Implementation Details 3 Method The main idea behind our method is to develop a form of denoising diffusion models analogous to image diffusion models for syntax trees. Consider the example task from Ellis et al. [11] of generating a constructive solid geometry (CSG2D) program from an image. In CSG2D, we can combine simple primitives like circles and quadrilaterals using boolean operations like addition and subtraction to create more complex shapes, with the context-free grammar (CFG), In the following sections, we will first describe how “noise” is added to syntax trees. Then, we will detail how we train a neural network to reverse this noise. Finally, we will describe how we use this neural network for search. Authors:
