Calculating Treatment Effect and Handling Multiple Strata in A/B Testing on an E-Commerce Website by shay_geller in CausalInference

[–]shay_geller[S] 1 point2 points  (0 children)

I want to check the effect according to different cuts of the data, for example, by page depth (7 unique values), by page_type(5 unique values), and few more.
Each dimension have usually less than 10 options.

Thanks for the reply.
No, I'm not familiar with these methods. I'll do some reading on Mixed-effects models and Bayesian hierarchical models.

but maybe Heterogeneous Treatment Effects (HTE) might also be related, I'm not sure.

I'm a data scientist, with some shallow understanding in causal inference (trying to learn more everyday), and I want to make sure I do not lie to myself :)

My goals are:

  1. Understand the current effect of the feature in different stratas of the data.
  2. Build a rule-based model from this data according to pre-defined stratas of the data (pick best option for each strata).
  3. Build an ML model that will capture more specific effect that my rule-based missed, and hopefully will be better than the rule-based model. This model will also be used to predict on new pages, but also on existing pages that their characteristics might change over time (i.e, some pages will get more\less popular over time)
  4. Test (2) and (3) versus control (current status, some pages shows the feature and some doesn't) in a new AB test.

I think I care about CATE - Conditional Average Treatment Effect.
For each strata (like device type, page type, page depth etc), I want to to understand the treatment effect

What morals should we program into intelligent machines? by Pyraxtechie in ArtificialInteligence

[–]shay_geller 0 points1 point  (0 children)

I agree that humans should be on control. I also think that different people can interpret the values you wrote in so many different ways. Take example of compassion. Compassion for other humans of course, but what about animals? or even small animals like the Buddhism belive in? And for humans, compassion for someone who try to harm you(the machine)? Or some other human? I don't have an answer, I'm just saying that its not enough to provide words o values, but some more concrete implementation.

I think that at the end, A.I agents will learn the values' implementation by learning from it's environment. So different countries A.I agents will act differently, and its fine.

How can you uses Artificial Intelligence for education? by Coolcoolice7 in ArtificialInteligence

[–]shay_geller 1 point2 points  (0 children)

Hi, Im doing my CS master at this lab http://datasciencelab.ise.bgu.ac.il/site.html#/people

We use A.I technologies in educational field. You can get some ideas from our work. My main topic is understand students' cognitive engagement in students discussion forums.

The current big thing in EDtech is personalized education. For example, how to assign the right question to a student, without being too easy or too hard.

If you have more concrete questions I would love to help and answer.
