Abstract: Systems and methods are provided performing autonomous tuning of a stringed instrument. Images of the stringed instrument are acquired by at least two cameras and processed to identify the location of a peg. A robotic peg actuator is then engaged to actuate rotation of a peg in order to rotate the peg to a tuned angular orientation, guided by feedback generated by processing acoustic signals recorded by an acoustic transducer while a string associated with the peg is agitated. In some example implementations, the cameras and peg actuator are rigidly mounted to a frame that is configured to support the stringed instrument during peg imaging and actuation. A robotic string actuator may be provided to facilitate vibration of the string during the tuning process. Multiple robotic peg actuators may be included for per-peg rotational actuation and/or a given peg actuator may be robotically translatable to actuate more than one peg.

Abstract: A disclosed method may include (1) mapping a block of shared memory to a plurality of processes running on a computing device, (2) determining, for a process within the plurality of processes, a local pointer that references a specific portion of the block of shared memory from a shared memory pointer that is shared across the plurality of processes by (A) identifying, within the shared memory pointer, a block number assigned to the block of shared memory and (B) identifying, within the shared memory pointer, an offset that corresponds to the specific portion of the block of shared memory relative to the process, and then (3) performing an operation on the specific portion of the block of shared memory based at least in part on the local pointer. Various other systems, methods, and computer-readable media are also disclosed.

Abstract: A disclosed method may include (1) maintaining a set of fleeting contexts that represent a lockless data structure at different moments in time, (2) determining an oldest context within the set of fleeting contexts, (3) identifying, within a discard list of the oldest context, a reference to an object stored in shared memory, and then (4) reclaiming, in the shared memory, a memory location occupied by the object whose reference was identified within the discard list of the oldest context. Various other apparatuses, systems, and methods are also disclosed.

Abstract: Identifying words to accurately describe, with a range of specificity, an image is provided. A vector space corresponding to the image is generated using a convolutional neural network to extract a hierarchy of features ranging from broad to specific from the image. Closest vocabulary ranging from broad to specific are identified for the image using Huffman coding on the vector space. Accurate words ranging from broad to specific are identified that describe the image based on vocabulary output of the Huffman coding on the vector space. The accurate words ranging from broad to specific describing the image are output.

Abstract: A microservices-management system intercepts a request for a cloud-based microservice sent by a microservices-architecture application. The system selects an optimal cloud-service provider from a group of candidate providers capable of delivering the microservice and then forwards the request to the optimal provider. The optimal provider is selected by drawing cognitive inferences from stored blockchain records that each describe a characteristic of a previous delivery of the requested service. Each record is generated by one of the candidate providers when delivering an instance of the microservice, regardless of whether the provider is in a trusted relationship with the application owner. The providers are barred by blockchain's intrinsic security features from altering or deleting previously stored blockchain records. Upon delivery of the service, the system compares the actual quality or cost of the delivery with predicted values in order to learn how to more effectively select optimal providers.
