When you really want to find a pattern in data, you will. Even if there is no pattern. What happened to me yesterday was embarrassing… it also is a lesson worth sharing. I learned how to interpret unusual data patterns,
My Machine Learning classifier’s prediction accuracy improves with the growing volume of train data. But at the same time, its precision falls. Why so? And how to fix it? Read on. reducing the problem to classification At Sopra Steria, we
I am looking at distribution of a certain data set (left). It has two peaks (this is called ‘bimodal’) therefore I suspect that those are two overimposed populations. How do I split the data, to rediscover the original two populations
Here is quite intriguing research with the data of our Sopra Steria IT operations (ITSM, AIOps, and Infrastructure Management). I’ve been faced with an interesting situation in an IT Applications Management project for a large corporate client. In such a

I recently work a lot with IT Infrastructure Management data. At Sopra Steria, we manage sizeable ecosystems of our corporate clients that include thousands of apps and infrastructure elements. We handle events, incidents, alarms, and support tickets. We process thousands
Following on my previous post, we have spent some time on building an internal Data Lake at Sopra Steria. The infrastructure is functional now and admitting its first users. Much has been said on building successful Data Science teams. Multidisciplinary
