Embodiment 1

[0110] Such as figure 1 As shown, a trend prediction method based on attention mechanism and reinforcement learning includes the following steps:

[0111] S1: Select a futures product and obtain the historical futures market data of the selected product;

[0112] S2: Perform data cleaning on the data;

[0113] S3: Preprocess the data;

[0114] S4: Use pre-processed data to pre-train the feature extraction model;

[0115] S5: Splicing the output of the feature extraction model with the original data for reinforcement learning model training;

[0116] S6: Use the trained reinforcement learning model for decision-making, and derive the decision-making sequence;

[0117] S7: Test on the backtest platform.

[0118] In this example, first select the futures variety, try to choose a variety with a longer establishment time and a larger trading volume, and according to the fractal theory, judge whether the futures is suitable for data enhancement through testing, to a certain ext...

[0127] S7: Test on the backtest platform.

[0128] The specific process of step S1 is:

[0129] S11: Due to the high noise of financial data, compared with other machine learning tasks, training trend prediction models often requires more data to achieve better results. The selected data is minute-level data. Accor...

Embodiment 3

[0140] Such as figure 1 As shown, the present invention provides a trend prediction method based on attention mechanism and reinforcement learning, comprising the following steps:

[0141] S1: Select the futures product according to the fractal theory, and obtain the historical futures market data of the selected product, including the following steps:

[0142] S11: Calculate skewness and kurtosis based on futures historical market data, and screen futures varieties. When 1

[0143] Skewness SKE, also known as the third standard central moment of the probability model, is usually used to describe the symmetry of the data, and the calculation formula is as follows:

Abstract

The invention provides a trend prediction method based on an attention mechanism and reinforcement learning, and the method makes full use of the market information, better captures the market dynamics, enters as much as possible when the futures price is at a low level and has a rising trend, and reduces the probability of decision errors. Firstly, futures varieties are selected, varieties which are long in establishment time and large in trading volume are selected as far as possible, whether futures are suitable for data enhancement or not is judged through testing according to the fractal theory, and the problem that the data volume is small is solved to a certain extent. Then, through data cleaning and a feature extraction model based on an attention mechanism, the ability of the model to extract financial data features is optimized to serve as the input of a final strategy network, finally, a reinforcement learning algorithm is used, continuous action control is introduced, and an intelligent agent with strategy randomness and robustness is obtained; and the intelligent agent can make decisions according to market dynamics.

Description

technical field [0001] The present invention relates to the field of information science, and more specifically, relates to a trend prediction method based on attention mechanism and reinforcement learning. Background technique [0002] Traditional financial investment methods rely to a large extent on requiring investors to have relatively rich financial knowledge, relatively strong ability to resist pressure in the face of market downturns, and decisive decision-making ability. The market is in trouble. Because there are three basic principles in market analysis: 1. Price includes everything. 2. Prices evolve in a trending manner. 3. History repeats itself over and over again. So in recent years, financial innovation and artificial intelligence technology have been successfully combined in various financial applications, including quantitative trading (QT). Although a large amount of research has been dedicated to constructing better QT strategies using deep learning (...
