Abstract: A machine learning-based method for automatically determining abnormal points of a single indicator includes step 1: randomly selecting M sample points from training data as subsamples, and putting them into a root node of a tree; and step 2: randomly specifying a data dimension for projection, and randomly generating a cutting point p in data of a current node, where the cutting point is generated between a maximum value and a minimum value of the specified dimension in the data of the current node. The present disclosure optimizes conventional data analysis linear model functions and regression model functions, constructs a computer neural network in the algorithm, puts multiple perceptron parameters in a multi-layer network for learning and training, and adopts the principle of principal component analysis, to find out the abnormal data that violates the data correlation.

The apparatus may include a processing device to prevent unintentional activations of one or more touch-sensor buttons caused by a presence of conductive liquid on the one or more touch-sensor buttons.

Abstract: An apparatus and method for discrimination of activation of multiple buttons are described. To discriminate among the activations, a processing device detects multiple activated touch-sensor buttons on a touch-sensor array. The processing device determines a difference value corresponding to a difference between activation signal values for each of the activated touch-sensor buttons and compares the difference value to a difference threshold. If the difference value is above the difference threshold, the processing device determines which of the activated touch-sensor buttons has a greater activation signal value and triggers an operation associated with that touch-sensor button.
