Techniques for correcting linguistic training bias in training data
In automated assistant systems, a deep-learning model in form of a long short-term memory (LSTM) classifier is used for mapping questions to classes, with each class having a manually curated answer. A team of experts manually create the training data used to train this classifier. Relying on human curation often results in such linguistic training biases creeping into training data, since every individual has a specific style of writing natural language and uses some words in specific context only. Deep models end up learning these biases, instead of the core concept words of the target classes. In order to correct these biases, meaningful sentences are automatically generated using a generative model, and then used for training a classification model. For example, a variational autoencoder (VAE) is used as the generative model for generating novel sentences and a language model (LM) is utilized for selecting sentences based on likelihood. |

Fine-grained multi-tenant cache management
The embodiments herein describe a multi-tenant cache that implements fine-grained allocation of the entries within the cache. Each entry in the cache can be allocated to a particular tenant—i.e., fine-grained allocation—rather than having to assign all the entries in a way to a particular tenant. If the tenant does not currently need those entries (which can be tracked using counters), the entries can be invalidated (i.e., deallocated) and assigned to another tenant. Thus, fine-grained allocation provides a flexible allocation of entries in a hardware cache that permits an administrator to reserve any number of entries for a particular tenant, but also permit other tenants to use this bandwidth when the reserved entries are not currently needed by the tenant. |

Retention time based consistent hash ring
A retention-based consistent hash ring process defines each file name in the system to include its expiration date (or time) as a prefix or suffix that is stored and indexed as metadata. The process uses a virtual node to represent adjacent expiration days to create virtual nodes based on individual days of the week. Each physical node contains the same number of labeled virtual nodes, and the consistent hash ring process is used to move files with the same expiration day to different physical nodes by looking for next labeled virtual nodes on the hash ring. This provides a way to locate the virtual node storage location by specifying a file's expiration date as part of the key used in the hash ring process, and distributes files that may otherwise be assigned to the same physical node through a backup policy. |

Coordinate measuring machine and method for measuring coordinates of a workpiece
A coordinate measuring machine has a measurement head having a point measurement device which measures first coordinates of only a single point on the surface of a workpiece at a given time. An area measurement device records images of a reference surface. A displacement device displaces the measurement head and/or the workpiece such that they assume different relative positions with respect to one another. An evaluation device calculates a shift between images that the area measurement device has recorded of the reference surface at different times at different relative positions, with a stitching algorithm. Based on this, second coordinates of the measurement head, which are defined relative to the reference surface, are determined. By linking the first coordinates with the second coordinates, third coordinates are determined, which define the points on the surface of the workpiece measured by the point measurement device relative to the reference surface. |

Stray field robust out of shaft angle sensor and measurement system
The described techniques address the issues associated with conventional OoS sensor systems by mounting a magnetized ring onto a rotatable shaft for which an angular position is to be measured. Specific sensor configurations are disclosed regarding each magnetic sensor's position with respect to one another and each magnetic sensor's position with respect to the rotatable shaft. The described configurations provide a stray-field robust solution due to the specific magnetic sensor configurations such that, when stray fields are present, pairs of magnetic sensors are exposed to essentially the same stray field components, which thus cancel one another. Thus, the angle of the rotatable shaft as a function of the measured strength of the magnetic field components at any time instant can be calculated even in the present of stray magnetic fields. |
