摘要:

人的认知具有组合性。我们通过将场景分解为不同的概念来理解场景(例如,物体的形状和位置),并学习这些概念的各自规律,这些规律可以是自然的(例如,运动定律)或人为的(例如,游戏规则)。这些法律的自动解析表明模型的理解场景的能力,这使得法律解析在许多视觉任务中发挥着核心作用。提出了一种用于组合式LAw解析(CLAP)的深层潜变量模型,该模型通过编码-解码架构将场景中的概念表示为潜变量,实现了类似人类的组合能力。CLAP采用神经过程实例化的概念特定的潜在随机函数来捕获概念的规律。我们的实验结果表明,CLAP优于基线方法在多个视觉任务,如直观的物理,抽象的视觉推理,场景表示。通过修改样本上的特定潜在随机函数,法律操作实验说明了CLAP的可解释性。例如,CLAP从场景中移动的球中学习位置变化和外观恒定性的规律,从而可以在样本之间交换规律或将现有的规律组合成新的规律。

英文摘要:

Human cognition has compositionality. We understand a scene by decomposing the scene into different concepts (e.g., shape and position of an object) and learning the respective laws of these concepts, which may be either natural (e.g., laws of motion) or man-made (e.g., laws of a game). The automatic parsing of these laws indicates the model's ability to understand the scene, which makes law parsing play a central role in many visual tasks. This paper proposes a deep latent variable model for Compositional LAw Parsing (CLAP), which achieves the human-like compositionality ability through an encoding-decoding architecture to represent concepts in the scene as latent variables. CLAP employs concept-specific latent random functions instantiated with Neural Processes to capture the law of concepts. Our experimental results demonstrate that CLAP outperforms the baseline methods in multiple visual tasks such as intuitive physics, abstract visual reasoning, and scene representation. The law manipulation experiments illustrate CLAP's interpretability by modifying specific latent random functions on samples. For example, CLAP learns the laws of position-changing and appearance constancy from the moving balls in a scene, making it possible to exchange laws between samples or compose existing laws into novel laws.
