Filed:

Nov 21, 2001

Appl. No.:

09/992050

Inventors:

Dong Lin - Fremont CA 94539

International Classification:

G02B 628

US Classification:

385 11, 385 24, 385 36, 359495, 359496, 359497

Abstract:

A micro-optic polarization beam multiplexing system has collimating means for introducing a first pair of polarization-perpendicular input beams, collimating means for introducing a second pair of polarization-perpendicular input beams, a polarization beam combiner for combining the first pair and the second pair of input beams into a first combined light beam with wavelength and a second combined light beam with wavelength , and a filter for multiplexing the first combined light beam and the second combined light beam into an output beam with wavelengths and. The micro-optic system can also be used inversely for de-multiplexing an input beam with wavelength and wavelength into a first de-multiplexed light beam with wavelength and a de-multiplexed light beam with wavelength , and then splitting them into two pairs of polarization-perpendicular beams.

Abstract:

A system and method for transparent data replication of one or more data containers over migrating virtual servers (vfilers) operating on physical storage systems is provided. A mirroring (or other replication) procedure associated with a vfiler generates an entry in a mirror table maintained by one or more appropriate mirroring applications executing on the physical storage systems. The mirror table identifies source and destination “owners” of a replicated data container by vfiler instead of only by physical storage system. Thus, when a vfiler is migrated from a source physical storage system (“source”) to a destination physical storage system (“destination”), the mirroring application may continue to perform mirroring operations on the data containers at a per vfiler level to thereby improve the utility of migration of the vfiler among the storage systems.

Abstract:

Aspects of the present disclosure are directed to novel activation functions which enable improved reproducibility and accuracy tradeoffs in neural networks. In particular, the present disclosure provides a family of activation functions that, on one hand, are smooth with continuous gradient and optionally monotonic but, on the other hand, also mimic the mathematical behavior of a Rectified Linear Unit (ReLU). As examples, the activation functions described herein include a smooth rectified linear unit function and also a leaky version of such function. In various implementations, the proposed functions can provide both a complete stop region and a constant positive gradient (e.g., that can be 1) pass region like a ReLU, thereby matching accuracy performance of a ReLU. Additional implementations include a leaky version and/or functions that feature different constant gradients in the pass region.
