On 8th February 2023 at 10:30h the CTTC will host the seminar “On Autoencoder-Based Error Correcting Codes”. In this seminar Vukan Ninkovic, PhD student will present:
Abstract
Most of today’s communication systems are designed to target reliable message recovery after receiving the entire encoded message (codeword). However, in many practical scenarios, the transmission process may be interrupted before receiving the complete codeword. We propose a novel rateless autoencoder (AE)-based code design suitable for decoding the transmitted message before the noisy codeword is fully received. Using particular dropout strategies applied during the training process, rateless AE codes allow to tradeoff between decoding delay and reliability, providing a graceful degradation of the latter with each additionally received codeword symbol. Also, we will present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed approach, based on a generalization of an autoencoder loss function, provides a versatile framework for the design of message-wise and bit-wise UEP codes.
