Exploratory analysis of big times series data
In addition to its Data Science services, VISEO developed a software, DeltaMetric, an exploratory analysis of big-time series data solution that answers Data Scientists’ needs. It is the most innovative solution for exploratory analysis of big times series data for data scientists.

DeltaMetric allows data scientists to optimize their time and improves the reliability of the delivered results.  

The solution assists Data Scientists in the understanding of sets of data. Thanks to that solution, it is now possible to build hypotheses while using the latest Visual Mining's innovations. 

DeltaMetric allows you to:  

  • Summarize multidimensional data graphically.  
  • Automatically detect uniform or unusual components.  
  • Quickly highlight discriminatory indicators. 
  • Use the time variable of the information in your representation and analysis. 
  • Boost your data with the creation of new indicators. 
  • Share complete and structure restitutions. 
  • Big Data ready: DeltaMetric can connect to any source of data.
