Reproducibility Variable Result LLM Response
Research Type Experimental We conduct a variety of experiments to evaluate the presented approach. We begin by comparing to other differentiable physics frameworks, with particular attention to scalability and generality. We then conduct ablation studies to evaluate the impact of the techniques presented in Sections 5 and 6. Lastly, we provide case studies that illustrate the application of the presented approach to inverse problems and learning control.
Researcher Affiliation Collaboration 1University of Maryland, College Park 2Intel Labs.
Pseudocode No The paper describes methods and derivations but does not include explicitly labeled pseudocode or algorithm blocks.
Open Source Code Yes Code is available on our project page: https://gamma.umd.edu/researchdirections/mlphysics/diffsim
Open Datasets No The paper describes custom benchmark scenes and application scenarios (e.g., 'cubes are stacked', 'marble is supported by a soft sheet') but does not specify or provide access information for any publicly available or open datasets.
Dataset Splits No The paper does not provide specific dataset split information (e.g., percentages, sample counts, or citations to predefined splits) for training, validation, or testing.
Hardware Specification Yes All experiments are run on an Intel(R) Xeon(R) W-2123 CPU @ 3.60GHz.
Software Dependencies Yes The automatic differentiation is implemented in Py Torch 1.3 (Paszke et al., 2019).
Experiment Setup Yes The neural network is an MLP with 50 nodes in the first layer and 200 nodes in the second, with Re LU activations. In each episode, we fix the initial position of the manipulator and the object while the target position is randomized.
