Machine Learning Training Course (3+ days

 

Note: this outline is our proposal, but the training can be tailored to your specific requirements upon prior request ahead of the proposed course date.

Why Learn Machine Learning?

Machine Learning brings together computer science and statistics to harness that predictive power. It’s a must-have skill for all aspiring data analysts and data scientists, or anyone else who wants to wrestle all that raw data into refined trends and predictions.

This is a class that will teach you the end-to-end process of investigating data through a machine learning lens. It will teach you how to extract and identify useful features that best represent your data, a few of the most important machine learning algorithms, and how to evaluate the performance of your machine learning algorithms.

Course details

This outline can cover both fundamental and advanced topics.

This is a classical ML course, but depending on your branch/profile/needs there are a few possible course variations:

 

- Machine Learning with Python/R

- Machine Learning with Scala and Apache Spark
- Machine Learning and Deep Learning
- Machine Learning for Banking - with Python/R
- Machine Learning for Finance - with Python/R

 

The final training outline will be designed depending on your particular requirements.

The practical exercises constitute a big part of the course time, besides demonstrations and theoretical presentations. Discussions and questions can be asked throughout the course.
