3. Tidy Finance with #R

What tools exist in R for #Finance?
And how do I use them?

Answers to these questions are covered in this book!

P.S.- This book uses my R package, #tidyquant

5. #Forecasting Principles and Practice

This is the best “theory” book on #timeseries analysis and forecasting.

Topics Covered:
- ARIMA,
- Exponential Smoothing,
- TimeSeries Decomposition
- A lot more!

Data Scientist vs. AI Engineer (Generative AI Edition)

I've been studying AI for 18 months. This is what I discovered about the rise of this new role:
1) Context: The Rise of AI Engineering

- Data scientists have been called the “sexiest job of the 21st century.”
- But generative AI breakthroughs have led to a new role: AI engineers.
- Think of data scientists as data driven decisioneers vs. AI engineers as AI system builders.
2) Use Cases

Data Scientists:

- Focus on descriptive & predictive analytics (e.g., EDA, clustering, regression, classification).
- Turn messy data into actionable insights.

Can AI do Time Series Forecasting?

This is what I found out. Image
Over the past 2 years, I've been studying AI. Why?

Because there are 1,000s of ways we can combine AI with Data Science.

Time series is one of them. Image
Most people have bad results with AI. And Time Series is no different.

Time Series is niche.
It's nuanced.
Practitioners have a set of steps that they follow.
These steps can differ from person to person. Image

Can AI do Machine Learning?

8 weeks ago I didn't think so. But today I built my first ML Agent that made 30+ ML models in under 30 seconds.

The story is wild: Image
Agents are going to revolutionize Data Science and Predictive Analytics. Agents can...

plan

generate code

fix code

store outputs from code

use those outputs to do some task (e.g. prediction) Image
I decided to experiment with AI to see if I could make an agent capable of performing ML tasks at a high level.

What happened shocked me:

Here's a wild time series package in Python:

Let me introduce you to Stumpy: Image
Stumpy is a very unique library.

It computes a "matrix profile"

That's the secret sauce that allows you to do all these tasks:
Why a Matrix Profile? (because you can do this):

1. pattern/motif (approximately repeated subsequences within a longer time series) discovery

2. anomaly/novelty (discord) discovery

3. shapelet discovery

4. semantic segmentation
