Abstract: A video bitstream comprising a current picture of a video is received. A first group of samples and a second group of samples in the current picture are determined. A first geometric transform is determined for the first group of samples in the current picture and a second geometric transform is determined for the second group of samples in the current picture. The first geometric transform is configured to adjust an orientation of the first group of samples in the current picture. The second geometric transform is different from the first geometric transform and configured to adjust an orientation of the second group of samples in the current picture. The picture is reconstructed, where the first group of samples is reconstructed based on the determined first geometric transform and the second group of samples is reconstructed based on the determined second geometric transform.

Abstract: Aspects of the disclosure include methods and apparatuses for video coding. One of the apparatuses includes processing circuitry that receives a bitstream of a current block in a current picture. The current block is coded with a directional nearest neighbor prediction (DNNP) mode. The processing circuitry selects a prediction value for a sample in the current block from a top-left value, a top value, or a left value based on one or more difference values between respective paired values of (i) the top-left value associated with a top-left reference sample that is a top-left neighbor of the current block, (ii) the top value associated with a top reference sample that is a top neighbor of the sample in the current block, and (iii) the left value associated with a left reference sample that is a left neighbor of the sample in the current block. The processing circuitry reconstructs the current block using the selected prediction value for the sample in the current block.

Abstract: The present disclosure describes techniques for determining performance of a classifier. A first machine learning model and a second machine learning model may be trained by aggregating updates to the first machine learning model and the second machine learning model received from a plurality of client computing devices. A cumulative distribution function (CDF) associated with a distribution of the positive samples in the user data may be estimated using the trained first machine learning model. A probability density function (PDF) associated with a distribution of the negative samples in the user data may be estimated using the trained second machine learning model. An integration-based computation of an area under the receiver operating characteristic curve (AUC) of the classifier may be performed using the PDF and the CDF.
