What was your most difficult professional decision and why? What would you have chosen as your career if you hadn’t gone into robotics? It’s hard to pick one, but here are, briefly, three that are interesting: 1) I had to actively choose I think about that when I talk to K-12 students; whether to speak up against unfair treatment I try to tell them that it is fine to have a mean- when I was still pre-tenure and in a very under- dering path.

Since I got involved with socially assistive robotics, I truly love all my research projects: we are working with children with autism, with reducing pain in hospital patients, and ad- dressing anxiety, loneliness and isolation in the elderly.

How do you balance being involved in so many different aspects of the robotics and AI communities? With daily difficult choices: it’s an hourly strug- gle to focus on what is most important, set the rest aside, and then get back to enough of it but not all of it and, above all, to know what is in what category. I find that my family provides an anchoring balance that helps greatly with prioritizing.

Timothy Lee and Justin Svegliato, two Student SIGAI Scholars, cover The 50 Years of the ACM Turing Award Celebration, which con- vened in San Francisco last June. The semi- centennial celebration addressed the past, present, and future advancements of comput- ing, ranging from deep learning and ethics to augmented reality and quantum computing.

Artificial Intelligence is described by Neapolitan and Jiang(2012, p. 8) as ‘an intelligent entity that reasons in a changing, complex environment’, but this definition also applies to natural intelligence. Russell, Norvig, and Intelligence(1995) provide an overview of many definitions combining views on systems that think and act like humans and systems that think and act rational, but they do not present a clear definition of their own. For now, I adhere to the description Bryson, Kime, and Zrich(2011) provide. They state that a machine (or system) shows intelligent behaviour if it can select an action based Figure 1: Concepts of Responsible AI (based on on an observation in its environment. The (Dignum, 2016)) intervention of the autopilot that prevented the crash of the F-16 is an example of this ‘action selection’ (US Airforce, 2016).

I found that substantive empirical research on values related to Autonomous Weapons is lacking and it is unclear which moral values people, for example politicians, engineers, mil- itary and the general public, would want to be incorporated into the design of Autonomous Weapons. The Value-Sensitive Design could be used as a proven design approach to figure out which values are relevant for a responsible design of Autonomous Weapons (Friedman & Kahn Jr, 2003; van der Hoven & Mander- sHuits, 2009).

An example of this are drones that were initially designed for military purposes, but are now also used by civilians for filming events and even as background lights during the 2017 Su- per bowl half-time show. The value of safety is interpreted differently for military users that use drones in desolated regions compared to 300 drones flying in formation over a popu- lated area. The different context and usage of a drone will lead to a different interpretation of the safety value and could lead to more strict norms for flight safety which in turn could be Figure 3: Value hierarchy for Autonomous further specified in alternate design require- Weapons (based on Van de Poel(2013, p. 264)) ments for rotors and software for proximity alerts to name two examples.

64 RADIO AI - CALL FOR PARTICIPATION 2018

RADIO AI: An Important Invitation to AI Educators and Professionals to Talk About Your Work, Ideas and Thoughts On AI

Call for Participation: This invitation is extended across all the subfields of AI. The purpose of the RADIO AI project is to help educate the public and other professions about AI, with a crowd sourced collective of podcasts by people who work on AI. Submit podcasts in .mp3 or .wav by email to [email protected] See http://www.radioai.net for examples.

Some of the people talking the loudest about AI right now don’t actually work on AI. We hope to hear from many individuals who wish to counter fear of AI by educating the public with lighthearted informative podcasts. People who are passionate about their work in AI tend to see the good it can do to help society, the environment, healthcare, and all aspects of life. We hope you will share this vision with others. Our goal is to bring together the collective vision through short podcasts and create easy to understand informative lectures by the people who work in AI - academia, business, finance, healthcare, inventors, and programmers. The lectures can be as short as 3 minutes or as long as 10. Some of you might wish to do a series of podcasts.

Deadlines:

Intent to submit: Nov. 1, 2017

Notifications Due: Dec. 1, 2017

Draft podcasts due: Dec. 12, 2017

Final podcasts due: Jan. 12, 2017

Audience: Please gage the audience as either teenage or in another field of study that is non-technical.

Directions: Example podcasts are located on www.radioai.net All you need is some peace and quiet, a microphone and your inspired thinking.

Topics:

History of AI, Software agents, Robots, Machine learning, Fuzzy AI, Overview of AI, AI and Society, Human-Robot Interaction and Applications - Healthcare, Legal, Transportation, Energy, Environment, etc. All topics related to AI are welcome. Other - if you're working in this field and are aware of the social changes that will or already have been taking place, we welcome your insights for the public.

Travel/hotel: There is no travel or hotel reservation required.
