Stock Trend Prediction with Multi-Granularity Data: A Contrastive Learning Approach with Adaptive Fusion
- Multi-granularity
- Cross-Granularity and Cross-Temporal contrast learning
- Modeling relations between related stocks' temporal price movement
- Using profitable metrics and NDCG for ranking
- Using Hawkes process as temporal attention
Stock market forecasting using a multi-task approach integrating long short-term memory and the random forest framework
CCF None
- An awesome table (table 1) Describes 43 technical indicators.
Using normalized Mutual Information as relations?
- d
- Multi-task
- Classify noise-free samples and noisy samples
- Cross-updating inspired bt co-training to overcome sample-selection bias
- Considering 2 different scale behavior by wavelet-based XGBoost and down-sampling-based RCNN
- Datasets: FI-2010 and CSI-2016
Long-term, Short-term and Sudden Event: Trading Volume Movement Prediction with Graph-based Multi-view Modeling
- valuable target for further study
- Predict trading volume instead of price
- Emphasis on multi-view information, including long-term stock relation, short-term fluctuations and sudden events
- model multiple stock trading patterns
- the lack of explicit identifiers makes it quite challenging to train a router. So they design a learning algorithm based on Optimal Transport
Investment Behaviors Can Tell What Inside: Exploring Stock Intrinsic Properties for Stock Trend Prediction
- leverage stock intrinsic properties
- extract stock intrinsic properties from mutual fund portfolios
- use static stock properties in a dynamic way by measuring the correlation between the market and the stock
-
the representation of stock properties
$Q^j$ extracted from fund managers' preference
-
dynamic correlation
Why not
$\hat{r}_{t+1}^j=MLP([\hat{D}_t^j,Q^j])$ ? The static stock properties cannot explicitly predict the stock trend in dynamic marketmarket state: take $Q^j$s whose return ratio is ranked within top-$K_r$ at time t and average those
$K_r$ $Q^j$s.then correlation
$D_t^j=S_tQ^j$ - dynamic market state $\hat{D}t^j \approx D{t-1}^j$
- dynamic market trend predict $\hat{S}t=LSTM(S{<t})$
-
predict return ratio
$\hat{r}_{t+1}^j=MLP([\hat{D}_t^j,Z_t^j])$ -
$\hat{D}_t^j$ is the correlation -
$Z_t^j$ is embedding of stock's past performance, e.g. history price
