    摘要： An encoding device and a decoding device use linear and nonlinear codes for encoding and decoding system data for a storage device. The encoding device includes a linear encoder for encoding first data to generate encoded data and a nonlinear transformer for transforming the encoded data with second data to generate output data. The first data includes data on a physical address corresponding to a logical address. The second data includes the logical address and a timestamp value indicating a version of map data mapping between the logical address and the physical address.

    摘要： A method, apparatus, and computer program product for improved pseudo-random number generation are provided. An example method includes receiving, by a computing device, a request for a pseudo-random number, selecting, by extraction circuitry of the computing device, a first parameter from a server parameter dataset, and obtaining a first value for the first parameter. The method further includes selecting, by the extraction circuitry, a second parameter, and obtaining a second value for the second parameter. The method includes generating, by transformation circuitry, the pseudo-random number based on the first value and the second value.

    摘要： A method for protecting a machine learning model is provided. In the method, a first machine learning model is trained, and a plurality of machine learning models derived from the first machine learning model is trained. Each of the plurality of machine learning models may be different from the first machine learning model. During inference operation, a first input sample is provided to the first machine learning model and to each of the plurality of machine learning models. The first machine learning model generates a first output and the plurality of machine learning models generates a plurality of second outputs. The plurality of second outputs are aggregated to determine a final output. The final output and the first output are classified to determine if the first input sample is an adversarial input. If it is adversarial input, a randomly generated output is provided instead of the first output.

    摘要： An electronic gaming device is described. The device is configured to receive an input requesting play of a feature game, initiate the feature game wherein the feature game includes a plurality of reels, and randomly determine, based upon a first output from a random number generator (RNG), at least one instant feature. The device is also configured to determine a table of symbols associated with the at least one instant feature and populate at least one reel position of at least one reel with at least one symbol from the table of symbols wherein the at least one symbol is associated with the at least one instant feature. The device is further configured to, based upon a second output from the RNG, determine an outcome for the feature game and control display of the feature game including presentation of the at least one instant feature.

    摘要： A gaming device is provided. The gaming device may be configured to, determine that at least a first base prize symbol is displayed in a first matrix position of a matrix of a game display, the first base prize symbol being associated with a first prize amount, cause the game display to display, in the first matrix position, a first transparent prize symbol, the first transparent prize symbol being associated with the first prize amount, in response to a bonus game instance, generate at least one special symbol in the matrix, determine that the at least one special symbol is displayed in the first matrix position that includes the first transparent prize symbol, and display a second transparent prize symbol in the first matrix position, the second transparent prize symbol being associated with a second prize amount greater than the first prize amount.

    摘要： A memory system connectable to a host device includes a nonvolatile memory, a first circuit configured to generate a sequence of random number bits, and a processor configured to instruct the circuit to generate a sequence of random number bits having a first length, calculate a first value indicating randomness of the sequence, determine whether the first value exceeds a threshold value, upon determining that the first value exceeds the threshold value, generate a pseudo random number using the sequence, upon determining that the first value does not exceed the threshold value, instruct the first circuit to generate another sequence of random number bits having a second length greater than the first length, and generate a pseudo random number using said another sequence, and write or read data to or from the nonvolatile memory using the generated pseudo random number.

    摘要： In an embodiment, a processor may include an execution engine to execute a plurality of instructions, a memory to store a tagged data structure comprising a plurality of entries, and an eviction circuit. The eviction circuit may be to: generate a pseudo-random number responsive to an eviction request for the tagged data structure; in response to a determination that the pseudo-random number is outside of a valid eviction range for the plurality of entries, generate an alternative identifier by rotating through the valid eviction range, the valid eviction range comprising a range of numbers that are valid to identify victim entries of the tagged data structure; and evict a victim entry from the tagged data structure, the victim entry associated with the alternative identifier. Other embodiments are described and claimed.
