Preprint of our @ICSEconf #icse17 paper: goo.gl/k88d0b The Evolution of Continuous Experimentation #data #datadriven #casestudy

We started ExP blog in June 2020 and published twelve articles in year one (see below). What A/B testing topics are you interested in learning more about (and want to see in year two)? #abtesting linkedin.com/pulse/exp-blog…

"Ensuring we don’t harm reliability, performance, and user experience is the most important function of A/B testing during this time." Do you agree or have any other learnings that you observed in the area of A/B testing recently? lnkd.in/geBePqw

This impressive new tool from @IHME_UW will help hospitals, policymakers, and the general public better understand and prepare for the #COVID19 response in the U.S. b-gat.es/2QShVtV

@nytimes Idea to improve the trustworthiness of news articles using simple ML: USE NLP and alert the composer whenever the context about one country includes a capital city of another country.

Data Quality: Searching for a trustworthy newspaper to update me on the nuclear disarmament talks happening in Sweden today. Still searching. @nytimes the capital of #Sweden is Stockholm. #Helsinki is in Finland.

KDD 2019 paper: Diagnosing Sample Ratio Mismatch in Online Controlled Experiments at exp-platform.com/Documents/2019… . If you experiment, you MUST check for SRMs, or your system is not trustworthy. Period. Trivial implementation I shared: bit.ly/SRMCheck

@xLeitix Haha, I'm not using twitter too often :). Enjoy the paper. The Safe Velocity paper is also up on exp-platform.com now!

@afabijan A bit late to the party :)

@afabijan, who you can barely see in the pic, had developed three checklists for conducting a/b tests that actually mean something.

@afabijan @afabijan I would love to link to a preprint, but I could not find one (hint hint :) ).

Experimentation Epidemic in Software Industry – Are You Infected? #ABTesting #HiPPO linkedin.com/pulse/experime…

How good are companies at growing their experimentation programs and running #abtests at scale? Check our latest survey paper presented earlier today at SEAA'18 to answer this question! goo.gl/1x2T6u #experimentation #OEC #HiPPO #ABtesting

@p_diebold Good luck!

A great example of why you should run controlled experiments and not trust observational studies. #abtesting nytimes.com/2018/08/06/ups…

The only type of #HiPPO that we can trust. For everything else let's use #data.

@ronnyk @lukasvermeer

I specified on booking.com search that we will be traveling with a few months old baby, and yet one of the first results is a bed in a hostel room with 8 bunk beds.Designing a good #OEC is hard. Can the other guests handle my baby cry? #ABtesting

Let the #profes17 skiing day start!

Watching The Bing Bang Theory years ago finally paid off! Singing #softkitty shortens the time needed for my 3months old Annabelle to fall asleep. Results are statsig. Ongoing experiment with walking her around the room\not (control) pending @lukasvermeer

@matseinarsen 6. Evaluation yes, but most importantly, setting the direction in the first place.
