Experimentation and Testing: A Primer

Occam's Razor

This post is a primer on the delightful world of testing and experimentation (A/B, Multivariate, and a new term from me: Experience Testing). There is a lot on the web about A/B or Multivariate testing but my hope in this post is to give you some rationale around importance and then a point of view on each methodology along with some tips. It is important to realize that experimentation and testing might sound big and complex but it is not.

Experiment or Die. Five Reasons And Awesome Testing Ideas.

Occam's Razor

There is a tendency to think experimentation and testing is optional. Just don't fall for their bashing of all other vendors or their silly claims, false, of "superiority" in terms of running 19 billion combinations of tests or the bonus feature of helping you into your underwear each morning. For example I am quite fond of the fact that with Offermatica you can "trigger" tests based on behavior. I cannot recommend enough the wisdom of starting with a A/B test.

The Lean Analytics Cycle: Metrics > Hypothesis > Experiment > Act

Occam's Razor

Sometimes, we escape the clutches of this sub optimal existence and do pick good metrics or engage in simple A/B testing. The book introduces a wonderful process called the Lean Analytics Cycle, which aims to help you create a sustainable way to pick metrics that matter by tying them to fundamental business problems, creating hypotheses you can test and driving change in the business from the learnings you identify. Testing out a new feature. This should not be news to you.

Measuring Incrementality: Controlled Experiments to the Rescue!

Then they isolated regions of the country (by city, zip, state, dma pick your fave) into test and control regions. People in the test regions will participate in our hypothesis testing. So for variation #3, no catalogs or email were sent to the customers in the test group. The nice thing is that you can also test that! Work as hard as you can, and then some, to ensure that there are as few "disturbances" in your test and control group.

Machine Learning Product Management: Lessons Learned

Domino Data Lab

Pete indicates, in both his November 2018 and Strata London talks, that ML requires a more experimental approach than traditional software engineering. It is more experimental because it is “an approach that involves learning from data instead of programmatically following a set of human rules.” Because the nature and approach of ML projects is more experimental, industry people and their companies won’t know what will happen until they try it (i.e.,

Interview with: Sankar Narayanan, Chief Practice Officer at Fractal Analytics


Fractal’s recommendation is to take an incremental, test and learn approach to analytics to fully demonstrate the program value before making larger capital investments. Finally, the test and learn approach and accountability should be strengthened so that algorithm-driven insights are given a fair shot to be incorporated into decision making. It is also important to have a strong test and learn culture to encourage rapid experimentation.

MNIST Expanded: 50,000 New Samples Added

Domino Data Lab

Recently, Chhavi Yadav (NYU) and Leon Bottou (Facebook AI Research and NYU) indicated in their paper, “ Cold Case: The Lost MNIST Digits ”, how they reconstructed the MNIST (Modified National Institute of Standards and Technology) dataset and added 50,000 samples to the test set for a total of 60,000 samples. Many data scientists and researchers have used the MNIST test set of 10,000 samples for training and testing models for over 20 years. Did they overfit the test set?

A/B testing is used widely in information technology companies to guide product development and improvements. For questions as disparate as website design and UI, prediction algorithms, or user flows within apps, live traffic tests help developers understand what works well for users and the business, and what doesn’t. Nevertheless, A/B testing has challenges and blind spots, such as: the difficulty of identifying suitable metrics that give "works well" a measurable meaning.

Humans and AI: AI and Individuality

Announcing Domino 3.3: Datasets and Experiment Manager

Domino Data Lab

Models are so different from software — e.g., they require much more data during development, they involve a more experimental research process, and they behave non-deterministically — that organizations need new products and processes to enable data science teams to develop, deploy and manage them at scale. And “Experiment Manager” gives data scientists a way to track, find, and organize all the ideas they have tested over the course of their research.

How Analytics by Design Tackles The Yin and Yang of Metrics and Data

Misadventures in experiments for growth

The Unofficial Google Data Science Blog

by MICHAEL FORTE Large-scale live experimentation is a big part of online product development. This means a small and growing product has to use experimentation differently and very carefully. This blog post is about experimentation in this regime. Now how is it possible for these fledgling products exist, do something, have enough users that one could contemplate experimentation, and yet still not have market fit?

The Role of Theory in Data Analysis

Simply Statistics

Many data analysts are not involved in the data collection process or the experimental design and so it is important to inquire about he process by which the data came to them. For example, one person told me a story of an analysis she did on a laboratory experiment that was ostensibly simple (basically, a t-test). In data analysis, we make use of a lot of theory, whether we like to admit it or not.
