The process of generating data such as images is controlled by independent and unknown factors of variation. The retrieval of these variables has been studied extensively in the disentanglement, causal representation learning, and independent component analysis fields. Recently, approaches merging these domains together have shown great success. Instead of directly representing the factors of variation, the problem of disentanglement can be seen as finding the interventions on one image that yield a change to a single factor. Following this assumption, we introduce a new method for disentanglement inspired by causal dynamics that combines causality theory with vector-quantized variational autoencoders. Our model considers the quantized vectors as causal variables and links them in a causal graph. It performs causal interventions on the graph and generates atomic transitions affecting a unique factor of variation in the image. We also introduce a new task of action retrieval that consists of finding the action responsible for the transition between two images. We test our method on standard synthetic and real-world disentanglement datasets. We show that it can effectively disentangle the factors of variation and perform precise interventions on high-level semantic attributes of an image without affecting its quality, even with imbalanced data distributions.

通过将因果关系理论与矢量量化变分自编码器相结合，我们提出了一种新的基于因果动态的去纠缠方法，将量化向量视为因果变量并将其链接在因果图中，通过对因果图进行因果干预，引发影响图像中唯一变化因素的原子转换。同时，我们通过引入一个新的行动检索任务来测试我们的模型。我们在标准的合成和真实世界的去纠缠数据集上进行了测试，结果表明它能够有效地解缠图像变化因素并对图像的高级语义属性进行精确干预，而不影响其质量，即使在不均衡的数据分布下也是如此。
