Information processing device, information processing method, and information processing program

An information processing device performs control to record deletion information indicating that an object with a designated object ID has been deleted, on a recording medium, in a case where a specific object ID is designated and an instruction to delete the object is input, for a magnetic tape on which an object that includes data and metadata related to the data and that is assigned an object ID as identification information is recorded, the object being assigned an object ID in a case where the object is updated different from an object ID of the object before the update.

Test data may be generated by classifying a plurality of medical records of patients into a plurality of groups, based on at least an execution characteristic of a processing program that processes the medical records, and generating test data including at least a part of the plurality of medical records based on proportions of the number of the medical records classified into the plurality of groups.

Generation of test data for a data platform

Provided is a method for storing at least a portion of data registered in a blockchain in each of a plurality of node apparatuses, including selection of selecting whether to store data included in a block in one node apparatus among the plurality of node apparatuses, according to a characteristic of the one node apparatus; and data storage of storing at least a portion of the data included in the block in the one node apparatus, according to a result of the selection.

Blockchain technology

A method, computer system, and a computer program product for digital image recognition determination using a learned model is provided. The present invention may include acquiring a first determination result by making a determination concerning first data, using a first learned model. The present invention may include selecting a partial region of the first data. The present invention may then include generating second data obtained by applying a first alteration process to the partial region. The present invention may also include acquiring a second determination result by making a determination concerning the second data, using a second learned model. The present invention may lastly include obtaining a final determination result based on the first determination result and the second determination result.

Determination using learned model

An event transition model for producing test data may be generated from a plurality of event records, each event record including an event time of an instance, wherein the event transition model includes a plurality of states, each state corresponding to one or more instances of the plurality of event records, event transition probabilities between states, and event transition interval times between states.

Generation of event transition model from event records

There is provided a tape recording apparatus system capable of improving writing performance and maintaining tape recording density, for a multiple data writing request accompanied by a lot of synchronization requests from a host. The system is a tape storage system including two or more tape drives each of which has a tape mounted thereon and is provided with a buffer divided in fixed-length segments, and connected to a host that sends multiple data and a synchronization request at a predetermined timing to these tape drives. This tape recording system is provided with: a tape drive connected to the host, receiving the multiple data sent from the host, and, when the segment of the buffer is accumulated and filled with data, writing the accumulated data onto a tape; and another tape drive connected to the tape drive, receiving the multiple data sent from the host via the tape drive, and dumping a predetermined number of data accumulated in the segments onto a tape at a timing of receiving the synchronization request.

Tape storage system including at least two tape storage apparatuses for improved writing of data to be synchronized

Reducing time required to write a file to tape is provided. Synchronous processing is performed in a file system implementing a Linear Tape File System (LTFS) file format, wherein the synchronous processing includes writing, to a tape medium of a tape cartridge, index information and one or more files. A type of the synchronous processing is determined, wherein the type is either an index-MAM sync type or an index-only sync type. Updated information is stored to a media auxiliary memory of the tape cartridge in response to determining that the synchronous processing is of the index-MAM sync type.

Reduction in time required to write file to tape

Managing metadata added to a file, a directory, or a symbolic link is provided. One or more pieces of metadata of a movement target are obtained. The movement target is at least one of a file, a directory, and a symbolic link. The movement target is to be moved from one file system to another file system within a plurality of file systems. Whether the one or more pieces of metadata are migratable to the other file system is determined based, at least in part, on metadata stored in the other file system. The one or more pieces of metadata are processed by (i) migrating a first piece of metadata that is determined to be migratable to the other file system and (ii) leaving a second piece of metadata in the one file system, wherein the second piece of metadata is determined to be non-migratable.

Information management

A method, computer system, and a computer program product for predicting a variation of sequential blood glucose levels by using deep learning is provided. The present invention may include training a predictor associated with a user by using a deep learning network. The present invention may further include predicting a plurality of sequential blood glucose levels by the trained predictor based on at least one meal image, at least one time-period, and at least one set of data associated with a plurality of blood glucose levels of the user.

Estimating sequential blood-sugar levels using images of meals

In a mechanism for deleting blocks from a blockchain, a retention period (T), a minimum number of blocks (L), and a hash of the oldest block are defined. A participant node creates the new block including a block header. The participant node determines whether a timestamp in an oldest block in the blockchain is older than a current time plus T, and whether a current number of blocks in the blockchain is greater than or equal to L. When both are true, the participant node deletes an oldest block in the blockchain. The participant node adds a hash of an oldest remaining block and an original number of blocks of the blockchain to the block header of the new block. The participant node broadcasts a message announcing the new block to remaining participant nodes of the plurality of participant nodes.

Deletion of blocks in a blockchain

A storage system receives one or more records from a host system. The records are compressed in a first compression format that is native to the host system. The storage system identifies an incompatibility between the first compression format and a first operation of the storage system. In response to the identified incompatibility, the storage system decompresses the received records. The decompression is based on the first compression format. The storage system compresses the decompressed records in a second compression format. The storage system stores the secondarily compressed records onto a storage medium.
