It is our great pleasure to introduce the proceedings of the 31st Australasian Joint Conference on Artificial Intelligence Workshops (AIW'18). The Conference, hosted by Victoria University of Wellington, New Zealand in December 2018, has been an annual event dedicated to fostering research communication and collaboration among Australasian AI community since inception. In 2018, three workshops were accepted to be held in conjunction with the Conference. Due to logistic reasons, only one of them, the 5th Workshop on Machine Learning for Sensory Data Analytics (MLSDA'18), proceeded with organisation and was successfully held on 11 December. |
