Multidrop data transfer
Multi-drop communications channels can have significantly deep notches in their frequency response causing a corresponding limitation of the effective data transmission rate.

Training text recognition systems
In implementations of recognizing text in images, text recognition systems are trained using noisy images that have nuisance factors applied, and corresponding clean images (e.g., without nuisance factors). Clean images serve as supervision at both feature and pixel levels, so that text recognition systems are trained to be feature invariant (e.g., by requiring features extracted from a noisy image to match features extracted from a clean image), and feature complete (e.g., by requiring that features extracted from a noisy image be sufficient to generate a clean image). Accordingly, text recognition systems generalize to text not included in training images, and are robust to nuisance factors. Furthermore, since clean images are provided as supervision at feature and pixel levels, training requires fewer training images than text recognition systems that are not trained with a supervisory clean image, thus saving time and resources. |

A device compresses a mapping table in a flash translation layer of a SSD. The mapping table includes mappings between Logical Page Numbers (LPNs) and Physical Page Numbers (PPNs). A base PPN table stores at least one entry including a base PPN common to multiple LPNs. A PPN offset table stores an offset for each mapping. A set of hash functions are duplicated for each entry in the base PPN table. A bit extension unit adds bits to the respective offset in the PPN offset table to provide an extended offset bit. A hash calculator calculates a hash value using the base PPN and one of the hash functions corresponding to the base PPN. An exclusive OR unit outputs a new PNN for each of different LPNs, including the multiple LPNs, by applying an exclusive OR operation to the hash value and the extended offset bit. |

The system uses a neural network including a first subnetwork sequentially connected with a sequence of second subnetworks for each of the future instance of time such that an output of one subnetwork is an input to a subsequent subnetwork. The first subnetwork accepts the current time-series data and the current setpoints of operation of the machine. Each of the second subnetworks accepts the output of a preceding subnetwork, an internal state of the preceding subnetwork, and a future setpoint for a corresponding future instance of time. Each of the second subnetworks outputs an individual prediction of each fault of a plurality of faults at the corresponding future instance of time. |
