I got introduced to network pictures by Valtteri Kaartemo a few years back, and thought it was a cool idea. Since then, I’ve realized — after talking to many startups — that it’s more than a cool idea. It’s actually useful. That’s because startups routinely overlook their networks and just focus on competitors. They make positioning to competitors, not to…
This is a joint piece by Dr. Joni Salminen and Professor Jim Jansen. The authors are working on a system for automatic persona generation at the Qatar Computing Research Institute. The system is available online at https://persona.qcri.org. Introduction Personas are fictive characterizations of the core audience or customers of a company, introduced into software development and marketing in the 1990s (see…
Missing values are a critical issue in statistics and machine learning (which is “advanced statistics”). Data imputation deals with ways to fill those missing values. Andriy Burkov made this statement a few days ago [1]: “The best way to fill a missing value of an attribute is to build a classifier (if the attribute is binary) or a regressor (if…
Introduction At Qatar Computing Research Institute (QCRI), we are developing a system for automatic persona generation (APG).

People working in different domains are interested in different information, after all. For example, journalists want to know what…

The main challenges are: (a) how much the deviation should be to be classified as an anomaly, and (b) what time frame or subset of data should we examine. The simplest way to answer those questions is to use your marketer’s intuition. As an e-commerce manager, you have an idea of how…
I was chatting with Lauri [1] about platform research. I claimed that the research has not that many implications for real-world companies apart from the basic constructs of network effects, two-sidedness, tipping, marquee users, strategies such as envelopment, and of course many challenges, including chicken-and-egg problems, monetization dilemma, and remora’s curse (see my dissertation on startup dilemmas for more insights…
My friend Vignesh alerted me earlier this week that my site has been hacked and is forwarding to some malware site. At first, I called GoDaddy to ask for help. That was useless. It turns out their tech support consists of sales reps trying to sell you shit — no help for cleaning the site. They could it for me…
