Thank you Steve, the best overview that I have seen till now, it is a big challenge to keep it at a high level. Awesomely done.

Assuming I have 200 loan applicants and split it into 70% Training and 30% Test, how do I then get predictions for the applicants that belong to the 70% Training?

Many thanks, Steve, for a truly useful overview of this burgeoning field, and to AllAnalytics for hosting the presentation.

Can you explain the QC process a bit more and 'averaging' the model?

which domain will be most impacted by AI in the next 5-10 years?

Are there any guidelines on data size for training?

Hello, new to this. Is there a way to get a hold of the presentation?

Steve is giving some good takeaways - tradeoffs is a great viewpoint in capturing the value from ML.

Given the "house built on a hill" example, where the model may incorrectly predict that being built on a hill might be worth more than the square footage--isn't that the type of insight we are looking to gain from this technology?  For the computer to identify correlations among the data that we currently discount or are otherwise oblivious to?  I can see a correlation, for example, of houses built on hills to provide extra value due to vistas, flood deterrent, etc. (I realize it was just an example, but the point seems to be to have the machines learn new correlations for us, right?)

Evaluation metrics is a great way to look at validity. There was a time where vanity metrics was what was presented. ML adds another layer, and better nuance for decisions because of the nuance in the model results.

And the idea of converting data to numbers.

Like the explanation on ordinal - the importance of directional information - this slide is helpful against techniques I can imagine in R (or Python - have to shout out to both languages)

zpatwa how about now? Are you hearing ok?

The typeface on the presentation is so small I can't read?

Good timing Robert - seeing a lot of interest on images in analysis because of geotagging and correlating data in R & Python.

I am working on the use of imagery based artificial neural networks to produce a natural language processor with faster throughput, and higher resolution.

 

Sounds like a great talk! Can't wait to hear it!
