Pseudocode No The paper describes methods and algorithms but does not contain a clearly labeled pseudocode or algorithm block.
Open Source Code Yes Details of the further analyses are provided in the appendix, which is available at: https://github.com/ailearn-ml/RDA.
Open Datasets Yes We curate six ILDL benchmarks that span movie rating, facial beauty perception and visual sentiment distribution perception. These datasets are sampled from six standard LDL datasets, including Movie (Geng 2016), SCUT-FBP (Xie et al. 2015), Emotion6 (Peng et al. 2015), Flickr LDL (Yang, Sun, and Sun 2017), RAF-ML (Shang and Deng 2019) and Natural Scene (Geng 2016).
Dataset Splits Yes The sampling process is performed 10 times, for each time, we sample the training set and validation set from the original training set which occupies 90% of the examples, while the test set remains unchanged.
Hardware Specification No The paper does not provide specific details about the hardware (e.g., GPU models, CPU types, memory) used for running the experiments.
Software Dependencies No The paper does not provide specific software dependencies with version numbers (e.g., Python 3.8, PyTorch 1.9).
Experiment Setup Yes In RDA, gϵ, hφ and Fϑ are set as linear projections, Gε and Hϕ are set as single-layer neural network with two outputs including mean and variance of Gaussian, and the modified distribution-balanced focal loss is adopted as the loss function V . Hyperparameters λ1, λ2 and λ3 are selected by grid search from the set {0.01, 0.05, 0.1, 0.2, 0.5}.
