After working for nearly a decade in sub-areas of artificial intelligence (robotics, temporal reasoning, constraint satisfaction and satisfiability), by 2006 I started to question the underlying idea that general artificial intelligence could arise by integrated all the sub-areas of AI into a unified Heath Robinson-type hybrid system. For the more neuroscience discovered about the one structure that we know exhibits general intelligence (i.e. the human neocortex) the less it looked like it implemented a hybrid set of independent specialised systems. Instead the neocortex showed itself to possess a remarkably uniform structure that seems to be performing the same basic function across its entire surface. And what has emerged from twenty-first century neuroscience is the idea that the neocortex is primarily engaged in making predictions about its own inputs and outputs – which has come to be known as the theory of predictive processing.
Taking heed of these developments, I formed the Cognitive Computing Unit at Griffith University as a centre of research where we could explore the computational implementation of predictive processsing and the following papers present the outcomes of this research. The primary focus has been the investigation and development of a particular implementation of predictive processing known as Hierarchical Temporal Memory, first proposed by Jeff Hawkins in the mid-2000s. This led to my own proposal of Hierarchical Temporal Intentionality (see ASSC 2014 below) which brings together the idea of predictive processing with the discoveries and insights of twentieth century phenomenology – connecting the brain science with our immediate experience of being conscious. This synthesis of science and consciousness is also a central theme in my new book The Questioning of Intelligence (see the Books page for more details, and The Being of Form below).
As with my work in constraint satisfaction, much of the actual coding and experimental evaluation reported in the papers below was performed by the PhD and Honours students I was supervising. And, as is usual, you can tell who had the greatest input into each paper by the order in which the author’s names are listed. Of these authors, I have been the primary PhD supervisor for Benjamin Cowley, Adam Kneller and Linda Main, and primary Honours supervisor for Andrew Srbic (for more detail on the pre-2010 papers co-authored with Jolon Faichney see the Handwriting Recognition page).
