Abstract: A method, computer system and computer program product is presented for providing a self-supervised speech representation. In one embodiment, audio input is received including speech utterances. A label sequence is generated from these speech utterances by a teacher label generator. A speech representation is generated of a partially masked version of the speech utterance using a speech representation network.

Abstract: This application discloses a method for identifying a source address of a packet and an apparatus, and pertains to the field of network security. A protecting device intercepts a packet whose destination address is an IP address of a protected device, where the protected device provides a service according to the QUIC protocol. The protecting device sends a retry packet to a source address of the packet in response to that the packet is an initial packet. The protecting device identifies the source address of the packet as an attack source address if the protecting device receives no response packet corresponding to the retry packet. The protecting device determines the source address of the intercepted initial packet to identify an attack source address used by an attacker, and subsequently prevents only packets from the attack source address from being sent to the protected device.

Abstract: Provided are a computer program product, system, and method for training a pose estimation model to determine anatomy keypoints in images. A teacher network, implementing machine learning, processes images representing anatomies to produce heatmaps representing keypoints of the anatomies.

A pose estimation model, implementing machine learning, is trained to process the images to output predicted heatmaps to minimize a loss function of the output predicted heatmaps from the pose estimation model and the mixed heatmaps.
