This study investigates the architectural choices of modern time-dependent neural networks, specifically the neural ordinary differential equation (ODE) and diffusion models. Researchers have proposed time-dependent neural networks to model dynamical systems that evolve over time, but the impact of this architectural choice on their time-awareness remains unclear. The authors claim that the current state of these networks lacks sufficient validation and identify a vulnerability in vanishing timestep embedding, which disables their time-awareness. They also find that this issue can be observed in diffusion models due to their similar architecture. The study provides solutions to address the root cause of this problem and experimentally verifies the effectiveness of these solutions on neural ODEs and diffusion models.

This paper looks at how we design neural networks to understand things that change over time, like weather patterns or stock prices. Right now, there are some problems with these designs that make them less effective than they could be. The researchers found a specific issue where the network’s ability to understand time is lost when using certain techniques. They also show that this problem can occur in other types of networks used for similar tasks. To fix this, they propose some solutions and test them on different kinds of neural networks.
