    1.10  To attack the action recognition problem, I developed a computational
    1.11  model of empathy (=EMPATH=) which allows me to recognize actions using
    1.12  simple, embodied representations of actions (which require rich

    1.22  In order to build this empathic, action-recognizing system, I created
    1.23  a program called =CORTEX=, which is a complete platform for embodied
    1.24  AI research. It provides multiple senses for simulated creatures,
