如圖1所示，是本說明書一個實施例的外匯交易量預測方法流程圖。所述方法可包括：
步驟102：分別根據各個業務日的外匯交易量預測值和對應業務日的外匯交易量真實值計算外匯交易量的變化趨勢，並根據所述變化趨勢對未來時間段內的外匯交易量進行預測，其中，各個業務日的外匯交易量預測值分別根據以下方式獲取：
步驟104：分別將當前預測時間節點之前的歷史外匯交易量輸入預先訓練的多個預測模型，獲取各個預測模型對應的當前第一預測結果；
步驟106：根據各個當前第一預測結果計算所述當前預測時間節點之後第N個業務日的外匯交易量預測值；N為預設的正整數。
在上述實施例中，業務日即業務量的一個統計週期，其可以與自然日(0：00至23：59)相同，也可以由業務系統預先設定，例如，可以設定為某個自然日的15：00至次日的14：59，或者設定為其他時間段。
在步驟102中，可以獲取多個業務日的外匯交易量預測值和外匯交易量真實值，例如，可以獲取(N1，N2，……，NT)共T個業務日的外匯交易量預測值和外匯交易量真實值，預測值和真實值分別設為(v1，v2，……，vT)和(V1，V2，……，VT)。在計算外匯交易量的變化趨勢時，可以計算對應業務日的真實值與預測值的比值，將各個業務日對應的比值作為外匯交易量的變化趨勢。即，外匯交易量的變化趨勢為(V1/ v1，V2/ v2，……，VT/ vT)。
根據所述變化趨勢對未來時間段內的外匯交易量進行預測，可以根據第i個業務日之前的多個業務日的變化趨勢對第i個業務日的外匯交易量進行預測，根據第i+1個業務日之前的多個業務日的變化趨勢對第i+1個業務日的外匯交易量進行預測，以此類推。其中，每個業務日的外匯交易量預測值vi(1≤i≤T)可透過執行步驟104和步驟106來獲取。
在步驟104中，當前預測時間節點可以根據實際需要設定，一般來說，可以採用當前預測時間節點以前的外匯交易量來預測當前預測時間節點之後第N天的外匯交易量。假設當前預測時間節點為T，待預測的外匯交易量為當前預測時間節點之後第N天的外匯交易量，這種預測方式可稱為T+N預測。
重複執行步驟104和步驟106，可以根據當前預測時間節點T之前的外匯交易量來獲取當前預測時間節點T的T+N預測結果，根據當前預測時間節點T+1之前的外匯交易量來獲取當前預測時間節點T+1的T+N預測結果，以此類推。
用於預測的外匯交易量可以按照時間順序生成時間序列資料。這裡的外匯交易量可以是正向交易量，也可以是逆向交易量。在消費場景中，用戶的購買付款行為與用戶退款行為帶來的是相反的資金流動，在資金結算時，對於商家視角，用戶付款行為為一種正向交易，用戶退款行為為一種逆向交易，因此，正向交易量即用戶向商家付款的總量，逆向交易量即為用戶從商家退款的總量。
還可以獲取各個業務日的業務日日期屬性和/或業務日促銷屬性，以用於對特定業務日的預測結果的修正。其中，業務日日期屬性即業務日對應的日期是否月初、月末、月中、工作日、非工作日或者節假日等屬性。業務日促銷屬性即業務日是否存在促銷活動以及促銷活動的活動等級，其中，活動等級由促銷活動的折扣力度、覆蓋商家範圍、預期交易量等因素來決定。一個實施例的時間序列資料如圖2所示。
在一個實施例中，獲取各個預測模型對應的當前第一預測結果時，可以將當前預測時間節點之前的歷史外匯交易量輸入預先訓練的第一預測模型，獲取第一預測模型對應的第一預測結果；將距當前預測時間節點最近N個業務日的歷史外匯交易量輸入預先訓練的第二預測模型，獲取第二預測模型對應的第一預測結果；以及將當前預測時間節點的歷史同期N個業務日的歷史外匯交易量輸入預先訓練的第三預測模型，獲取第三預測模型對應的第一預測結果。
第一訓練模型根據歷史全量資料來獲取第一預測結果，第二訓練模型根據最近N個業務日的資料來獲取第一預測結果，第三訓練模型根據歷史同期資料來獲取預測結果。三種模型分別從不同的角度來獲取預測結果，最後將各個模型的預測結果綜合起來得到外匯交易量預測值，能夠減少各個模型自身的預測偏差，獲取較為平穩的預測結果。
其中，所述第一預測模型可以是ARIMA (Autoregressive Integrated Moving Average Model，自回歸積分滑動平均模型)，所述第二預測模型可以是均值估計模型，所述第三預測模型可以是環比趨勢估計模型。ARIMA模型能感知資料週期趨勢、增長趨勢、季節趨勢；均值估計模型是就按近期的資料的均值，獲得的預測值，偏重於對近期穩定趨勢的模仿；環比趨勢估計模型參考歷史同期走勢，用歷史同期的趨勢預測當期的趨勢，偏重於對歷史同期的模仿。當然，在實際應用中所採用的預測模型的種類和數量均不限於上述實施例，可採用其他數量的多種能夠獲得穩定性趨勢的預測模型來替代上述模型。一個實施例的外匯交易量預測總體原理圖如圖3所示。
