This Paper Explores Efficient Predictive Control with Sparsified Deep Neural Networks

Robotics is currently exploring find out how to enhance complex control tasks, resembling manipulating objects or handling deformable materials. This research area of interest is crucial because it guarantees to bridge the gap between current robotic capabilities and the nuanced dexterity present in human actions.

A central challenge on this area is developing models that may accurately indicate the outcomes of robotic actions in dynamic environments. Particularly in tasks involving intricate contact dynamics, there’s a necessity for models that may adeptly handle complexity without compromising accuracy. The crux of the issue is creating models that may efficiently navigate these demanding scenarios while delivering reliable performance.

Conventional methods on this field have heavily relied on deep neural networks (DNNs) as a consequence of their exceptional ability to model complex patterns. Nonetheless, the high nonlinearity of DNNs presents significant challenges in planning and control tasks. These tasks often necessitate extensive computational methods, resembling sampling or gradient descent, which may fall short in scenarios requiring complex, long-horizon planning.

To deal with these limitations, a framework has been introduced by researchers from Cornell University, Stanford University, Massachusetts Institute of Technology, and University of Illinois Urbana-Champaign. This framework revolves across the concept of sparsifying neural dynamics models. Sparsification is a process that goals to streamline the model by systematically reducing its nonlinearity. That is achieved by selectively removing or replacing neurons, rendering the model more tractable for optimization processes.


The essence of this sparsification process is to strike a balance between the simplicity of the model and its functional performance. By rigorously reducing the model’s nonlinearity, the researchers have maintained a commendable level of prediction accuracy. This simplification enables the efficient application of mixed-integer programming in model-based control, thereby improving the model’s performance in closed-loop control scenarios.

Empirical results underscore the effectiveness of this approach. Despite their streamlined architecture, the sparsified models perform on par with or higher than their more complex counterparts in predictive accuracy and closed-loop control tasks. This equilibrium between simplicity and efficiency is especially noteworthy, because it suggests a sweet spot where the models retain sufficient predictive power while benefiting from more practical optimization tools.

This research represents a big leap in the sphere of robotics, highlighting the potential of simpler yet effective models in enhancing the efficiency and adaptableness of robotic control systems. The study conducted could be presented in a nutshell in the next points:

  • Crafting predictive models for complex automated control tasks.
  • Reduction of model complexity through neural network sparsification.
  • Gradual decrease of nonlinearity in neural models, optimizing them for efficient use in automatic control.
