In some embodiments, a method determines a reward metric based on feedback for an instance of content. A delivery status for a delivery constraint of the instance of content is applied to the reward metric to generate a constrained reward metric. The method uses the constrained reward metric to train a model. The model is used to select from a plurality of instances of content. One of the plurality of instances of content is selected for delivery using the model.

Reinforcement learning for delivery of content

In some embodiments, a method receives a request for supplemental content to be provided in association with main content. The method selects an instance of supplemental content based on a long-term reward metric and a short-term reward metric. The long-term reward metric is based on feedback from delivery of a plurality of instances of supplemental content and a delivery status for a delivery constraint of one instance of supplemental content. The short-term reward metric is based on feedback from delivery of the one instance of supplemental content. The long-term reward metric is based on feedback from delivery of a plurality of instances of supplemental content and the short-term reward metric is based on feedback from delivery of one instance of supplemental content. The instance of supplemental content is provided to a client device.

Reinforcement learning for guaranteed delivery of supplemental content

The present invention relates to a detection mechanism for polymerase chain reaction and a polymerase chain reaction device, wherein the detection mechanism comprises at least one excitation module group, each of the excitation module groups comprising two excitation modules for providing excitation light with two wavelengths; an excitation optical fiber, connected to the excitation modules, the excitation optical fiber transmitting the excitation light to at least one reaction tube, each of the reaction tubes receiving excitation light with two wavelengths; a receiving optical fiber, for collecting and transmitting a fluorescent signal from the reaction tube; at least one receiving module group, connected to the receiving optical fiber, each of the receiving module groups comprising two receiving modules, to respectively receive the fluorescent signal of two wavelengths from the same said reaction tube, and convert the fluorescent signal into an electrical signal for output; the detection mechanism is configured to detect the reaction tube in a time division manner, and multiplex the receiving module group to obtain an output result.
