Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating differential privacy noise and applying the noise to data. In one aspect, a method includes obtaining a first binomial distribution parameter. Target differential privacy parameters representing a target level of differential privacy are obtained. The target differential privacy parameters include a first target differential privacy parameter representing a privacy metric that controls a level of privacy of data. For each value of multiple values of a second binomial distribution parameter, an actual value of a first actual differential privacy parameter that represents an actual privacy metric is determined based on the value of the second binomial distribution parameter. A determination is made whether the actual value of the first differential privacy parameter satisfies the first target differential privacy parameter.

Abstract: Subword tokenization is provided. The method comprises receiving a text document comprising n bytes and specifying a maximum token width of L bytes. An initial vocabulary of tokens is defined, wherein the tokens comprise a number of different n-grams of L or less bytes. The document is tokenized with the fewest number of tokens from the vocabulary according to a minimum total weight through a directed acyclic graph comprising nodes that represent intervals between the bytes in the document and edges that represent potential tokens from the vocabulary appearing in text of the document. Natural language processing is then performed on the text document according to the tokenization.

Abstract: A memory access request is initiated by a first peripheral device. The memory access request includes a virtual address.

The memory access request is transmitted using the identifier of the BAR to a second peripheral device.

Abstract: An ASDGS (Artificially Spiked Data Generation System) may comprise computing and mechanical systems for using a single class of data to generate artificially “spiked” data of a second class. To generate each spiked image, the ASDGS may randomly select a clean image an augmentation object (“AO”) from an object library, shape library, and/or hair library. The ASDGS may use a texture library to add or change the texture of the AO. The ASDGS may adjust the lighting and coloring of the AO to be similar to the clean image, and may then add the AO to the clean image to generate a spiked image.

Abstract: Systems and methods are provided for adjusting a fluid dispenser for depositing drops of formable material. According to embodiments, a system obtains an image of a substrate including a film formed on the substrate by curing the formable material deposited by a first dispenser and a second dispenser.

Adjustments based on the intensity values are made to change a drop volume and a drop density for nozzles of the first dispenser and nozzles of the second dispenser.

Abstract: Disclosed in some examples are improvements to memory controllers on distributed memory systems that include a fine-grained data mover component that offloads management of memory commands accessing multiple smaller values to the memory controller. The fine-grained data mover (FGDM) may provide low host processing overhead that enables performance improvements for small task offloads. Work requests (“data mover calls”) may be sent by hosts to the FGDM without OS system calls. The FGDM is a virtually addressed data movement engine architected to transfer data at high transfer rates even during situations where the host has many small data movement requests and where the source and/or destination addresses are not memory controller friendly.

Abstract: Disclosed in some examples are methods, systems, devices, and architectures which provide for techniques for memory device and memory fabric redundancy within distributed memory systems. In some examples, two memory devices are paired and each stores a same set of data such that writes to the memory devices are duplicated and reads may be satisfied from either device. In some examples, a memory processing unit (MPU) may be incorporated into the memory architecture to support these paired memory devices. The MPU may be placed between the host and a multi-planed memory fabric which connects to multi-ported CXL memory devices. In some examples, the MPU may also enable the use of alternative fabric links. That is, if a memory fabric link between the MPU and a memory device is unavailable, an alternative link may be utilized to restore connectivity to a memory device.
