The present disclosure relates to systems, non-transitory computer-readable media, and methods for intelligently predicting a persona class of a client device and/or target user utilizing an overlap-agnostic machine learning model and distributing persona-based digital content to the client device. In particular, in one or more embodiments, the persona classification system can learn overlap-agnostic machine learning model parameters to apply to user traits in real-time or in offline batches. For example, the persona classification system can train and utilize an overlap-agnostic machine learning model that includes an overlap-agnostic embedding model, a trained user-embedding generation model, and a trained persona prediction model. By applying the learned overlap-agnostic machine learning model parameters to the target user traits, the persona classification system can predict a persona class for sending digital content based on the predicted persona class.

A method for detecting the endpoint of a chemical mechanical polishing (CMP) process uses the slope variation of temperature difference of polishing pad. The method combines temperature measurement at polishing pad and atmosphere, and numerical analysis to figure out the curve of temperature difference variation versus polishing time. The endpoint of CMP is determined by the change of the slope of the curve. The method allows endpoint to be detected in-situ at the polishing apparatus, without stopping polishing process.

A method for trading in a financial derivative of an underlying asset includes determining a trend predictive of a future value of the asset and a predicted variance of the future value. Responsive to the trend and the variance, a density function is calculated, which is indicative of a probability distribution of the value at a first time in the future. Based on the density function at the first time, the density function is recalculated to find the probability distribution of the value at a second time, subsequent to the first time, and a trading decision is made with regard to the derivative of the asset based on the density function.

A computer-implemented method for optimizing the design of an electromagnetic coil arrangement that generates a uniform magnetic field in a desired region, with the electromagnetic coil arrangement having a number of coils and a shape defined by r and z, where r is the radial coordinate of a cylindrical coordinate system having (r, z, phi) coordinates, and z is the axial coordinate of the cylindrical coordinate system. The method has an important use for designing superconductive or resistive coil arrangements for MRI systems. The core of the method is to compute a solution to a master equation (25) for a set of parameters lambda_j which define the coil arrangement and the currents needed. An important advantage is that the resultant coil arrangement has a minimum volume, which saves on material, or uses a minimum power.
