Pseudocode No The paper describes the method and uses equations, but does not include structured pseudocode or algorithm blocks.
Open Source Code Yes The code is available at https://github.com/jytime/DICL-Flow.
Open Datasets Yes The paper uses well-known public datasets: Flying Chair [5], Flying Things [21], Sintel [3], and KITTI [23], all with proper citations.
Dataset Splits Yes The paper mentions training on 'Flying Chair', 'Flying Things', 'Sintel', and 'KITTI' datasets, and refers to 'Flying Chair validation dataset' in Table 3's ablation study. This implies the use of standard, predefined splits for these well-known benchmarks.
Hardware Specification Yes The training details state: 'We use a batch size of 8 per GPU on the Flying Chair and 2 on other datasets, with 8 NVIDIA 1080 Ti GPUs for training.'
Software Dependencies No The paper does not provide specific software dependencies with version numbers (e.g., Python, PyTorch, CUDA versions) needed to replicate the experiment.
Experiment Setup Yes The paper provides extensive experimental setup details including learning rates (0.001, 0.00025), training iterations (150K, 220K, 60K), learning rate drop schedules (half after 120K, at 30K, 50K), batch sizes (8, 2), loss function (multi-level ℓ2 loss with specific weights 1.0, 0.75, 0.5, 0.5, 0.5), and augmentation strategies (random resizing, cropping, flipping, color jittering, asymmetric occlusion).
