Abstract: Methods and devices for treatment of metal surfaces by means of electrically active solid particles that include a step of contact of the solid particles with the electrode of an electric source, a step of shooting the particles towards the metal surface to be treated and a step of transmission of electric charge of the particles on the metal surface to be treated. The transmission of the electricity between the electric source and the metal surface during the step of shooting preferably is by net charge of the particles or by electric conductivity by contact or by electric conductivity by means of voltaic arches. The current applied to the electrode is preferably a DC or a current that contains positive sections and negative sections.

Abstract: Systems and methods are disclosed method for controlling instantaneous current changes in parallel processors with arrays of parallel computing elements, such as neural processors. An exemplary method comprises monitoring the array of computing elements and determining a transition from a first activity level of the array to a second activity level of the array, such as an idle-to-active or active-to-idle transition. Once a transition is determined, the array is selectively controlled to minimize the instantaneous current change from the transition from the first activity level to the second activity level.

Abstract: A machine learning model for reinforcement learning uses parameterized families of Markov decision processes (MDP) with latent variables. The system uses latent variables to improve ability of models to transfer knowledge and generalize to new tasks. Accordingly, trained machine learning based models are able to work in unseen environments or combinations of conditions/factors that the machine learning model was never trained on. For example, robots or self-driving vehicles based on the machine learning based models are robust to changing goals and are able to adapt to novel reward functions or tasks flexibly while being able to transfer knowledge about environments and agents to new tasks.

Abstract: Systems and methods for customizing business applications based upon user intent scores is described. A machine learning model trained to specifically predict when a user is likely to engage in a specific activity while interacting with the business application may be trained using data regarding prior interactions between a business application and a plurality of users. The machine learning model may thereafter provide a probability score for a particular user, the probability score indicating the likelihood that the user will engage in the specific activity for which the model has been trained to predict. The probability may be combined with a business value factor to produce a user intent score indicating the relative value of the user engaging in the specific activity.

Abstract: An apparatus for hardware acceleration for use in operating a computational network is configured for determining that a loop structure including one or more loops is to be executed by a first processor. Each of the one or more loops includes a set of operations. The loop structure may be configured as a nested loop, a cascaded or a combination of the two. A second processor may be configured to decouple overhead operations of the loop structure from compute operations of the loop structure. The apparatus accelerates processing of the loop structure by simultaneously processing the overhead operations using the second processor separately from processing the compute operations based on the configuration to operate the computational network.
