Abstract: An arbitrary directional touch switch, having a valve body and a push member. The valve body includes a housing, a main flow passage and a switching mechanism. The housing has at least one support portion formed at a water outlet end that protrudes outwardly. The switching mechanism selectively blocks the main flow passage. The push member is connected to the valve body, and has a water passage portion, at least one suspension portion and a push-abutment portion. The suspension portion is movably connected to the support portion, and the push-abutment portion can drive the switching mechanism to block the main flow passage. As a motion space is formed on the inner side of the suspension portion, the switching mechanism can be driven to operate by pushing the push member in an axial, transverse and/or oblique direction, to switch the arbitrary directional touch switch between closed and open states.

Abstract: The present invention solves problems of cold start, first rater, sparsity and scalability for recommendation. A recommendation system according to the present invention finds association rules through data mining. Then, the recommendation system integrates a rough-set algorithm and a statistical analysis prediction for recommendation. The recommendation is dynamically made from a result of the rough-set algorithm and a result of the statistical analysis prediction by setting a standard deviation as a threshold.
