- Abstract: In recent years, the dynamic factor model has emerged as a dominant tool in
economics and finance, particularly for investment strategies. This model
offers improved handling of complex, nonlinear, and noisy market conditions
compared to traditional static factor models. The advancement of machine
learning, especially in dealing with nonlinear data, has further enhanced asset
pricing methodologies. This paper introduces a groundbreaking dynamic factor
model named RVRAE. This model is a probabilistic approach that addresses the
temporal dependencies and noise in market data. RVRAE ingeniously combines the
principles of dynamic factor modeling with the variational recurrent
autoencoder (VRAE) from deep learning. A key feature of RVRAE is its use of a
prior-posterior learning method. This method fine-tunes the model's learning
process by seeking an optimal posterior factor model informed by future data.
Notably, RVRAE is adept at risk modeling in volatile stock markets, estimating
variances from latent space distributions while also predicting returns. Our
empirical tests with real stock market data underscore RVRAE's superior
performance compared to various established baseline methods.

Early-exit architectures enable the development of dynamic models capable of adapting their size and architecture to varying levels of computational resources and ASR performance demands.
We show that early-exit models trained from scratch not only preserve performance when using fewer encoder layers but also exhibit enhanced task accuracy compared to single-exit or pre-trained models.

It is still an open question to build a factor model that can conduct stock prediction in an online and adaptive setting.
We propose the first deep learning based online and adaptive factor model, HireVAE, at the core of which is a hierarchical latent space that embeds the relationship between the market situation and stock-wise latent factors.
Across four commonly used real stock market benchmarks, the proposed HireVAE demonstrate superior performance in terms of active returns over previous methods.
