Abstract: The present disclosure describes techniques for implementing automatic music audio transcription. A deep neural network model may be configured. The deep neural network model comprises a spectral cross-attention sub-model configured to project a spectral representation of each time step t, denoted as St, into a set of latent arrays at the time step t, denoted as θth, h representing an h-th iteration. The deep neutral network model comprises a plurality of latent transformers configured to perform self-attention on the set of latent arrays θth. The deep neural network model further comprises a set of temporal transformers configured to enable communications between any pairs of latent arrays θthat different time steps. Training data may be augmented by randomly mixing a plurality of types of datasets comprising a vocal dataset and an instrument dataset. The deep neural network model may be trained using the augmented training data.

Abstract: A hybrid transactional/analytical processing database includes an OLTP engine, OLAP engine, and shared storage including a mass storage device holding data of multiple tenants. The shared storage includes processing circuitry configured to implement a query executor configured to continuously monitor actual memory usage of the shared storage while the shared storage is responding to one or more queries from the OLTP engine or OLAP engine. Upon determining the actual memory usage of an operator evaluating the one or more of the queries from the OLTP engine or OLAP engine at the shared storage exceeds the preventative memory usage threshold but does not exceed the system memory usage threshold, the query executor is further configured to spill one or more fragments of query memory corresponding to the one or more queries to the mass storage device, without terminating the one or more queries.
