FactorVAE: A Probabilistic Dynamic Factor Model Based on Variational Autoencoder for Predicting Cross-Sectional Stock Returns

Yitong Duan, Lei Wang, Qizhong Zhang, Jian Li
2022 AAAI Conference on Artificial Intelligence  
Essentially, our model integrates the dynamic factor model (DFM) with the variational autoencoder (VAE) in machine learning, and we propose a prior-posterior learning method based on VAE, which can effectively  ...  In this paper, we propose a novel factor model, FactorVAE, as a probabilistic model with inherent randomness for noise modeling.  ...  Acknowledgements The research is supported in part by the National Natural Science Foundation of China Grant 62161146004, Turing AI Institute of Nanjing and Xi'an Institute for Interdisciplinary Information  ...
