Forecasting Variation Trends of Stocks via Multiscale Feature Fusion and Long Short-Term Memory Learning
نویسندگان
چکیده
Forecasting stock price trends accurately appears a huge challenge because the environment of markets is extremely stochastic and complicated. This persistently motivates us to seek reliable pathways guide trading. While Long Short-Term Memory (LSTM) network has dedicated gate structure quite suitable for prediction based on contextual features, we propose novel LSTM-based model. Also, devise multiscale convolutional feature fusion mechanism model extensively exploit relationships hidden in consecutive time steps. The significance our designed scheme twofold. (1) Benefiting from both long- short-term memories, can use given history data more adaptively than traditional models, which greatly guarantees performance financial series (FTS) scenarios thus profits trends. (2) diversify representation capture FTS essence fairly facilitates generalizability. Empirical studies conducted three classic sets, i.e., S&P 500, DJIA, VIX, demonstrated effectiveness stability superiority suggested method against few state-of-the-art models using multiple validity indices. For example, achieved highest average directional accuracy (around 0.71) employed sets.

Reinforcement Learning with Long Short-Term Memory
This paper presents reinforcement learning with a Long ShortTerm Memory recurrent neural network: RL-LSTM. Model-free RL-LSTM using Advantage( ) learning and directed exploration can solve non-Markovian tasks with long-term dependencies between relevant events. This is demonstrated in a T-maze task, as well as in a di cult variation of the pole balancing task.

In this paper, we use variational recurrent model to investigate the time series forecasting problem. Combining recurrent neural network (RNN) and variational inference (VI), this model has both deterministic hidden states and stochastic latent variables while previous RNN methods only consider deterministic states. Based on comprehensive experiments, we show that the proposed methods significa...

We explored whether individual features and bindings between those features in VSTM tasks are completely lost from trial to trial or whether residual memory traces for these features and bindings are retained in long-term memory. Memory for arrays of coloured shapes was assessed using change detection or cued recall. Across trials, either the same colour-shape (integrated object) combinations w...
