Abstract: In-flight operations in an inbound data path from a source memory to a convolution hardware circuit increase computational throughput when performing convolution calculations, such as pooling and element-wise operations. Various operations may be performed in-line within an outbound data path to a target memory. Advantageously, this drastically reduces extraneous memory access and associated read-write operations, thereby, significantly reducing overall power consumption in a computing system.

Abstract: A method for stabilizing disrupted neural signals received by a brain-computer interface (BCI), where a translation model is trained on a clean and disrupted dataset and is used to translate a disrupted signal to a clean signal. The clean dataset is based on the data that is received the same day the BCI is calibrated and the disrupted dataset is based on data received the same day that the model is trained. Based on the variation in daily signal disruption, the training model is retrained each day and a new translation model is applied to a disrupted dataset.

Abstract: Storage-efficient, low-cost systems and methods provide embedded systems with the ability to dynamically perform on-device learning to modify or customize a trained model to improve computing and detection accuracy in small-scale devices. In certain embodiments, this is accomplished by repurposing storage elements from inference to training and performing partial back-propagation in embedded devices in the final layers of an existing network. In various embodiments replacing weights in final layers, while using hardware components to iteratively performing forward-propagation calculation, advantageously, reduces the need to store intermediate results, thus, allowing for on-device training without significantly increasing hardware requirements or requiring excessive computational memory resources when compared to conventional machine learning methods.
