Example systems perform complex optimization tasks with improved efficiency via neural meta-optimization of experts. In particular, provided is a machine learning framework in which a meta-optimization neural network can learn to fuse a collection of experts to provide a predicted solution. Specifically, the meta-optimization neural network can learn to predict the output of a complex optimization process which optimizes over outputs from the collection of experts to produce an optimized output. In such fashion, the meta-optimization neural network can, after training, be used in place of the complex optimization process to produce a synthesized solution from the experts, leading to orders of magnitude faster and computationally more efficient prediction or problem solution.

Performance of complex optimization tasks with improved efficiency via neural meta-optimization of experts

Images of a plurality of users are captured concurrently with the plurality of users evincing a plurality of expressions. The images are captured using one or more eye tracking sensors implemented in one or more head mounted devices (HMDs) worn by the plurality of first users. A machine learnt algorithm is trained to infer labels indicative of expressions of the users in the images. A live image of a user is captured using an eye tracking sensor implemented in an HMD worn by the user. A label of an expression evinced by the user in the live image is inferred using the machine learnt algorithm that has been trained to predict labels indicative of expressions. The images of the users and the live image can be personalized by combining the images with personalization images of the users evincing a subset of the expressions.

Classifying facial expressions using eye-tracking cameras

A camera captures an image of a user wearing a head mounted device (HMD) that occludes a portion of the user's face. A three-dimensional (3-D) pose that indicates an orientation and a location of the user's face in a camera coordinate system is determined. A representation of the occluded portion of the user's face is determined based on a 3-D model of the user's face. The representation replaces a portion of the HMD in the image based on the 3-D pose of the user's face in the camera coordinate system. In some cases, the 3-D model of the user's face is selected from 3-D models of the user's face stored in a database that is indexed by eye gaze direction. Mixed reality images can be generated by combining virtual reality images, unoccluded portions of the user's face, and representations of an occluded portion of the user's face.
