EXAMPLE ESSAY QUESTION —
We all understand the benefits of laughter.
For example, someone once said,
“Laughter is the shortest distance between
two people.”
Many other people believe that laughter is
an important part of any relationship. Tell a
true story in which laughter was one
element or part.
We can work
with difficult
data —
The winning model
correctly predicted
seizures 82% of the
time. Until that point,
researchers had
struggled to develop an
algorithm that did better
than chance

engineering
matters most
Good software
engineering
practices and
robust statistical
methods are key
80% of data science is grunt work and only 20% involves deep thinking
A good pipeline makes data scientists more productive and their work higher quality and more
enjoyable
Our workflow environment will be the central repository for all data science work in a company

Notas do Editor

  1. People currently come to Kaggle
  2. We score their solutions in real time.
  3. Palantir is really starting to own the reporting layer. We want to own optimization and predictive modeling. Our competition platform gives us a head start in this direction.
  4. People don’t come to us with churn or cross sell, but they typically come to us with their hardest problems, and I’ll talk more about this soon. It’s for these reasons that we continue to invest in the competition platform. It’s a very efficient operation. It’s currently running with a headcount of 4. We believe 6 is the right long term number of people to invest in competitions. We decided to focus on Oil & Gas because after working with ~25 Fortune 500s and 12 industries, we believe it’s the biggest opportunity for machine learning and most ripe for disruption. Specifically because: Greatest value add: Huge gap between what they’re doing and what’s possible Shale is disruptive: the industry is looking for new ideas making it a good environment to be selling into.
