Abstract: A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

Abstract: Aspects of the subject disclosure may include, for example, a method that includes obtaining, by a processing system including a processor, data regarding customer viewership of a video streaming service. The system defines a time sequence of data items; and defines sampling windows each having a temporal window width. The system constructs a time series for the data by performing an interpolation procedure to generate interpolated data items distributed among the sampling windows. The system transforms the time series to generate a plurality of frequency domain coefficients. The system executes a machine learning algorithm to generate a prediction for future customer viewership, the algorithm has as inputs the frequency domain coefficients. The system also constructs a model for customer behavior using the machine learning algorithm and based on the data and the prediction. Other embodiments are disclosed.