對於ARIMA模型，可以將歷史全量資料直接輸入該模型，以獲取第一預測結果。對於均值估計模型，可以對距當前預測時間節點最近N個業務日的歷史外匯交易量求平均，將均值作為第一預測結果。對於環比趨勢估計模型，可以當前預測時間節點的歷史同期(記作day1)的前N天的歷史值以及day1後M天的歷史值總和。用當前預測時間節點的前N天的歷史值去除以day1的前N天的歷史值，得到環比比值r，接著用這個環比比值r去乘以day1後M天的歷史值總和，得到最終的預測值。M的取值為正整數，可選地，M的值為1。
在步驟106中，可以將各個當前第一預測結果的加權平均值作為所述當前預測時間節點之後第N個業務日的外匯交易量預測值。各個第一預測結果的權值可以是常態化權值，即權值之和為1。
在一個實施例中，所述方法還包括：根據特定業務日的外匯交易量預測值計算所述特定業務日的影響因子；根據所述影響因子對未來時間段中特定業務日的外匯交易量預測值進行修正。
其中，特定業務日是可能存在對外匯交易量具有較大影響的事件的業務日。例如，可以是月初業務日、月末業務日、節假日，或者雙十一、雙十二等舉行大促銷活動的業務日。透過對特定業務日的外匯交易量預測值進行修正，能夠提高預測準確度。
具體地，可以將所述特定業務日的外匯交易量預測值與所述特定業務日的外匯交易量的真實值的比值作為所述影響因子，並以此影響因子來對未來時間段中特定業務日的外匯交易量預測值進行修正。
其中，特定業務日的外匯交易量預測值的獲取方式可以採用與步驟104類似的方式。即，分別將特定業務日的外匯交易量輸入所述多個預測模型，獲取各個預測模型對應的第二預測結果；根據各個第二預測結果計算所述特定業務日的外匯交易量預測值。可選地，這裡採用的多個預測模型可以與步驟104採用的各個預測模型相同，每種模型的預測方式也可以與步驟104中各個預測模型的預測方式相同。
進一步地，在獲取各個預測模型對應的第二預測結果之後，可以將各個第二預測結果的加權平均值作為所述特定業務日的外匯交易量預測值。
本說明書實施例對於沒有更多的資訊的時間序列，只知道特定業務日的日期屬性時，將特定業務日中的T+N的N天資料預測分為兩部分，一部分是序列的穩定趨勢，一部分是由於特定業務日帶來的影響因素與趨勢，最後將兩部分趨勢相融合，以得到未來時間段的外匯交易量預測值，提高了預測結果的準確度。
以上實施例中的各種技術特徵可以任意進行組合，只要特徵之間的組合不存在衝突或矛盾，但是限於篇幅，未進行一一描述，因此上述實施方式中的各種技術特徵的任意進行組合也屬本說明書公開的範圍。

As shown in FIG. 1, it is a flowchart of a method for predicting foreign exchange transaction volume according to an embodiment of the present specification. The method may include:
Step 102: Calculate the change trend of the foreign exchange transaction volume based on the predicted value of the foreign exchange transaction volume of each business day and the real value of the foreign exchange transaction volume of the corresponding business day, and predict the foreign exchange transaction volume in the future time period according to the change trend, Among them, the predicted value of the foreign exchange transaction volume for each business day is obtained according to the following methods:
Step 104: Input the historical foreign exchange transaction volume before the current prediction time node into multiple pre-trained prediction models to obtain the current first prediction result corresponding to each prediction model;
Step 106: Calculate the predicted value of the foreign exchange transaction volume at the Nth business day after the current prediction time node according to each current first prediction result; N is a preset positive integer.
