Abstract: An approach for a computer to evaluate a predictive model includes identifying features of training samples in a set of training samples. The approach selects evaluation metrics from a set of evaluation metrics as available metrics using identified features and includes determining recommended metrics using the predictive model, the available metrics, and a predetermined set of user-preferred metrics. The approach applies the predictive model created using the set of training samples to a set of test samples to calculate values of the available metrics. The approach evaluates the predictive model by using the available metrics and the values of the available metrics to evaluate the predictive model by evaluating the predictive model using the recommended metrics and the values of the recommended metrics.

Abstract: The present disclosure discloses a method and an apparatus for building a missing part of a movement path of an object. One or more frequent points is determined, wherein each of the one or more frequent points is a point on a historical movement path having a number of occurrences greater than a first threshold. A credibility of one or more path segments in determined. A first path segment of the one or more path segments is selected, wherein the credibility of the first path segment is greater than a second threshold. A missing part of a movement path of an object is built using the first path segment.

Abstract: A method and an apparatus for determining a location of a mobile device. The location of a mobile device is determined accurately according to information which includes call data records of the mobile device. By employing a partial ellipse integral model, two physical world factors are taken into consideration in reducing the location uncertainty in call data records. The factors include: spatiotemporal constraints of the device's movement in the physical world and the telecommunication cell area's geometry information, which increase the accuracy of determining the location of a mobile device.
