Abstract: Described is a system for analyzing time series data. A sequence of symbols is generated from a set of time series input data related to a moving vehicle using automatic segmentation. A grammar is extracted from the sequence of symbols, and the grammar is a subset of a probabilistic context-free grammar (PCFG).

Abstract: A target account detection method and apparatus, an electronic device, and a storage medium. The method includes: determining an active behavior timing feature of a target account to be detected according to active behavior data of the target account; determining an account feature of the target account according to account data of the target account; predicting a first probability that the target account is of a target type; and determining, in response to the first probability being greater than a target probability threshold, that the target account is of the target type. Detection is performed in the dimension of timing, so that the impact of an account of a target type pretending to be a normal account on detection can be reduced, and more accounts of the target type can be detected, thereby enlarging the identification coverage.

The iterative process includes receiving sensor data for a current state of the moving target. The process also includes applying a filter engine to the sensor data and a measure of error of a previous prediction of the current state of the target to produce a first estimate for an upcoming state and a first measure of error thereof. The process also includes receiving from at least one second tracking system, at least one second estimate for the upcoming state and second measure of error thereof. The process further includes defining a consensus estimate for the upcoming state and a consensus measure of error thereof using the first estimate and the at least one second estimate and the first and second measure of error thereof.

Abstract: Described is a system for biometric based security. The system applies a reusable fuzzy vault (RFV) process to protect secret information. The RFV process comprises a locking algorithm and an unlocking algorithm. The locking algorithm takes as input a fuzzy string m generated from readings of biometrics and secret information sk to be protected, The locking algorithm outputs a public string vault and a hash value h of sk. The unlocking algorithm takes as input a public string vault and a fuzzy string m?, and outputs a string sk? if fuzzy string m? is sufficiently close to fuzzy string m. The unlocking algorithm further computes a hash value h? of sk? and compares it with h. The system allows access to the secret information sk when h? is equivalent to h.

Abstract: An apparatus is provided for tracking a target moving between states using an iterative process. The apparatus receives sensor data for a current state i, and applies a cubature information filter and an H-infinity filter thereto to respectively produce an estimate for the upcoming state i+1 and a measure of error thereof, and adjust the measure of error. The apparatus then defines a consensus estimate of the upcoming state i+1 and a consensus adjusted measure of error thereof from the estimate and adjusted measure of error, and a second estimate and second adjusted measure of error that is received from at least one second apparatus tracking the target. The apparatus then applies a cubature information filter to the consensus estimate of the upcoming state i+1 and the consensus adjusted measure of error to predict the upcoming state i+1.

Abstract: Pin layouts for HSIO require a large number of pins due to isolation requirements. Differential signaling can be used in high speed transmission and reception. A single lane for operation at 6 to 8 Gbps speed typically a total of six to eight pins. At higher speeds, conventional technique to meet isolation requirements is to increase the number of ground pins per lane. With many lanes, the number of pins can become cumbersome. To address such issues, it is proposed to provide pin patterns that leverage differential cancellation to enhance signal isolation so that operation speed can increase while also reducing the number of pins so that the number of pins of a package is less cumbersome.
