Stock market forecasting with super-high dimensional time-series data using ConvLSTM, trend sampling, and specialized data augmentation

作者:

Highlights:

• Our model learns high-level features from super-high dimensional time-series data.

• All companies’ price data in the relevant country’s open market are used as input.

• The trend sampling mini-batch sampling method enhances forecasting performance.

• Experimental results show that our model adapts to real-time patterns.

• The model outperforms others with the same training and testing conditions.
