Abstract: A multiplexed display panel and device and a driving method for the multiplexed display panel are provided. At the moment when a switching switch is turned on, a potential of a fanout line corresponding to a data line connected to sub-pixels, into which an data signal is input, is adjusted to the same level as a potential of the data line as much as possible, and a potential difference between each fanout line and the corresponding data line is relatively small at the moment when the switching switch is turned on, so that an instantaneous current at this moment is greatly reduced without causing relatively large jump of the potential of the data line, a common electrode and back-plated indium tin oxide (ITO) greatly fluctuate, and then the surface noise generated by the display panel is turned on is greatly reduced.

Abstract: A data feature processing method and a data feature processing apparatus are provided, which perform the following operations: sorting a plurality of groups of business data to obtain a business data sorting sequence, and determining a cross-time validation set and modeling sample data to establish a recognition model by using a preset classifier; calculating feature importance values of data features in the business data based on the recognition model and a gain indicator of the recognition model, and calculating a correlation matrix by taking the modeling sample data as a benchmark; determining to-be-selected model features based on the correlation matrix; and importing the to-be-selected model features into the preset classifier in batches to determine model benchmark performance data. In this way, a highly-correlated feature can be deleted based on an order of the feature importance values. This can reduce operation time and memory demands in a model establishment process.
