为了解释复杂和模糊的输入，人类视觉系统使用对世界的先验知识或假设。我们表明，用于从阴影中提取形状信息的“上方光线”先验会根据场景的活动经验进行修改。由此产生的适应不是特定于学习场景，而是推广到不同的任务，这表明先验是通过与环境的互动经验不断适应的。
To interpret complex and ambiguous input, the human visual system uses prior knowledge or assumptions about the world. We show that the `light-from-above' prior, used to extract information about shape from shading is modified in response to active experience with the scene. The resultant adaptation is not specific to the learned scene but generalizes to a different task, demonstrating that priors are constantly adapted by interactive experience with the environment.
