+Kernel methods, which are among the most flexible and influential tools in
+machine learning with applications in virtually all areas of the field, rely
 on high-dimensional feature spaces in order to construct powerfull classifiers or
 regressors or clustering algorithms. The main drawback of kernel methods
 is their prohibitive computational complexity. Both spatial and temporal complexity
  is at least quadratic because we have to compute the whole kernel matrix.
 
 One of the popular way to improve the computational scalability of kernel methods is
 to approximate the feature map impicit behind the kernel method. In practice,
