Abstract: Techniques described herein relate to automated management of database accounts within cloud environments and other large-scale computing environments. In such environments, an identity provider service for an organization may maintain the various roles for the users associated with the organization. As described herein, a database account synchronization system may synchronize the user accounts within the database systems of the organization based on the corresponding roles stored within the identity provider. In some examples, the database account synchronization system may periodically query the identity provider to retrieve user-role mappings for the various user groups defined by the identity provider. For each user group, the database account synchronization system may query the organization database systems, compare the user permissions of each database to the user-role mappings within the identity provider, and update the database user accounts to synchronize the databases with the identity provider.

Abstract: Neural Architecture Search (NAS) is a laborious process. Prior work on automated NAS targets mainly on improving accuracy but lacked consideration of computational resource use. Presented herein are embodiments of a Resource-Efficient Neural Architect (RENA), an efficient resource-constrained NAS using reinforcement learning with network embedding. RENA embodiments use a policy network to process the network embeddings to generate new configurations. Example demonstrates of RENA embodiments on image recognition and keyword spotting (KWS) problems are also presented herein. RENA embodiments can find novel architectures that achieve high performance even with tight resource constraints. For the CIFAR10 dataset, the tested embodiment achieved 2.95% test error when compute intensity is greater than 100 FLOPs/byte, and 3.87% test error when model size was less than 3M parameters.

Abstract: Presented herein are embodiments of a prefix-to-prefix framework for simultaneous translation that implicitly learns to anticipates in a single translation. Within these frameworks are effective “wait-k” policy model embodiments that may be trained to generate a target sentence concurrently with a source sentence but lag behind by a predefined number of words. Embodiments of the prefix-to-prefix framework achieve low latency and better quality when compared to full-sentence translation in four directions: Chinese?English and German?English. Also presented herein is a novel latency metric that addresses deficiencies of previous latency metrics.

Abstract: Described herein are systems and methods to identify and address sources of bias in an end-to-end speech model. In one or more embodiments, the end-to-end model may be a recurrent neural network with two 2D-convolutional input layers, followed by multiple bidirectional recurrent layers and one fully connected layer before a softmax layer. In one or more embodiments, the network is trained end-to-end using the CTC loss function to directly predict sequences of characters from log spectrograms of audio. With optimized recurrent layers and training together with alignment information, some unwanted bias induced by using purely forward only recurrences may be removed in a deployed model.

Abstract: Described herein are systems and methods for automatic unit selection and target decomposition for sequence labelling. Embodiments include a new loss function called Gram-Connectionist Temporal Classification (CTC) loss that extend the popular CTC loss function criterion to alleviate prior limitations. While preserving the advantages of CTC, Gram-CTC automatically learns the best set of basic units (grams), as well as the most suitable decomposition of target sequences. Unlike CTC, embodiments of Gram-CTC allow a model to output variable number of characters at each time step, which enables the model to capture longer term dependency and improves the computational efficiency. It is also demonstrated that embodiments of Gram-CTC improve CTC in terms of both performance and efficiency on the large vocabulary speech recognition task at multiple scales of data, and that systems that employ an embodiment of Gram-CTC can outperform the state-of-the-art on a standard speech benchmark.

Abstract: A system and method for 3D design includes defining a three-dimensional virtual interaction space visualized with a 3D camera system operable to generate three-dimensional coordinate data corresponding to physical objects within the interaction space. A physical gesture of the user within the interaction space is interpreted according to pre-determined rules, the physical gesture including a movement of a physical object. A virtual shape is generated or manipulated in response to the interpretation of the physical gesture, the virtual shape residing virtually within the interaction space. A representation of the virtual 3D shape is interactively displayed during the physical gesture.
