Abstract: A control method and apparatus for displaying multimedia content, an electronic device, and a medium. The method includes: displaying a first-type multimedia content on a first content display layer of a first-type multimedia content display interface, the first-type multimedia content display interface including: a first user interaction layer and the first content display layer, the first user interaction layer being superimposed and displayed on the first content display layer; and receiving a first swiping operation inputted by a user on the user interaction layer, and exiting the first-type multimedia content display interface. That is, a swiping operation triggers to exit the first-type multimedia content display interface, as the swiping operation is significantly different from a click operation, the user is provided with a multimedia content display control method that is more consistent with the user's operation habit, improving the user experience.

Abstract: An intelligent monitoring method and apparatus for abnormal working conditions in a heavy metal wastewater treatment process based on transfer learning and a storage medium are provided. During an intelligent monitoring, the abnormal working conditions can be automatically and intelligently recognized by fusing data in the treatment process of the heavy metal wastewater different in source; specifically, a normal sample YSD in the treatment process of the heavy metal wastewater with fixed sources and a small number of normal samples YTD in the treatment process of the heavy metal wastewater with unknown sources are utilized; and first, a data representation dictionary DSD of YSD is obtained through learning on YSD, and then considering different distribution of YSD and YTD, a transfer learning method is adopted to fuse characters of YTD into a dictionary learning process to obtain a dictionary DTD with higher generalization ability.
