Wed, Dec 13, 2023, 6:00 PM ESTDataPhilly Presents: Fast.AI Course Launch!
1839 Chestnut St, Philadelphia, PA
Hi Data Enthusiasts,

"Andrej Karpathy told me at Tesla pretty much everybody that joins Tesla AI is made to do this course. At OpenAI (they told me) the residents there first do this course" - Jeremy Howard FAST.AI

We are excited to announce a new learning opportunity for our community! We kindly invite you to our very first live session where we will go over the Fast.AI course. Why are we doing this? It's because there are many new data scientists, existing data scientists who are interested in the course and we understand that learning is easier when done in an environment community! This is an exciting learning opportunity, a can't miss chance to learn from your fellow data enthusiasts!!

Action Items (For those interested):

We'll be discussing and going over the first lecture in the Fast.AI lecture series. Start Watching Lesson 1 NOW!

Please watch the first video lecture and we'll be helping people setup with Google Colab or Paperspace to run their Jupyter Notebooks if they haven't already and discussing any confusing bits.

Join the DataPhilly Channel then find the #fastai-study-group

Logistics:

Virtually (Please see the Zoom link)

In Person @ Commonwealth Proper Men's Shop on 19th and Chestnut ( 1839 Chestnut). It's located on the ground floor across from Mookies Smoke shop on 19th Street

Link visible for attendees
Abstract:
Often a formula allows a quick calculation of an answer but does not provide insight into the concept. This talk uses cartoons to develop subtleties of a commonly used metric for classifiers (ROC Curve) and subtleties associated with the model coefficients for Logistic regression.

The first part of the talk develops the logic of the ROC curve, a common measure of model quality that can be used for any classifier. In most classes a student is simply told that the ROC curve should go up vertically and then go horizontally. A student is also told that a 45° ROC curve is not good. Using some pictures we can develop a much deeper understanding and show that the ROC curve is intuitive and contains much more information than is commonly taught.

The second part of the talk discusses the C statistic -which is the area under the ROC curve. Most students are simply told that the area under the ROC curve has an upper limit of 1 and that an area close to 1 indicates a good model. This example illustrates some of the subtleties that are typically left uncovered in most classes and points towards the need for better performing performance measures,

The third part of the talk explores some of the subtleties of the beta values in Logistic regression, a tool that's still commonly taught and used. The beta values, the coefficients in the model, are not discussed in most classes, however they have some very interesting managerial implications. This section uses pictures to surface some of those managerial implications.
