For example, assuming that the target resource information range is 2690-3220 million, performing regression prediction on the target resource information range through a regression prediction model to obtain the predicted resource information of the object to be predicted in the next time period of 3000 million.
In the resource information prediction method, in response to a resource information prediction request for an object to be predicted, resource characteristic information of the object to be predicted in a current time period is acquired; then inputting the resource characteristic information into a pre-trained resource information prediction model to obtain a target resource information range of the object to be predicted in the next time period of the current time period; the pre-trained resource information prediction model is obtained by training according to sample resource characteristic information of a sample object; finally, inputting the resource characteristic information and the target resource information range of the current time period into a pre-trained regression prediction model to obtain the predicted resource information of the object to be predicted in the next time period; the predicted resource information is within the target resource information range. Therefore, when resource information is predicted, a target resource information range of the object to be predicted in the next time period of the current time period is predicted through a pre-trained resource information prediction model, and then predicted resource information of the object to be predicted in the next time period is predicted from the target resource information range through a pre-trained regression prediction model; in the whole process, the pre-trained resource information prediction model and the pre-trained regression prediction model are fully utilized, and the expert rules and the historical experience are not required to be relied on, so that the predicted resource information is more accurate, the improvement of the prediction accuracy of the resource information is facilitated, and the defect that the predicted resource information is not accurate enough due to the expert rules and the historical experience is avoided.
In an embodiment, as shown in fig. 2, in the step S102, the resource feature information is input into a resource information prediction model trained in advance, so as to obtain a target resource information range of the object to be predicted in a time period next to the current time period, which specifically includes the following steps:

The prediction probability is used for measuring the probability that the resource information of the object to be predicted in the next time period of the current time period belongs to a certain preset resource information range.
Specifically, the resource characteristic information of the object to be predicted of the terminal in the current time period is input into a pre-trained resource information prediction model, and the resource characteristic information is subjected to convolution processing and full connection processing through the resource information prediction model to obtain a one-dimensional prediction probability vector; determining the prediction probability that the resource information of the object to be predicted in the next time period of the current time period belongs to each preset resource information range from the one-dimensional prediction probability vector; screening out a preset resource information range with the maximum prediction probability from all preset resource information ranges; and taking the preset resource information range with the maximum prediction probability as a target resource information range of the object to be predicted in the next time period of the current time period.
For example, it is assumed that the prediction probabilities of the resource information range a, the resource information range B, the resource information range C, the resource information range D, and the resource information range E are 0.1, 0.2, 0.4, and 0.1, respectively, and the prediction probability of the resource information range D is the maximum, which indicates that the target resource information range of the object to be predicted in the next time period of the current time period is the resource information range D.
In the embodiment, the resource characteristic information is input into a pre-trained resource information prediction model to obtain the prediction probability of each preset resource information range corresponding to the next time period of the current time period, and the target resource information range of the object to be predicted in the next time period of the current time period is screened out from each preset resource information range according to the prediction probability; therefore, the resource information prediction model trained in advance is comprehensively utilized, the resource information range is favorably and accurately determined, and the prediction accuracy of the resource information is further improved; meanwhile, the whole process does not need manual participation, so that the manpower is reduced, and the prediction efficiency of the resource information is improved.

Wherein, the resource identification refers to currency, such as RMB, USD, euro, etc. The resource information prediction models corresponding to different resource identifications are different.
Specifically, the terminal determines a resource identifier associated with the resource feature information according to the resource identifier identification instruction; screening out a resource information prediction model with the corresponding resource identification matched with the resource identification from pre-trained resource information prediction models to serve as a target resource information prediction model; inputting the resource characteristic information into a target resource information prediction model to obtain a one-dimensional prediction probability vector; determining the prediction probability that the resource information of the object to be predicted in the next time period of the current time period belongs to each preset resource information range from the one-dimensional prediction probability vector; and screening out a preset resource information range with the maximum prediction probability from all the preset resource information ranges, wherein the preset resource information range is used as a target resource information range of the object to be predicted in the next time period of the current time period, such as the actual demand range of position funds of different currencies in the next time period.
