Reproducibility Variable Result LLM Response
Research Type Experimental Experiments manifest DDN achieves the best results on diversified univariate and multivariate CDE tasks in comparison with six different explicit CDE models. This section examines the efficacy of DDN for explicitly estimating free-form conditional PDF on continuous-domain.

Pseudocode No The paper describes the architecture and functionality of the Deconvolutional Density Network (DDN) through text and diagrams (Fig. 2), but it does not provide a formal pseudocode block or algorithm.
Open Source Code Yes The code of DDN is available at https://github.com/NBICLAB/DDN
Open Datasets Yes The validation also included seven real-world datasets from the UCI machine learning repository (Dua and Graff 2017).
Dataset Splits Yes For each trial, we randomly split the data into a training set and test set with a ratio of 3:7, to mimic data deficiency scenario.
Hardware Specification Yes All experiments were running on a Tesla V100 GPU.
Software Dependencies No The paper mentions using 'Adam optimizer' but does not specify software dependencies like programming languages (e.g., Python), libraries (e.g., PyTorch, TensorFlow), or their specific version numbers.
Experiment Setup Yes The learning rate was set to 3e-4, and the batch size was 256. The models were trained independently for 10 trials on each dataset, with 3000 epochs per experiment. In all experiments, the estimator of our DDN contained two Upsample-Conv-Batch Norm-Leaky Re LU blocks and one Upsample-Conv block in each target dimension. We configured the blocks so that the output space was partitioned into N = 256 bins.
