Reproducibility Variable Result LLM Response
Research Type Experimental We empirically investigate Multisample Flow Matching on a suite of experiments. First, we show how different couplings affect the model on a 2D distribution. We then turn to benchmark, high-dimensional datasets, namely Image Net (Deng et al., 2009).

Pseudocode Yes Algorithm 1 Stable Coupling (Gale Shapely) and Algorithm 2 Heuristic Coupling
Open Source Code No The paper does not provide an explicit statement or link indicating that the source code for the proposed Multisample Flow Matching method is publicly available.
Open Datasets Yes We use the official face-blurred Image Net data and then downsample to 32x32 and 64x64 using the open source preprocessing scripts from Chrabaszcz et al. (2017). Image Net (Deng et al., 2009).
Dataset Splits No The paper uses ImageNet data for experiments but does not explicitly provide details on how the dataset was split into training, validation, and test sets, or refer to specific predefined splits with citations.
Hardware Specification No The paper does not provide specific hardware details such as GPU models, CPU types, or other hardware specifications used for running the experiments.
Software Dependencies No The paper mentions using 'torchdiffeq' (Chen, 2018) and the 'Tensor Flow-GAN' library, but it does not provide specific version numbers for these or other software dependencies.
Experiment Setup Yes Table 10. Hyper-parameters used for training each model. It includes details such as Channels, Depth, Batch size / GPU, GPUs, Epochs, Learning Rate, and Learning Rate Scheduler for Image Net-32 and Image Net-64.
