Photonic artificial intelligence: Reservoir computing and decision making based on complex photonics

Abstract:
We overview recent technologies of photonic artificial intelligence using reservoir computing and decision making. We propose photonic integrated circuits for reservoir computing using semiconductor lasers with optical feedback, and construct multiple reservoirs for performance improvement of chaotic-time series prediction. We also demonstrate several decision-making schemes for solving the multi-armed bandit problem using optical spatio-temporal dynamics and mode competition dynamics of semiconductor lasers.

Prof. Sungtek Kahng (Incheon Nat셪 Univ., Republic of Korea)

Automated solution finding approaches based on stochastic optimization methods in the A.I.-inundated society

Abstract:
This tutorial deals with stochastic automatic optimization methods known as programing-based optimization approaches such as Evolutionary Strategy, Genetic Algorithm, Particle Swarm Optimization whose relatives are Marine Predator Algorithm and Weed Colonization from the standpoints of principles and the applications to Engineering problems. These methods will be mentioned by being compared to ANN, Machine Learning, and their up-to-date optimization techniques.
