We introduce Eigen Evolution Pooling, an efficient method to aggregate a sequence of feature vectors. Eigen evolution pooling is designed to produce compact feature representations for a sequence of feature vectors, while maximally preserving as much information about the sequence as possible, especially the temporal evolution of the features over time. Eigen evolution pooling is a general pool...

Rotors with high gyroscopic effects and low resonance frequencies caused by the blade wheel (blade frequencies) can lead to stabilization problems in the application field of turbomolecular pumps. If such a rotor is stabilized by active magnetic bearings, the control structure could be destabilized by the splitting up of the rigid body eigen-frequencies caused by the gyroscopic effect. The cont...

The mechanisms of interdecadal changes of El NifioSouthern Oscillation (ENSO) modes are examined through an eigen analysis of a simple coupled ocean-atmosphere model. It is shown that the observed interdecadal climate shift can effectively modify the strength of two major coupled feedbacks for the ENSO mode, namely, the zonal advection and thermocline feedbacks. These modifications lead to quan...

In this paper, we propose a new adaptive algorithm for generalized eigen-decomposition problems which plays very important roles in signal processing for wireless communication. We apply the algorithm to solve the problem of co-channel interference cancellation in Orthogonal Frequency Division Multiplexing (OFDM) communication system with virtual carriers. Finally, the simulations are performed...

Temperature variation degrades the performance of fiber-optic gyroscopes. In terms a noise mechanism, we report that thermal phase contributes to dominant effect temperature in large gyroscopes when conventional Shupe is basically suppressed. High-order frequency modulation introduced reduce corresponding variation. A time-varying experiment has been carried out for verification. Compared with ...

Deformations in handwritten characters have classdependent tendencies. For example, characters of class “A” are often deformed by global slant transformation and never deformed to be similar to “R”. In this paper, the extraction and the utilization of such tendencies called eigen-deformations are investigated for better performance of elastic matching based recognition systems. The eigen-deform...
