Abstract: Disclosed herein are an apparatus and method for self-supervised training of an end-to-end speech recognition model. The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program trains an end-to-end speech recognition model, including an encoder and a decoder, using untranscribed speech data. The program may add predetermined noise to the input signal of the end-to-end speech recognition model, and may calculate loss by reflecting a predetermined constraint based on the output of the encoder of the end-to-end speech recognition model.

Abstract: Disclosed herein are a dynamic segmentation apparatus and method for preventing a spread of a security threat. The dynamic segmentation apparatus includes one or more processors and execution memory for storing at least one program executed by the processors, wherein the program is configured to register feature information of a first device, which is a target for which a security threat is to be managed, generate a first segment from the feature information of the first device, receive security threat information from an external system, extract feature information of a second device, in which a security threat has occurred, from the security threat information, perform clustering on the feature information of the second device using at least one clustering algorithm, generate at least one segment set by identifying segments from clustering results, and determine a security threat segment based on an inclusion relationship between segments in the segment set.

Abstract: A communication method and an IoT device in a multi-MAC (Media Access Control)-operating environment. The communication method in the multi-MAC-operating environment, including synchronous MAC and asynchronous MAC, includes periodically transmitting, by the IoT device included in the multi-MAC-operating environment, a first message to a first device; determining, by the IoT device, whether to transmit a second message; transmitting, by the IoT device, a preamble packet to a second device, to which the second message is to be transmitted, when the second message is determined to be transmitted; and transmitting, by the IoT device, the second message to the second device.

Abstract: Disclosed herein are an apparatus for determining a device group to be isolated using similarity of features between devices and a method using the apparatus. The method includes generating device groups in consideration of respective features of all devices, generating a security threat device group based on devices in which a security threat has occurred, among all of the devices, calculating the cosine similarity between the security threat device group and all of the device groups, and determining at least one device group to be isolated, among all of the device groups, in consideration of the cosine similarity.
