Abstract: Systems, methods, and software can be used to determine similarity samples. In some aspects, a method includes: obtaining one or more feature vectors of a sample, each of the one or more feature vectors corresponds to a user-selected feature group; and selecting a set of similarity samples based on the one or more feature vectors, wherein the selecting the set of similarity samples based on the one or more feature vectors comprises: for each of the one or more feature vectors, selecting a corresponding set of feature similarity samples based on the corresponding feature vector; and combining the corresponding selected set of feature similarity samples for each of the one or more feature vectors to generate the set of similarity samples.

Abstract: Systems, methods, and software can be used to determine similarity samples. In some aspects, a method includes: obtaining a first feature vector of a sample; processing the first feature vector through a plurality of dimensionality reduction processes, wherein each of the plurality of dimensionality reduction processes generates a respective second feature vector, each of the second feature vectors has a smaller dimension than a dimension of the first feature vector; for each of the second feature vectors, determining an intermediate set of similarity samples; and aggregating the intermediate sets of similarity samples to generate an output set of similarity samples.

Abstract: Systems, methods, and software can be used to determine whether a software code is unwanted. In some aspects, a method includes: obtaining, by an electronic device, a set of software features of a software code; obtaining, by the electronic device, a set of user features of a user of the electronic device; and determining, by the electronic device, a classification score of the software code based on the set of software features and the set of the user features, wherein the classification score indicates whether the software code is potentially unwanted for the user.

In some aspects, a method includes: receiving an alert, wherein the alert comprises activity information and user information; obtaining a set of activity features based on the activity information; obtaining a set of user features based on the user information; and determining a score of the alert based on the set of activity features and the set of user features.

Abstract: An electronics system has a board with a thermal interface having an exposed surface. A thermoelectric device is placed against the thermal interface to heat the board. Heat transfers through the board from a first region where the thermal interface is located to a second region where an electronics device is mounted. The electronics device has a temperature sensor that detects the temperature of the electronics device. The temperature of the electronics device is used to calibrate an accelerometer and a gyroscope in the electronics device. Calibration data includes a temperature and a corresponding acceleration offset and a corresponding angle offset. A field computer simultaneously senses a temperature, an acceleration and an angle from the temperature sensor, accelerometer and gyroscope and adjusts the measured data with the offset data at the same temperature. The field computer provides corrected data to a controlled system.
