摘要： Embodiments of the present invention include systems and methods for improved state space modeling (SSM) comprising two added layers to model the substructure transition dynamics and action duration distribution. In embodiments, the first layer represents a substructure transition model that encodes the sparse and global temporal transition probability. In embodiments, the second layer models the action boundary characteristics by injecting discriminative information into a logistic duration model such that transition boundaries between successive actions can be located more accurately; thus, the second layer exploits discriminative information to discover action boundaries adaptively.

摘要： Phase interpolators are provided, the phase interpolators including: a first phase interpolator having a first output that outputs a first interpolated clock signal based on quadrature clock signals and a first phase interpolator control signal; a second phase interpolator having a second output that outputs a second interpolated clock signal based on the quadrature clock signals and a second phase interpolator control signal that is shifted from the first phase interpolator control signal by half of an integral nonlinearity (INL) period of the first phase interpolator; and a phase combiner that outputs a third interpolated clock signal based on the first interpolated clock signal and the second interpolated clock signal. In some of these embodiments, the phase interpolators further comprise a first amplitude limiter that receives the first interpolated clock signal and outputs a first amplitude-limited interpolated clock signal that is provided to the phase combiner.
