  • Patent number: 12014603
    Abstract: A gaming device comprises a display, a processor, and a memory storing (a) reel strip data defining a set of reel strips, each reel of the set of reel strips comprising special symbols and regular symbols; and (b) instructions. The reel strips are used to select symbols to populate positions of a playing field shown on the display. When two or more of the same special symbols occupy adjacent positions of the playing field, they may merge into a single position occupied by one of the special symbols in question. If three or more special symbols are adjacent, all merge into a single position and a higher-value special symbol. This merge may be signaled by a graphic such as an animation or image, a sound, a light, a vibration, or other audiovisual or haptic indicator. The higher-value special symbol thus replaces one of the adjacent special symbols while the rest are removed or disappear.

  • Publication number: 20230289604
    Abstract: Aspects of the present disclosure provide systems, methods, and computer-readable storage media that support security-aware compression of machine learning (ML) and/or artificial intelligence (AI) models, such as for use by edge computing systems. Aspects described herein leverage cybersecurity threat models, particularly models of ML/AI-based threats, during iterative pruning to improve security of compressed ML models. To illustrate, iterative pruning may be performed on a pre-trained ML model until stop criteria are satisfied. This iterative pruning may include pruning an input ML model based on pruning heuristic(s) to generate a candidate ML model, testing the candidate ML model based on attack model(s) to generate risk assessment metrics, and updating the heuristic(s) based on the risk assessment metrics. If the risk assessment metrics fail to satisfy the stop criteria, the candidate ML model may be provided as input to a next iteration of the iterative pruning.
