Gaining Insight into Quality Diversity [PDF]
Proceedings of the 2016 on Genetic and Evolutionary Computation Conference Companion, 2016 Recently there has been a growing movement of researchers that believes innovation and novelty creation, rather than pure optimization, are the true strengths of evolutionary algorithms relative to other forms of machine learning. This idea also provides one possible explanation for why evolutionary processes may exist in nervous systems on top of ...

Diversity-multiplexing gain tradeoff: A tool in algebra? [PDF]
2011 IEEE Information Theory Workshop, 2011 Since the invention of space-time coding numerous algebraic methods have been applied in code design. In particular algebraic number theory and central simple algebras have been on the forefront of the research. In this paper we are turning the table and asking whether information theory can be used as a tool in algebra.

Subblocks Set Design Aided Orthogonal Frequency Division Multiplexing With All Index Modulation
IEEE Access, 2019 In recent years, OFDM with index modulation (OFDM-IM) has become a potential technique due to its improvement of diversity gain. In typical OFDM-IM schemes, incoming information bits are divided into two parts, symbols bits, and index bits.
