  • Patent number: 11928009
    Abstract: Aspects of the invention include detecting an error alert from a target computer system. In response to detecting the error alert, performance data is then retrieved from the target computer system. A gated recurrent unit (GRU) neural network is used to generate a prediction of a root cause of the error alert based on the performance data. The weights of a reset gate of the GRU neural network are adjusted based on received feedback of the prediction.
    Type: Grant

  • Patent number: 11086568
    Abstract: According to one embodiment, a memory system includes a volatile memory, a nonvolatile memory and a controller circuit. The controller circuit configured to control the volatile memory and the nonvolatile memory and to perform a write process and a non-volatilization process. The controller circuit is further configured to, during the write process, store write data in the volatile memory, and during the non-volatilization process, upon determining that data size stored in the write buffer being less than unit of writing of the nonvolatile memory, suspend completion of the non-volatilization process and not return a notification of completion of the non-volatilization process.

  • Patent number: 10775739
    Abstract: Disclosed is a coherence-adjustable digital holography system. More particularly, the coherence-adjustable digital holography system includes a light source part for generating low-interference light; a dispersion part for dispersing the generated light, an adjustment part for adjusting coherence by adjusting a spectrum bandwidth of the light which has passed through the dispersion part; and a detection part for detecting a holographic image of a subject from the adjusted light. In accordance with such a configuration, an interference fringe may be easily obtained through coherence adjustment, whereby the accuracy of a detected holographic image may be improved.
