This paper provides an overview of string kernels. String kernels compare text documents by the substrings they contain. Because of high computational complexity, methods for approximating string kernels are shown. Several extensions for string kernels are also presented. Finally string kernels are compared to BOW.

Six Iranian accessions of Cucumis melo, including Inodorus, Cantalupensis, and Dudaim groups, were planted and then harvested at two harvesting stages including 21 and 28 days after anthesis for Dudaim group and 28 and 38 days after anthesis for Inodorus and Cantalupensis groups. At the time of harvest, we measured some quality parameters and appearance indices of fruits, such as the number of ...

Many kernels for discretely structured data in the literature are designed within the framework of the convolution kernel and its generalization, the mapping kernel. The two most important advantages to use this framework are an easy-to-check criteria of positive definiteness of the resulting kernels and efficient computation based on the dynamic programming methodology. On the other hand, the ...

We present Random Partition Kernels, a new class of kernels derived by demonstrating a natural connection between random partitions of objects and kernels between those objects. We show how the construction can be used to create kernels from methods that would not normally be viewed as random partitions, such as Random Forest. To demonstrate the potential of this method, we propose two new kern...

This research aims to understand the fractional order dynamics of deadly Nipah virus (NiV) disease. We focus on using piecewise derivatives in context classical and singular kernels power operators Caputo sense investigate crossover behavior considered dynamical system. establish some qualitative results about existence uniqueness solution proposed problem. By utilizing Newtonian polynomials in...

in order to determine the appropriate plant density in different planting dates for sweet corn cultivar ksc403su, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three planting dates (22 may, 5 june and 22 june) were assigned as main plots and three plant densities (65000...

Storage of Lime (Citrus aurantifolia L.) fruits, originally a tropical fruits, in low temperature confronts with several difficulties  due to the risk of chilling injury (CI). To develop an effective method aiming to  reduce CI, the effects of treatments containing 0, 0.5 and 1 Mg/lit brassinosteroids (BRs) and hot water (HW) including 20°C as control, 45 and 55°C for 30 minute on CI was studie...

Roasting nuts may alter their chemical composition leading to changes in their health benefits. However, the presence of testa may alleviate the negative effects of thermal treatments. Hence, this study aimed to explore the effects of roasting on kernel chemical quality and colour development of Canarium indicum and examine to what extent testa would protect kernels against damage from roasting...

training systems and calcium foliar application can improve apple fruits pigmentation by changing mineral compositions. in this study, effect of foliar application of calcium chloride with different concentrations (0, 0.75, 1.5 and 3 g l-1) over 2, 4 and 6 weeks before harvest time on fruit mineral nutrient composition and colour values of apple cvs. gala and delbarestival which trained in thre...
