Embodiment 1

[0022] Embodiment 1, a kind of automatic market analysis method based on multimodal learning, first trains the learning device, and then utilizes the trained learning device to predict the market in actual use; the method for the training of the learning device is: first Collect information of different modalities such as market data or market description text information and mark the information; then use the multi-instance generation method of market data features and text features to convert the underlying features into the form of multi-instance packages; finally adopt the Using a variety of multi-instance multi-label learning methods of different modalities to fuse data and perform multi-label learning.

Embodiment 2

[0023] Embodiment 2, in the automatic market analysis method based on multimodal learning described in Embodiment 1: the specific steps of the training of the learning device are as follows:

[0024] Step 100, collect various modal information of the market, and manually mark the collected objects;

[0025] Step 101, convert the collected underlying features of market information into a multi-instance package representation through the multi-instance generation method: {(x, t), y}, where the media object is marked as x, and the corresponding other modal information is recorded as t , manually marked as y;

[0026] Step 102, use the training model M to train the collected data to obtain relevant model parameters: marker generation sub-model parameters α, β y ;Market direct market eigenmode information generation sub-model parameter β c ;Other modal information generation sub-model parameters β t And the multimodal input latent variable controls the model parameter η.

Embodiment 3

[0032] Embodiment 3, in the automatic market analysis method based on multimodal learning described in embodiment 1 and embodiment 2: the specific steps of the training of the learning device are as follows: the steps of using the learning device are as follows:

[0033] Step 200, collect test market data characteristics (if there are other modal data, also collect);

[0034] Step 201, transform the underlying characteristics of the market conditions into the representation form {(x)} or {(x, t)} of the multi-instance package through the multi-instance generation method;

[0035] Step 202, use the training model M to process the new market feature I, and output the prediction mark y.

[0036] The generative probability model modeling method of the training model M is:

[0037] (1) (marker-theme submodel part) Let the market quotations be generated by the theme model, where the mark y is determined by the parameter α through the Latent Dirichlet Allocation (LDA) submodel and t...

Abstract

The invention discloses an automatic market analysis method based on multi-mode learning. The automatic market analysis method comprises the steps that firstly, a learning device is trained, and then in practical use, the trained learning device is used for predicting a market. A method for training the learning device comprises the steps that firstly, different-mode information of the market is collected and labeled; then, a multi-example generating method of market data features and character features is used for converting low-level features into a multi-example-packet format; finally, a multi-example multi-label learning method capable of utilizing various modes is adopted to conduct fusion processing on the data, and multi-label learning is conducted. According to the automatic market analysis method based on multi-mode learning, by acquiring multiple pieces of side information of the market, market changes can be depicted more comprehensively and market changes can be predicted more accurately. According to the method for conducting market prediction by using the multi-mode information, the different-mode data information can be used in the implementation process, adaptability is high and effects are good.

Description

technical field [0001] The present invention belongs to the field of automated market analysis methods, in particular to an automated market analysis method based on multimodal learning. Background technique [0002] Algorithmic trading, which uses a computer platform to input trading orders by executing a pre-set trading strategy, has become one of the mainstream trading methods at present. Considering that the composition of the market microstructure is restricted by various constraints, that is, the micro market conditions are related to multiple different sources of information. However, most of the current algorithmic trading methods tend to focus on one side of the market, such as price or related news reports, and only consider a single factor and take it into consideration as a decisive factor. This method leads to the inability of automatic trading algorithms to obtain comprehensive market information. , so that it is difficult to grasp the changes in the market, w...
