In a previous post we looked at root-finding methods for single variable equations. In this post we’ll look at the expansion of Quasi-Newton methods to the multivariable case and look at one of the more widely-used algorithms today: Broyden’s Method.
How do you find the roots of a continuous polynomial function? Well, if we want to find the roots of something like:
I recently did some A/B testing work through the Facebook advertising platform, and gave a quick presentation on the pros and cons of the platform. Here’s a summary.
- Inexpensive, low ceilings
- Demonstrated to work at scale, sophisticated distribution
- Click bots
To clarify my perspective on the platform, some background on the work we did:
We ran some A/B tests through the platform targeting a specific population, evaluating different levels of resulting engagement for statistical significance. I assure you, nothing fancy. Continue reading “Understanding Facebook Ads: Pros and Cons”
