While powerful, researchers have noted it can sometimes produce "disconnected density predictions" that might violate certain laws like mass conservation in specific 3D settings. 2. Software & File Compression: [OT] RAR
It uses Optimal Transport theory to adaptively select "collocation points" (data points) in areas where the model is struggling most, helping the neural network learn physical laws more accurately.
