Abstract: In some implementations, a computing device determines an event timeline that comprises one or more finance-related events associated with a person. A production classifier may be used to determine (i) an individual contribution of each event in the event timeline to a financial capacity of the person and (ii) a first decision regarding whether to extend credit to the person. A bias monitoring classifier may, based on the event timeline, determine a second decision whether to extend credit to the person. The bias monitoring classifier may be trained using pseudo-unbiased data. If a difference between the first decision and the second decision satisfies a threshold, the production classifier may be modified to reduce bias in decisions made by the production classifier.

Abstract: A plyometric exercise ladder. A frame has two, spaced-apart, upright posts. A fixed arm is mounted to each upright post, each fixed arm being adjustable along the length of the frame. A removable pull-up bar is supported by the fixed arms. Two spring-loaded arms disposed above the fixed arms are pivotally mounted to the upright posts of the frame. An electromagnet is connected to each spring-loaded arm for initiating movement. A freestanding bracket having at least one scissor arm is connected to the frame and to a wall or other solid structure to support the ladder. In place of the spring-loaded arms and electromagnet, a set of pegs can be removably placed along the length of the upright posts for retaining the pull-up bar as an athlete progresses upwardly. The ladder frame itself can be replaced with a skeletal frame when the ladder is used in conjunction with a conventional squat rack.