In the embodiment, according to the resource identifier associated with the resource characteristic information, a target resource information prediction model meeting the requirement is screened out from pre-trained resource information prediction models, and according to the target resource information prediction model, the prediction probability of each preset resource information range corresponding to the next time period of the current time period is obtained; therefore, by distinguishing the resource information prediction models corresponding to different resource identifications, the accuracy of the predicted resource information range is further improved, the subsequently determined predicted resource information is more accurate, and the prediction accuracy of the resource information is improved.

For example, when the loss value is greater than or equal to the preset threshold, the terminal adjusts the model parameter of the resource information prediction model to be trained according to the loss value, and repeats steps S302 to S304 to train the resource information prediction model after model parameter adjustment again until the loss value obtained through the trained resource information prediction model is less than the preset threshold, and then the trained resource information prediction model is used as the pre-trained resource information prediction model.
Further, after obtaining the target resource information range of the sample object in the next time period of the sample time period, the terminal can predict the target resource information range through a regression prediction model to be trained to obtain the predicted resource information of the sample object in the next time period; and performing joint training on the resource information prediction model to be trained and the regression prediction model to be trained according to the difference between the predicted resource information and the actual resource information of the sample object in the next time period to obtain the trained resource information prediction model and the trained regression prediction model.

In an embodiment, in order to more clearly illustrate the resource information prediction method provided in the embodiments of the present application, the resource information prediction method is specifically described below with a specific embodiment. In one embodiment, the method for planning and predicting the capital position of the overseas bank is characterized in that an artificial intelligent model based on machine learning is established by improving the capital position reporting process, so that the whole process management of position capital reporting, calculation, summarization, limitation, early warning and prediction is realized, manual processing is reduced, the capital position risk of the bank is reduced, the capital use benefit is improved, advance prediction, in-process monitoring and after-event analysis are realized, and decision support is provided for the capital application of the bank. Wherein, fig. 5 provides an overall frame diagram of a fund planning device, which comprises a position account balance summarizing device, a bookkeeping detail calculating device, a fund position reporting device, a position planning summarizing device and a position predicting device. Fig. 6 is a block diagram showing a structure of a fund position submitting apparatus, which includes a UI (User Interface) presentation unit, a workflow unit, a logic calculation unit, and a data storage unit. Fig. 7 provides a block diagram of a position prediction apparatus including a sample selection unit, a target value definition unit, a model design unit, and a result presentation unit. The method specifically comprises the following steps:
step one, linking a bank clearing system according to the currency type related to overseas banks, and acquiring the balance condition of the account in real time. For example, in the morning of each day, the position account balance summarizing device shown in fig. 5 traverses all the related currencies, traverses the balances inquired by all position users in the currencies aiming at each currency, and is linked with the bank clearing system to acquire the balance of the position user in the bank of the T-1 day; firstly, collecting according to single currency, and combining T-1 day exchange rate, converting into general currency such as dollar, port currency, etc. to collect to obtain the use condition of different currency funds and the total fund condition after converting into general currency.
Linking a banking system to acquire bookkeeping information every day; estimating daily fund use condition according to the service classification and the term factors of bookkeeping service types by day; generally, banks have business systems related to financial markets for registering bookkeeping information, and interaction among systems is performed in a file or interface mode to complete acquisition of the bookkeeping information.
