Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube Channel:

In this hour, we will build off of the algorithms and material that we learned in our prior Machine Learning Lunch and Learns.

So far, we have covered Machine Learning examples and datasets that all are numeric. But much of the data in the world, and especially in healthcare, is textual data – clinical notes, coded descriptions and classification of information, etc. In this session, we will dive into the world of text. We will learn how to deal with category data through working with the Titanic dataset. We will use this information to predict who will survive the Titanic disaster based on each passenger’s attributes – numbers and text like age, fare, class of travel, gender, city they embarked from, etc. Secondly we will dive into free text and see how to learn from documents. In this case study, we will explore the IMDB Movie Review database and learn how we can train a model to read the textual movie review and predict whether the author liked or disliked the movie automatically. This is the field of Sentiment Analysis and is used by many organizations to review their public perception based on news and social media content.

2 good datasets, 2 good speakers, 1 good hour. Please welcome! 👏🏼


Don't forget to watch two previous webinars:

This has a similar issue to the 201 video in that it was interactive without the class having mics, so any responses or questions from them are basically lost. I far prefer interactive classes to online/video/canned ones, but only when I'm actually in them. Watching them, especially when you lose the participation portion due to mic problems, isn't great.

That said, this was still an interesting video, and I'm glad I watched it.
