"The project has been valuable in helping to demonstrate the proof of concept of developing a Severe System Pressure indicator. It has helped to give us an idea of what an approach may look like, and what may be achievable in terms of the kind of accuracy we could expect."

really nicely done. thanks
Beautiful voice and manner of speech
This is Gold! The best video explaining hierarchical bayesian models, it addresses many of the question I had, none of the other videos out there get to this level of details. it makes me feel more confident about using these models
Interesting tutorial
Great present. As far as i know, both uplift tree and T-learner are part of Potential Outcome Framework Model that predict CATE/ATE to know about the casual relationship.
Excellent explanation...Thank you!
Very nice, thanks a lot for the talk. Very well explained and easy to follow!
Very good explanations . Seen a lot of videos but your presentation is very understandable . Thanks
great one, currently looking for overlap between same treatment used for different diseases, this one looks very helpful to approach for synthesize
50:20 Make sure you know when to use variational inference instead of MCMC. (usually when working with large datasets)
What a great application of data science!
hands down the best explanation for hierarchical modelling on youtube, especially with the graph visualising the effect of pooling strength on the parameter values
One of the few well explained examples
Thanks a lot for this awesome presentation? Do you recommend particular packages and implementations on the topic?
Probably the clearest explanation of hierarchical models I’ve ever seen. Great video!
Amazing work. Thanks
Critical race theory is also quite racist. Just replace black with white in their writings, and you will see.
This is incredible. Thank you.
Amazing lecture!
The link to the blog referenced at the end is no longer accessible through it. Can I ask where I can find this blog?
Tunrayo taught me fractions - she really knows her stuff.
Great video, thanks !
Under Partial Pooling, why does sigma_a represent the degree of pooling?
Perhaps the best explanation. Thanks a hell lot
Wow, this has helped explained what hot deck is. Thank you!
❣️ 𝐩яⓞ𝓂𝓞Ş𝐦
Thanks for the informative video. In the end model in which uncertainty for different counties is very similar, isn´t the model understating this uncertainty for the cases with just 1 or 2 datapoints? Could you elaborate? Thanks!
Omar, it is not clear to me why sigma controls the amount of pooling. Could you point me into some sources to learn more about this? I enjoyed your presentation. Thanks.
Hi Noé, maybe I can have a go at explaining. When doing the hierarchical modelling, we suppose that the parameters for each group themselves come from a distribution. If we assume that this distribution has zero variance, we are saying that all of the group-level parameters must be the same - they must be equal to the mean. This is because there is literally zero variance. This is the same as pooling all the data (the first example). On the other hand, if we assume the variance is very large, then each group parameter has the freedom to choose any value it wants, without penalisation from the group model-parameter distribution. This is the same as having no pooling - each group has its own parameter. We can choose sigma between these two extremes to specify how closely linked the group parameter should be. Thank you and I hope that helped!
Hi @@williamchurcher9645. Correct me if I'm wrong: given the prior distribution of alpha_i is assumed as Normal(mu_alpha, sigma_alpha), if sigma_alpha = 0, all the alpha_i may not be (and can not be) equal because the mu_alpha is not a fixed number but follows a distribution Normal(0, 5). Put that in a formula to be clearer: alpha_i ~ Normal(mu_alpha, sigma_alpha) <=> alpha_i ~ Normal(mu_alpha, 0) <=> alpha_i ~ Normal(Normal(0, 5), 0) <=> alpha_i ~ Normal(0, 5) => alpha_i is not a constant but a distribution Following that understanding, the answer for why the sigma_alpha represents the degree of pooling is still vague.
this is really well explained.
Thanks for clear explanation. Very helpful.
Thanks Omar. Clear and helpful.
Bravissima.lezione eccellente
This is a great presentation. Learned a lot from it. Thanks for making it public.
Thank you for this well-paced video with its explanations. I feel much more confident in my understanding of Bayesian hierarchical modelling.
this company is corrupt and evil folks, expect another COMPAS scandal with their home office partnership, caveat emptor
This was great. Thank you Shailee
Had a hard time getting pystan to work on Windows. Anyy recommendation?
pystan
Use WSL :)
Don't use Windows. ;)
I spent 2 hours trying to install on windows, and 10 minutes installing in WSL (never having previously installed python in WSL)
Very nice talk, Thanks
Good. There were reports of errors in facial recognition systems in use by Law enforcement agencies in the USA.
Great presentation and super interesting content!
This is brilliant use of predictive AI for customer segmentation, and perfectly presented. Well done sir!
great idea!
Wow, thats really brilliant. And a fantastically lucid presentation!!
That's a great project! Thank you for sharing.
very interesting!
What does the error audit stream look like, and can it not also perhaps suggest much more productive use than identifying and blocking (definitely not the film school definition of blocking, I take it.) Also, feel free to presume I'd like a TL:DR text description rather than to cite who's explaining, if that's not anathemical to fine 600.000,00 euro bloom filter cobblin'.
