Excel with ML

Building neural nets in Excel likely makes me a certified maniac. Or would be, if such a certification was available from a credible academic body.  But spreadsheets are a great way to build your intuition and SEE how the algorithms work.  No black boxes.

I've used spreadsheets to teach machine learning to over 100,00 people and enjoy switching on "light bulbs" in others. If you've ever asked yourself any of these questions, you're in the right place.

  • "What do I need to learn first? Python? Jupyter?  Tensorflow? (INSERT LATEST TOOL HERE)?"
  • "What's the difference between AI, machine learning, and deep learning?"
  • "How does machine learning work under the hood?  What's the intuition?"
  • "How will I find the time to learn all this?"

As Andrew Ng says, "AI is a superpower," and you can learn it using a tool you already know.

Good ol' Mr. Excel is the easiest way to get ahead, demystify AI, and future-proof your career without quitting your day job.
