Abstract: Technologies are disclosed for providing visual feedback during touch-based operations on user interface (“UI”) elements. Through implementations of the disclosed technologies, visual feedback can be provided to users during certain touch-based operations on UI elements presented by virtual reality (“VR”) devices. The visual feedback can provide confirmation to users that certain operations on UI elements were performed successfully. The visual feedback provided by the disclosed technologies can make it easier for users to select a UI element, to understand that actions taken to select a UI element were successful, and to successfully perform operations on UI elements once they have been selected. These benefits can reduce the number of times users need to attempt certain operations on UI elements. This, in turn, can reduce the utilization of computing resources, such as memory and processor cycles, by devices implementing the disclosed technologies.

Abstract: Using a graphical user interface (GUI), a user is guided to generate a logical graph that represents how real data is generated in a situation. The situation is simulated using an artificial intelligence (AI) model a number of times by having the AI model choose paths through the logical graph to generate synthetic data that is representative of the real data. The AI model may also use a reward table that the user is guided to generate via the GUI to execute the simulation, wherein the reward table incentivizes certain paths of the logical graph, and agents of the AI model are trained using the values of this reward table. This synthetic data generated via the AI model can be used for training other AI models.
