Analytics used to ban texting while driving, or drunk driving, are flawed

It is certainly true that texting while driving (by young driver) is dangerous, and increases the risk of accidents. However how do we assess car crash risks?

  • Are young drivers better at multitasking, and causes mild crish when texting because they drive more slowly?
  • What about training them on minimizing risks while texting and driving, since making it illegal does not work?
  • Likewise, you can train alcoholics to drive better (since they will never stop driving…

How to avoid new bank fees: solution

Most banks are going to add small fees e.g. for debit card ($3/month in my case). Last time I went to my bank, I had this strange conversation:

  • I asked documents about the various types of accounts that they offer, as they suggested that I switch to a more upscale type of account, where there would be no fees
  • Instead of receiving the documents, I was forced to spend 15 minutes listening to a bank manager about the benefits of the upscale account. My hourly rate being…

Interesting note and questions on mathematical patents

I was reading about the "Automated Reduced Error Predictive Analytics" patent secured by Rice Analytics (see below) and my first question is:

How can you successfully sue competitors about using a mathematical technology? After all, most vendors offer error and variance reduction as well as dimension reduction and automated model selection (based on optimizing goodness-of-fit) in their software. All statistical and data mining consultants, including myself, also use similar…

Barriers to hiring analytic people

You hear all the time that it is very hard to find and hire a great data scientist. Yet these scientists can't find a job, and are typically unemployed for many months after graduating or after being laid off - even those with 15 years of experience and stellar degree and accomplishments. 

So what's the problem? I'm suggesting a few possibilities:

  • Candidates lack business acumen
  • Candidates have poor communication skills, are asking too much…

Creativity vs. Analytics: Are These Two Skills Incompatible?

In a nutshell, are great analytic people lacking creative skills? And are great creators lacking analytic skills? How to fix this gap?

Here are a few interesting questions:

  • Should analytic people focus on measuring, and nothing else? 
  • Do analytic people lack business skills because they were odd kids in high school, because the way the school system is working in US?
  • Is it impossible to hire great analytic people combining both soft and hard skills, because…

A potential new type of threat, incredibly difficult to detect, and absolutely vicious

You type in a domain name, say in your browser (say Chrome), and a website with broken links, broken images and badly formatted text, shows up. When you click on any link, it "redirects" you to what seems to be a true Wells Fargo page. You try with a different browser (say IE), and you experience the same problem. You visit, and you get an 310 error message saying "recursive redirect found on the web page". You do a…
