WebbThe main principle behind SFA is called the slowness principle, which is complemented in HiGSFA by information preservation as well as by additional heuristics, such as hierarchical processing (hierarchical SFA), multiple label learning, the use of deep network architectures, and normalized nonlinear expansion functions. Webb感兴趣的特征在空间缓慢连续移动 (Slowness Principle) ，即很小概率发生突变。 例如上抛一个小球，他下一刻和上一刻的位移变化不会特别大，不会“闪现”,具有空间和时间连续性。 \mathcal {L}_ {Slowness} (D,\phi)=\mathbb {E} [ \Delta s_t ^2] 关注可变性 (Variability) 。 即关注场景中变化或者移动的部分，比如在上面提到的弹球游戏中，我们可能更关注弹 …
Slow Feature Analysis: Perspectives for Technical …
The slowness principle is based on the observation that different representations of a sensorial input vary on different time scales. For instance, a zebra grazing in the savanna is a scene that changes slowly. This scene is represented in the eyes of an observer in terms of activities of retinal receptors, which, due to … Visa mer Most learning algorithms based on the slowness principle are online learning rules, i.e., they improve the extracted features incrementally with each time step of the … Visa mer SFA has been developed for learning invariant representations of moving objects in a feedforward model of the visual system. It has been shown that a … Visa mer WebbThe slowness principle is one of the learning paradigms that might explain the self-organization of neurons in the brain to extract invariant representations (e.g. Franzius et al., 2007). This principle operates on an abstract level of information processing and postulates that perceived information relevant to a subject typically changes much ... can any car battery fit any car
