Pseudocode No The paper describes the algorithms for its three models (Sampling Importance Network, Latent Encoder Network, Denoiser) in Section 2.3, but it does not present them in a structured pseudocode or algorithm block format.
Open Source Code Yes We release our dataset scenes and code implementation1 to facilitate the usage and comparison of our method. 1Source code available at https://github.com/AJSVB/RL_PATH_TRACING.
Open Datasets Yes We use three 3D scenes Emerald Square [40], Sun Temple [41], and Zero-Day [42] released as part of the Open Research Content Archive (ORCA) under CC BY 4.0 license.
Dataset Splits No The paper mentions 'cross-validated results for each scene: For every test scene, we train on all the other scenes', which describes a cross-validation strategy but does not specify explicit training/validation/test dataset splits (percentages or counts) for a single dataset.
Hardware Specification Yes We perform our measurements on a Nvidia Ge Force RTX 2080 Ti GPU.
Software Dependencies No The paper states 'We use Adam optimizer [38], Pytorch and Ray-RLlib [39]' but does not provide specific version numbers for these software components.
Experiment Setup Yes All networks are trained in a closed loop on 100 epochs with a batch size of 4. ... the learning rate has a maximum value of 0.1 and a minimum value of 10 8, with a warmup phase of 15%, and then an exponential decay phase. ... We transform the images by using vertical and/or horizontal flips, by randomly cropping and rescaling the images.
