Abstract: A user preference hierarchy is determined from user response to images. Images may be tagged using machine learning models trained to determine values for images. Products are clustered according to product vectors. Images of products within a cluster are clustered according to composition and groups of images are selected from image clusters for soliciting feedback regarding user preference for products of a cluster. Feedback is used to train a user preference model to estimate affinity for a product vector. A user may provide feedback regarding a price point and products are weighted according to a distribution about the price point. The distribution may be asymmetrical according to direction of movement of the price point. Filters may be dynamically defined and presented to a user based on popularity and frequency of occurrence of attribute-value pairs of search results and based on feedback regarding the search results.

Abstract: A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.
