Abstract: An online system uses a trained machine-learning model for dynamically modifying an authorization buffer amount to cover additional expenses occurring during fulfillment of an online order. Upon receiving a signal indicating that a user entered an online checkout stage of the order, the online system applies the machine-learning model to generate a set of values of a metric for a set of authorization buffer amounts, each value of the metric resulting from charging the user a respective authorization buffer amount over an expected value of the order if a value of the order at delivery is greater than the expected value. The online system selects an authorization buffer amount resulting in the largest value of the metric, and generates an authorization signal that authorizes charging the user the authorization buffer amount over the expected value if the value of the order is greater than the expected value.

Abstract: In some embodiments, a method includes inputting a proxy encoding configuration into an encoder. This encoder determines proxy quality values from an actual encoding of a portion of a video. These proxy quality values are for a set of bitrates and a resolution. The method also determines target feature values for the same portion of the video. The method inputs both the target feature values and a target configuration into a prediction network. This network generates a plurality of quality offset values for the set of bitrates and the resolution. The prediction network is configured to predict an offset to the proxy quality values. This offset is determined based on a difference between the proxy encoding configuration and the target configuration. The method then generates a plurality of quality values. The generation uses the plurality of proxy quality values and the corresponding plurality of quality offset values.

A sequence of frames in the new version of the first video is different from the first video. The method compares frames of the new version of the second video and frames of the new version of the first video to generate a score based on a quality metric.

Abstract: A star rating management method for deployment and implementation of gas field development wells first establishes the expression for estimating the gas well initial production rate and the dimensionless production curve; then determines the annual production of the new well for every year during the evaluation period and determines the internal rate of return of the new gas well. If the internal rate of return fails to meet the requirement, the deployment location and construction technology of the new well are re-optimized. Corresponding stars rating are determined according to the internal rate of return of the gas wells. The new well is drilled according to the deployment location that can meet the economic benefit requirements. After the gas well is drilled, a more detailed fracturing design is carried out, and the internal rate of return of the gas well and the star rating of development benefit are redetermined.
