[12:14] ToddSchneider: Ravi can you act as host. I'm not able to get microphone to work.

[12:17] RaviSharma: Todd yes i will be happy thanks

[12:19] ToddSchneider: Ravi, make sure to ask Sargur to send his slides to Ken (for posting on meeting page).

[12:23] John Sowa: Human-level explanations are always dialogs.

[12:24] John Sowa: A single Q/A is a very rare case. Follow-up questions and discussion are essential.

[12:28] John Sowa: The idea of first, second, and third wave implies that one replaces another.

[12:29] John Sowa: But it's more important to have a tool kit that includes *every* method in a mix & match system.

[12:31] RaviSharma1: John I agree that way one can choose the wave

[12:34] John Sowa: But how can an AI system learn what features are relevant?

[12:34] John Sowa: The most difficult task is to build the model.

[12:35] John Sowa: How can model building be automated?

[12:42] John Sowa: How could any such method be applied to a driverless car?

[12:43] John Sowa: When you're driving down the highway, you may have to make a decision in a split second. How do you derive the model and compute the probabilities?

[12:44] RaviSharma1: Q why log, also reason for Gausian distribution?

[12:44] John Sowa: I was thinking about the recent new about Seattle.

[12:45] John Sowa: one mile of telephone poles fell across a highway.

[12:45] John Sowa: The probability was o.ooooooooooooooooooooooooo1

[12:46] John Sowa: but when it happens, you have to deal with it.

[12:46] RaviSharma1: it would be detectable if size of poles are obstructions and AI should be able to brake the car

[12:48] janet singer: Ravi - yes, in that case the physical obstruction could be handled as such without explanation or understanding

[12:50] Ram D. Sriram: @Hari: What about the scalability of probabilistic network-based systems

[12:52] RaviSharma1: Janet Yes I was only thinking of vision and radar sensors response to any obstruction, similarly other sensors to rain snow skidding

[13:01] Ram D. Sriram: @Ravi: I seem to have problems speaking into the system as I am in another meeting right now. My question is "Are these probability-based models scalable?"

[13:18] BobbinTeegarden: @john: holistic metaphor?

[13:25] RaviSharma1: Sargur many thanks for a wonderful talk on Probabilistic XAI.
