  • Publication number: 20190355471
    Abstract: A control method for a reinforcement learning system includes following operations. The reinforcement learning system obtains training data relating to an interaction system. The interaction system interacts with a reinforcement learning agent. A neural network model is utilized by the reinforcement learning agent for selecting sequential actions from a set of candidate actions. The neural network model is trained to maximize cumulative rewards collected by the reinforcement learning agent in response to the sequential actions. During training of the neural network model, auxiliary rewards of the cumulative rewards are provided to the reinforcement learning agent according to a comparison between symptom inquiry actions of the sequential actions and diagnosed symptoms in the training data.

  • Publication number: 20190334524
    Abstract: Systems, apparatuses, and methods for efficiently performing operations system are disclosed. A computing system uses a memory for storing data, and one or more processing units. The memory includes multiple rows for storing the data with each intersection of a row and a column being a memory bit cell. The memory processes operations. For particular operations, the two or more operands are accessed simultaneously for generating a result without being read out and stored. Two indications are generated specifying at least a first row and a second row targeted by the operation. The memory generates a result by performing the operation for each of the one or more cells in the first row a stored value with a respective stored value in the one or more cells in the second row.

    Abstract: A cap may include a top and a sidewall depending from the top. A plug may also extend from the top, spaced from the sidewall. Threads are formed either on an internal surface of the sidewall, i.e., generally facing the plug, or on an external surface of the plug, i.e., generally facing the sidewall. The spacing between the sidewall and the plug generally defines a receptacle configured for receiving an open end of a container. The sidewall and the plug may be angled relative to each other, such that the receptacle has a cross-section that is generally V-shaped.