And step three, classifying the book details according to the actual operation condition of the bank, such as financial markets, foreign currency derivatives and the like, and carrying out fund exposure summary according to the book-keeping basic elements (interest date, expiration date, current day exchange rate, amount and currency) and according to currency, type maintenance and date. For example, the financial market comprises the types of putting on and leaving the same industry, borrowing the same industry, fund falling, foreign exchange on-demand, foreign exchange forward, financing tools, bond repurchase and the like, each type of element comprises fund, currency, interest date, expiration date and the like, the effective time range of bookkeeping is determined according to the interest date and the expiration date, and then fund exposure required by all bookkeeping can be summarized according to the currency and the bookkeeping types so as to replace partial manual reporting and reimbursement and simplify the reporting process.
And step four, establishing an on-line manual forecasting channel, supporting cross-department information transfer reporting and estimation and alarm of automatic pre-occupation of each reporting fund, and mainly used for reporting funds before bookkeeping information. For example, referring to fig. 6, the ui display unit is used for providing the display of the functions of forecasting, inquiring and examining and approving funds, so as to facilitate the on-line processing of banking staff; the elements of forecasting include beginning of capital, ending time, currency, forecasting business category, etc. The work flow unit is used for carrying out authority division according to the role of the user in a work flow mode, and provides a function of reporting and flowing between cross-department banks. The logic calculation unit is used for automatically judging whether the liquidity risk of the fund exists after the forecast takes effect, and the main idea is to forecast the position fund balance under the current currency by combining the position fund balance summarizing result under the forecast currency obtained in the step one, the bookkeeping detail obtained in the step three and the forecast success record of the current day, namely: clearing account balance, effective bookkeeping details on the current day, forecast funds on the current day, and newly-increased forecast funds = current-day position fund balance; and allowing to enter forecast circulation only when the position fund balance of the day exceeds a preset threshold, and automatically rejecting the report if the position fund balance of the day exceeds the preset threshold. And the data storage and storage unit is used for storing the reporting element information and the circulation information by relying on the database middleware and is used for next-time forecast frame calculation and post analysis.
And step five, calculating the position fund use condition in a future period of time according to the result of the step four and the transverse frame of the date, thereby facilitating the fund reservation or allocation in advance.
And step six, according to the result of the step four, the result of the position balance of the current date is longitudinally calculated according to the service types, the bank service development condition is comprehensively mastered, and support is provided for the operation decision.
Finally, forecasting the position fund, calculating the using condition of the fund through the previous steps, mainly aiming at the problems that the capacity of resisting unexpected risks is low on the premise that banks normally operate, particularly, the manual forecasting part is relatively dependent on the experience of people, and the overseas fund environment is complex, the manual judgment is often greatly deteriorated, and factors such as season rate change, history, politics, period, natural disasters and the like need to be considered, so that the method based on LightGBM modeling is also provided by referring to fig. 7, and the position fund is forecasted according to time-related business data. The method specifically comprises the following steps:
a sample selection unit: besides the time, currency and position fund usage amount, the model supplements external data such as exchange rate, gold ETF fluctuation index, dollar index, dojones industry index, policy uncertainty index and Chinese certificate index, meanwhile, the external data is subjected to time period sliding window derivation processing, and finally 70 characteristic fields are selected, wherein the date is used as a sample unique identification field.
A target value definition unit: for the prediction target of the cross-border fund position amount range, five quantile intervals are divided, wherein the five quantile intervals are respectively more than 0-2130 (million), 2130-2690 (million), 2690-3220 (million), 3220-4110 (million) and 4110 (million).
A model design unit: the LightGBM model can obtain better effect than other models, and is favorable for playing better model training effect. In order to guarantee the maximum possible data volume for model training under limited data, a leave-one-out method is used for modeling during training, namely a training data set (assuming that n samples are total) is divided into a training set (n-1 samples) and a testing set (1 sample), and the training is carried out for n times. The model design firstly carries out range prediction on the position historical data, combines the model effect, and carries out regression prediction again on the categories with higher classification prediction accuracy.
A result display unit: the results are shown in Table 1. Referring to table 1, it can be seen that the prediction accuracy exceeds 80% for the fund of which the model prediction exceeds 4000 ten thousand, and the effect is good.