In the above embodiment, the business day is a statistical period of the business volume, which can be the same as the natural day (0:00 to 23:59), or can be preset by the business system. For example, it can be set to a natural day. 15:00 to 14:59 the next day, or set to another time period.
In step 102, the predicted value of the foreign exchange trading volume and the real value of the foreign exchange trading volume for multiple business days can be obtained, for example, the predicted value of the foreign exchange trading volume for a total of T business days (N1, N2, ..., NT) and The real value, predicted value and real value of foreign exchange trading volume are set to (v1, v2, ..., vT) and (V1, V2, ..., VT). When calculating the change trend of foreign exchange trading volume, you can calculate the ratio of the real value and the predicted value of the corresponding business day, and use the ratio of each business day as the change trend of foreign exchange trading volume. That is, the change trend of foreign exchange trading volume is (V1/ v1, V2/ v2, ..., VT/ vT).
The foreign exchange transaction volume in the future time period is predicted according to the change trend, and the foreign exchange transaction volume on the i-th business day can be predicted according to the change trend of multiple business days before the i-th business day, according to the i+ The change trend of multiple business days before one business day predicts the foreign exchange transaction volume on the i+1th business day, and so on. Among them, the predicted value of the foreign exchange transaction volume vi (1≤i≤T) for each business day can be obtained by executing steps 104 and 106.
In step 104, the current prediction time node can be set according to actual needs. Generally speaking, the foreign exchange transaction volume before the current prediction time node can be used to predict the foreign exchange transaction volume on the Nth day after the current prediction time node. Assuming that the current prediction time node is T, and the foreign exchange transaction volume to be predicted is the foreign exchange transaction volume on the Nth day after the current prediction time node, this prediction method may be called T+N prediction.
Repeat steps 104 and 106 to obtain the T+N prediction result of the current prediction time node T according to the foreign exchange transaction volume before the current prediction time node T, and the current foreign exchange transaction volume before the current prediction time node T+1 Predict the T+N prediction result of time node T+1, and so on.
The foreign exchange transaction volume used for forecasting can generate time series data in chronological order. The foreign exchange trading volume here can be a forward trading volume or a reverse trading volume. In the consumption scenario, the user's purchase and payment behavior and the user's refund behavior bring opposite capital flows. When the funds are settled, for the merchant's perspective, the user's payment behavior is a forward transaction, and the user's refund behavior is a reverse transaction Therefore, the forward transaction volume is the total amount the user pays to the merchant, and the reverse transaction volume is the total amount the user refunds from the merchant.
The business day date attribute and/or business day promotion attribute of each business day can also be obtained for the correction of the prediction result of a specific business day. Among them, the business day date attribute refers to whether the date corresponding to the business day is at the beginning of the month, the end of the month, the middle of the month, the working day, the non-working day or the holiday. The business day promotion attribute refers to whether there is a promotion activity on the business day and the activity level of the promotion activity, where the activity level is determined by factors such as the discount strength of the promotion activity, the coverage of the merchant, and the expected transaction volume. The time series data of one embodiment is shown in FIG. 2.
In one embodiment, when obtaining the current first prediction result corresponding to each prediction model, the historical foreign exchange transaction volume before the current prediction time node may be input into the pre-trained first prediction model to obtain the first prediction corresponding to the first prediction model Results; the historical foreign exchange transaction volume of the N business days closest to the current forecast time node is input into the pre-trained second forecast model to obtain the first forecast result corresponding to the second forecast model; and the historical period of the current forecast time node is N The historical foreign exchange transaction volume on the business day is input into the pre-trained third prediction model to obtain the first prediction result corresponding to the third prediction model.
