| Research Type | Theoretical | In this paper, we present the first end-to-end error analysis of CNFs built upon FM. Our analysis shows that for general target distributions with bounded support, the generated distribution of FM is guaranteed to converge to the target distribution in the sense of the Wasserstein-2 distance. Furthermore, the convergence rate is significantly improved under an additional mild Lipschitz condition of the target score function. |

| Pseudocode | No | The paper contains mathematical derivations and proofs (e.g., Theorem 1.6, Theorem 1.7, Lemma 4.1, etc.) but no structured pseudocode or algorithm blocks are present. |
| Open Source Code | No | The paper does not contain any explicit statements regarding the release of open-source code, nor does it provide links to code repositories. |
| Open Datasets | No | The paper analyzes properties of Flow Matching using theoretical constructs such as 'n samples from target distribution π1' and 'the standard Gaussian distribution as the prior distribution, i.e., π0 = N(0, Id)', but does not use or provide concrete access information for any publicly available or open datasets. |
| Dataset Splits | No | As a theoretical paper, it does not describe experimental evaluation on specific datasets and therefore does not provide information on training/test/validation dataset splits. |
| Hardware Specification | No | The paper is a theoretical work focusing on error analysis and mathematical proofs; thus, it does not mention any specific hardware used for experiments. |
| Software Dependencies | No | The paper is theoretical and does not describe an implementation or experimental process that would require specific software dependencies or versions. |
| Experiment Setup | No | The paper focuses on theoretical error analysis and mathematical proofs, and therefore does not include details about an experimental setup, hyperparameters, or system-level training settings. |
