Abstract: This disclosure provides methods and apparatuses for providing interpretability for multivariate time-series data anomaly detection. The multivariate time-series data anomaly detection is performed, through a multivariate time-series data anomaly detection model, for a multivariate time-series data formed by multiple time-series data. An anomaly detection result indicating at least an anomaly period is obtained from the model. An anomaly period correlation metric of the multiple time-series data in the anomaly period is determined. A trace-back period correlation metric of the multiple time-series data in a trace-back period before the anomaly period is determined. At least one time-series data pair having abnormal correlation in the anomaly period is identified from the multiple time-series data, based on a difference between the anomaly period correlation metric and the trace-back period correlation metric.

Abstract: A non-volatile memory system separately performs a memory operation for multiple sub-blocks of a block in order from previously determined slowest sub-block of the block to a previously determined faster sub-block of the block. As a slower sub-block is more likely to fail, this order of is more likely to identify a failure earlier in the process thereby saving time and reducing potential for a disturb. In some embodiments, the proposed order of operation can be used in conjunction with a programming process that concurrently programs blocks in multiple planes using completion of programming of a fastest plane to a data state as a trigger to test for program failure of other planes to the data state.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: A method and a device for testing linear deviation in high-speed frequency-modulated (FM) signals. The to-be-tested high-speed FM signal is modulated onto the optical domain by a high-speed electro-optic modulator. The optical signal is then split into two paths with differential delays using a high-speed tunable optical delay line, and mixed in the optical domain for detection. After filtering out the down-converted signal and low-frequency signal generated by the direct digital synthesizer (DDS), the phase detection is performed. The high-speed analog-to-digital converter (ADC) is used for data acquisition, reception, and analysis. By changing the delay of the high-speed tunable optical delay line and the frequency of the low-frequency signal generated by DDS, and conducting multiple measurements, polynomial fitting is applied to the sampled data to obtain the linear deviation of the high-speed FM signal under test.
