In this paper, the authors introduce a new family of models called Closed-form Continuous-depth (CfC) networks. These networks are designed to process sequential data and overcome the limitations of existing continuous-depth neural models that rely on advanced numerical differential equation solvers. The CfC networks are derived from the analytical closed-form solution of a subset of time-continuous models, eliminating the need for complex DE solvers. The authors demonstrate that CfC networks are not only simpler to describe but also significantly faster compared to their ODE-based counterparts, with at least one order of magnitude reduction in computational cost. Despite their simplicity and efficiency, CfC networks exhibit equally strong modeling abilities as advanced recurrent models. Experimental evaluations show that CfC networks outperform recurrent models in various time-series prediction tasks, including those with long-term dependencies and irregularly sampled data. This suggests that CfC networks have the potential to be deployed in resource-constrained settings where both performance and efficiency are crucial. Furthermore, the authors discuss the application of CfC networks in two specific domains. Firstly, they apply these models to the PhysioNet Challenge 2012 dataset, which involves predicting the mortality of ICU patients based on time series medical measurements. Secondly, they explore sentiment analysis using the IMD dataset. Overall, this research presents an innovative approach to training and deploying continuous neural models by leveraging closed-form solutions instead of relying on complex DE solvers. The findings highlight the potential for CfC networks to improve performance and efficiency in various sequential data processing tasks.

Abstract: Continuous-depth neural models, where the derivative of the model's hidden state is defined by a neural network, have enabled strong sequential data processing capabilities. However, these models rely on advanced numerical differential equation (DE) solvers resulting in a significant overhead both in terms of computational cost and model complexity. In this paper, we present a new family of models, termed Closed-form Continuous-depth (CfC) networks, that are simple to describe and at least one order of magnitude faster while exhibiting equally strong modeling abilities compared to their ODE-based counterparts. The models are hereby derived from the analytical closed-form solution of an expressive subset of time-continuous models, thus alleviating the need for complex DE solvers all together. In our experimental evaluations, we demonstrate that CfC networks outperform advanced, recurrent models over a diverse set of time-series prediction tasks, including those with long-term dependencies and irregularly sampled data. We believe our findings open new opportunities to train and deploy rich, continuous neural models in resource-constrained settings, which demand both performance and efficiency.
