1. A computer-implemented method for credit risk prediction based on an Long Short-Term Memory (LSTM) model, the method comprising:

  • obtaining behavior data of a target account in a period, wherein the period comprises a plurality of time intervals;

    generating, based on the behavior data of the target account, a sequence of behavior vectors, each behavior vector corresponding to one of the time intervals;

    inputting the generated sequence of behavior vectors into an LSTM encoder in an LSTM model to obtain hidden state vectors each corresponding to one of the time intervals, wherein the LSTM model comprises the LSTM encoder and an LSTM decoder; and

    obtaining a risk score of the target account in a next time interval by inputting the hidden state vectors into the LSTM decoder, wherein the next time interval is next to the last time interval in the plurality of time intervals.
