Don’t Allow Yourself to Be Hoodwinked by Unstructured Data Analytics Technology

By JIANG Buxing, Data Scientist 

As big data concept gains momentum, unstructured data analytics technology is becoming hot.  It is said that 80% of all data in an enterprise is unstructured, which is roughly true when it is measured by the space, considering the large size of the audio and video data. With huge amounts of data at hand, some technique is required to analyze them.

But make sure you are not misled by the universal unstructured data analytics…

On Saturday February 11, 2017, my daughter and her friend were driving from a basketball game in Chico back to our home in Palo Alto. Unfortunately, due to several days of heavier than normal rains, the Oroville Dam spillway broke and flooded many of the roads between Chico and Palo Alto. My daughter’s smartphone mapping application wasn’t aware of the sudden danger, and proceeded to send her into the heart of the flooding (see Figure 1).…

Better Banking with help of Analytics and Machine learning

In 2015, I was working at Diebold where we build ATM machine hardware and software and complete ecosystem around the ATM. When we talk about ATM machine, it is a collection of very complex small hardware which collectively performs tasks. And typically, when we think ATM is only used for cash withdraw and that is not true. When we talk about ATM it is a Bank branch itself. You can deposit cash, withdraw cash, deposit cheques. And Whatever we can do in the branch we can do with…

Four Ways to Improve Back-end Performance for Multidimensional Analysis

 

By JIANG Buxing, Data Scientist 

Multidimensional analysis, commonly called OLAP, is an interactively data analysis process that performs operations, including rotation, slice and dice, drilldown etc., on a data cube. The structure of its back-end computation is simple, as shown by the following SQL:

SELECT D,..., SUM(M), ... FROM C WHERE D'=d' AND ... GROUP BY D,...

The statement…
