Flight catering quantity prediction method and device, computer equipment and storage medium

The invention relates to a flight catering quantity prediction method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: generating a time sequence of flights according to the length of the time sequence, and counting the number of reservation people in each time period in the time sequence; respectively encoding each time period, and generating a hidden layer vector of each time period by sequentially encoding the residual error of the number of people who reserve the seat in each time period; performing attention mechanism calculation on the code of each time period and the hidden layer vector of each time period to obtain the weight of the seat reservation number of people of each time period; decoding the weight of the number of people who reserve the seat in each time period, and determining a predicted value of the catering amount based on a decoding result; and optimizing the catering quantity prediction model based on an error bet
