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

Introducing my SQL Data Analyst Agent.

I'm excited to announce an addition to my AI Data Science Team in Python.

This is what it does: Image
The AI Data Science team is a free GitHub repo that helps you perform common data science tasks 10X faster.

This is the first multi-agent in my arsenal: The SQL Data Analyst.

It combines:
- SQL Code Writing
- Database Execution (run SQL queries, get data)
- Data Visualization (produce plots or tables)Image