The first training model obtains the first prediction result based on the historical full amount of data, the second training model obtains the first prediction result based on the data of the last N business days, and the third training model obtains the prediction result based on historical synchronization data. The three models obtain the prediction results from different angles. Finally, the prediction results of each model are combined to obtain the predicted value of the foreign exchange transaction volume, which can reduce the prediction deviation of each model itself and obtain a relatively stable prediction result.
Wherein, the first prediction model may be an ARIMA (Autoregressive Integrated Moving Average Model, Autoregressive Integrated Moving Average Model), the second prediction model may be an average estimation model, and the third prediction model may be a chain trend estimation model . The ARIMA model can perceive the periodic trend, growth trend, and seasonal trend of the data; the mean estimation model is based on the average value of the recent data, and the predicted value is focused on the imitation of the recent stable trend; the chain trend estimation model refers to the historical trend during the same period. Historical trends over the same period predict current trends, with a focus on imitation of historical periods. Of course, the types and numbers of prediction models used in practical applications are not limited to the above embodiments, and other numbers of various prediction models that can obtain stability trends can be used instead of the above models. The overall schematic diagram of the foreign exchange transaction volume prediction of one embodiment is shown in FIG. 3.
For the ARIMA model, all historical data can be directly input into the model to obtain the first prediction result. For the mean value estimation model, the historical foreign exchange transaction volume of the N business days closest to the current prediction time node can be averaged, and the average value is used as the first prediction result. For the chain-on-trend estimation model, the sum of the historical value of the previous N days and the historical value of M days after day1 can be predicted at the current time period (denoted as day1) of the current node. Divide the historical value of the previous N days of the current prediction time node by the historical value of the previous N days of day1 to obtain the chain ratio r, and then use this chain ratio r to multiply the sum of the historical values of M days after day1 to obtain the final prediction value. The value of M is a positive integer. Optionally, the value of M is 1.
In step 106, the weighted average of each current first prediction result may be used as the predicted value of the foreign exchange transaction volume at the Nth business day after the current prediction time node. The weight of each first prediction result may be a normalized weight, that is, the sum of the weights is 1.
In one embodiment, the method further includes: calculating the impact factor of the specific business day according to the predicted value of the foreign exchange trading volume of the specific business day; and predicting the foreign exchange trading volume of the specific business day in the future time period according to the impact factor The value is corrected.
Among them, a specific business day is a business day where there may be events that have a greater impact on foreign exchange transactions. For example, it may be a business day at the beginning of the month, a business day at the end of the month, a holiday, or a business day where a big promotional event is held, such as Double Eleven and Double Twelve. By correcting the predicted value of foreign exchange transactions on a specific business day, the accuracy of the forecast can be improved.
Specifically, the ratio of the predicted value of the foreign exchange transaction volume of the specific business day to the true value of the foreign exchange transaction volume of the specific business day can be used as the impact factor, and the impact factor can be used to determine the specific business in the future time period. The daily foreign exchange trading volume forecast value is revised.
Among them, a method similar to step 104 may be used to obtain the predicted value of the foreign exchange transaction volume on a specific business day. That is, the foreign exchange transaction volume on a specific business day is input into the plurality of prediction models respectively to obtain the second prediction results corresponding to each prediction model; and the predicted value of the foreign exchange transaction volume on the specific business day is calculated according to each second prediction result. Optionally, the multiple prediction models used here may be the same as the prediction models used in step 104, and the prediction method of each model may also be the same as the prediction methods of the prediction models in step 104.
Further, after obtaining the second prediction results corresponding to each prediction model, the weighted average of each second prediction result may be used as the predicted value of the foreign exchange transaction volume on the specific business day.
In the embodiment of the present specification, for a time series with no more information and only knowing the date attribute of a specific business day, the T+N N-day data forecast in a specific business day is divided into two parts, one part is the stable trend of the series, One part is due to the influencing factors and trends brought by a specific business day. Finally, the two parts of the trend are merged to obtain the predicted value of foreign exchange trading volume in the future time period, which improves the accuracy of the prediction results.
The various technical features in the above embodiments can be combined arbitrarily, as long as there is no conflict or contradiction between the combination of features, but the space is limited and the description is not carried out one by one. Therefore, any combination of various technical features in the above embodiments also belongs to The scope of this specification.
