Abstract: To automate time series forecasting machine learning pipeline generation, a data allocation size of time series data may be determined based on one or more characteristics of a time series data set. The time series data may be allocated for use by candidate machine learning pipelines based on the data allocation size. Features for the time series data may be determined and cached by the candidate machine learning pipelines. Predictions of each of the candidate machine learning pipelines using at least the one or more features may be evaluated. A ranked list of machine learning pipelines may be automatically generated from the candidate machine learning pipelines for time series forecasting based upon evaluating predictions of each of the one or more candidate machine learning pipelines.

Abstract: An angular position sensing system includes a first support with ring-shaped elements disposed thereon and spaced apart from one another in a curvilinear arrangement. Each ring-shaped element includes an electrically-conductive ring and an RFID integrated circuit electrically coupled to its electrically-conductive ring. A second support has an antenna coupled thereto that defines an electrically-conductive path commensurate in size and shape to at least a portion of the electrically-conductive ring. An interrogator transmits a signal to the antenna wherein electric current is generated along the antenna's electrically-conductive path and electromagnetic energy emanates from the antenna. Any ring-shaped element and its RFID integrated circuit energized by the electromagnetic energy generates in response a data transmission for receipt by the interrogator.

Abstract: A psychological stress index measuring system and its analysis method comprise a pulse generator, a transmission-based photo sensor, a signal converter & amplifier, a filter and a processing platform. At first, the transmission-based photo sensor fixed on a user depends on a light transmitting mechanism to detect analog SpO2 (oxyhemoglobin saturation by pulse oximetry) signals. Then, it will be processed and transformed to digital signals and further exported to the processing platform for extraction of PPGA & HBI. Finally, it will pass a median filter, normalization, and development of Psychological Stress Index which is based on the normalized PPGA & HBI as one convenient method to evaluate psychological health.
