# Preface {-}
We see this book evolving across multiple aspects of advanced analytics (AA). Each section helps to answer important questions we get receive from other finance teams. The current layout is planned below.

* **Learning Path**: Dedicated to providing free resources to learn about Artificial Intelligence and Machine Learning at a high level, as well as content to dive deeper into the technical side. We hope this section gives your finance team to resources to ramp up on these new skills and develop data intuition to drive advanced analytics work on your team.

### Getting the Most out of Learning
[Deliberate practice](https://jamesclear.com/deliberate-practice-theory) is the best way of getting the learning to stick, and to rapidly evolve your skills.
**Whenever you learn something new in the data and AI world, it's best to usually apply it immediately to a real world project within your job or company.** By using a real world problem to practice what you just learned, you're able to reinforce the new knowledge into your long term memory while at the same time driving impact in your job by solving real problems. What a bonus! Be careful about only working on "toy datasets", which is public data that has been beat to death by hundreds of blogs and courses. The real world of data is messy and unpredictable, so working on things related to your current job or company gets you comfortable with that uncertainty even faster.

Don't feel bad looking up things on Bing/Google. Every technical person who works with computers today most likely looks up things online every day. Software syntax takes time to learn, and some of the best engineers still don't remember all the ins and outs of a language. When it doubt look it up online! Sites like Stack Overflow will quickly become your best friend as you try to work through issues in your code.

Learning how to manipulate data outside of existing tools like Excel or Power BI quickly give you data super powers you never thought possible before. Breaking out of the four walls of excel and into the data universe by leveraging languages like Python and R unlock so much more potential for impact in whatever job you do. Even if you don't plan to build your own Machine Learning models, knowing the basics of data manipulation is an important skill to have, and builds a data foundation that Machine Learning is built upon if you ever want to come back and start building models.

## Unsupervised Learning
Unsupervised learning is an evolving field of machine learning, and many say is the future of AI in general. Instead of relying on existing data with known outcomes to learn from like supervised learning (regression and classification), unsupervised learning tries to learn its own unique things about a data set without needing to know the answer ahead of time. This can be a game changer in finance when trying to segment customers into specific groups based on their purchasing behavior or finding anomolies to flag for potential fraud or corruption.

## Model Interpretability
A lot of times you may be asked to help understand how a particular machine learning model came up with its prediction. Knowing how to leverage various interpretability frameworks helps decode the black box of these models for better adoption by non-technical business partners and enables better understanding what features are most impactful in your model.
