Data generation and analysis are not sufficient.
Consuming it as a team and acting in cohesion is.

Слайд 18This plot shows the frequency of all meter readings from Apr-2010

to Mar-2011. An unusually large number of readings are aligned with the tariff slab boundaries.

This clearly shows collusion of some form with the customers.

This happens with specific customers, not randomly. Here are such customers’ meter readings.

If we define the “extent of fraud” as the percentage excess of the 100 unit

meter reading, the value varies considerably across sections, and time

New section manager arrives

… and is transferred out

… with some explainable anomalies.

Why would these happen?

Based on the results of the 20 lakh students taking the

Class XII exams at Tamil Nadu over the last 3 years, it appears that the month you were born in can make a difference of as much as 120 marks out of 1,200.

June borns score the lowest

The marks shoot up for Aug borns

… and peaks for Sep-borns

120 marks out of 1200 explainable by month of birth

An identical pattern was observed in 2009 and 2010…

… and across districts, gender, subjects, and class X & XII.

“It’s simply that in Canada the eligibility cutoff for age-class hockey is January 1. A boy who turns ten on January 2, then, could be playing alongside someone who doesn’t turn ten until the end of the year—and at that age, in preadolescence, a twelve-month gap in age represents an enormous difference in physical maturity.”
-- Malcolm Gladwell, Outliers


Слайд 24Let’s look at 15 years of US Birth Data
This is a

dataset (1975 – 1990) that has been around for several years, and has been studied extensively. Yet, a visualization can reveal patterns that are neither obvious nor well known.

For example,
Are birthdays uniformly distributed?
Do doctors or parents exercise the C-section option to move dates?
Is there any day of the month that has unusually high or low births?
Are there any months with relatively high or low births?

Very high births in September. But this is fairly well known. Most conceptions happen during the winter holiday season

Relatively few births during the Christmas and Thanksgiving holidays, as well as New Year and Independence Day.

Most people prefer not to have children on the 13th of any month, given that it’s an unlucky day

Some special days like April Fool’s day are avoided, but Valentine’s Day is quite popular



More births

Fewer births

… on average, for each day of the year (from 1975 to 1990)


Слайд 25The pattern in India is quite different
This is a birth date

dataset that’s obtained from school admission data for over 10 million children. When we compare this with births in the US, we see none of the same patterns.

For example,
Is there an aversion to the 13th or is there a local cultural nuance?
Are holidays avoided for births?
Which months have a higher propensity for births, and why?
Are there any patterns not found in the US data?

Very few children are born in the month of August, and thereafter. Most births are concentrated in the first half of the year

We see a large number of children born on the 5th, 10th, 15th, 20th and 25th of each month – that is, round numbered dates

Such round numbered patterns a typical indication of fraud. Here, birthdates are brought forward to aid early school admission



More births

Fewer births

… on average, for each day of the year (from 2007 to 2013)


Слайд 26This adversely impacts children’s marks
It’s a well established fact that older

children tend to do better at school in most activities. Since many children have had their birth dates brought forward, these younger children suffer.

The average marks of children “born” on the 1st, 5th, 10th, 15th etc. of the month tend to score lower marks.
Are holidays avoided for births?
Which months have a higher propensity for births, and why?
Are there any patterns not found in the US data?



Higher marks

Lower marks

… on average, for children born on a given day of the year (from 2007 to 2013)

Children “born” on round numbered days score lower marks on average,
due to a higher proportion of younger children

How does Mahabharata, one of the largest epics with

1.8 million words lend itself to text analytics?
Can this ‘unstructured data’ be processed to extract analytical insights?
What does sentiment analysis of this tome convey?
Is there a better way to explore relations between characters?
How can closeness of characters be analysed & visualized?
