A prototype of fully flexible intelligent contact lens, which are shown in the impressive action movie series of “MISSION: IMPOSSIBLE”, has become the Possible Mission in this work. Hereon, the system adopts analog-to-information processing method to build a specific Multi-Layer Perceptron network for image classification tasks with flexible devices and circuits, where the information is extracted...
Nonnegative Matrix Factorization (NMF) factorizes a nonnegative matrix into product of two positive matrixes, which is widely used in hyperspectral unmixing. However, the convergence speed of NMF is comparatively slower, and a large number of local minimum will be existed when it is directly adopted in the factorization of hyperspectral image mixed pixels. A modified hyperspectral unmixing method...
As a powerful tool in machine learning, Support Vector Machine(SVM) also suffers from expensive computational cost in the training phase due to the large number of original training samples. To overcome this problem, this paper presents a new method based on a two steps of sample reduction to reduce training samples. This algorithm includes cluster detection by Fuzzy C-Means Clustering (FCM) Cluster...
An approach is proposed to discover closed frequent itemsets with a simple linear list structure called the Frequent Pattern List(FPL) in transaction database. The approach selects representation patterns from candidate itemsets to reduce combinational space of frequent patterns. By performing two operations, signature vertex conjunction and vertex counting, it simplify the process of closed itemsets...
