and distribution.

  • Assume that gi (x) = 1 (hence gk (x) = 0, k = i), update the expert i based on output error. Update gating network so that gi (x) is even closer to unity. Alternatively, a batch training method can be adopted: 1. Apply a clustering algorithm to cluster the set of training samples into n clusters. Use the membership information to train the gating network. 2. Assign each cluster to an expert module and train the corresponding expert module. 3. Fine-tune the performance using gradient-based learning. Note that the function of the gating network is to partition the feature...

  • It is beyond the scope of this chapter to review in detail the different methods of detection, two published papers by Paneleaukou et al (2009), and Fehm et al (2005) have extensively reviewed the pros and cons of the different detection methods. In summary, PCR methods have a high rate of false positive results, density gradient centrifugation may be associated with increased lost of circulating cells whereas immunomagnetic separation may not recognize tumor cells which do not express EpCAM and does not differentiate between malignant and benign prostate cells.
