''Take aways / Key points:''
* A data scientist uses data to find solutions to problems and tells stories to communicate their findings.
* Data science is the study of large quantities of data, which can reveal insights that help organizations make strategic choices.
* Qualities of an analyst as per Murtaza Haider ( Ryerson University / Ted Rogers School of business):
** curious
** judgemental
** argumentative
* Terms to know:
** Overfitting.
** In-sample forecast
Commentary:
This course was weak.
The course basically makes three points:
# "You should get into data science, it's cool and there is a need."
# "Here are some examples of problems solved with machine learning."
# "Here is how to make a report. Cover page, summary , conclusion etc."
All three are low value in my opinion.
I want to get to the meat and start "doing it" not talking about how great it is.

Take aways / Key points:

  • A data scientist uses data to find solutions to problems and tells stories to communicate their findings.
  • Data science is the study of large quantities of data, which can reveal insights that help organizations make strategic choices.
  • Qualities of an analyst as per Murtaza Haider ( Ryerson University / Ted Rogers School of business):
    • curious
    • judgemental
    • argumentative
  • Terms to know:
    • Overfitting.
    • In-sample forecast

Commentary:

This course was weak.

The course basically makes three points:

  1. "You should get into data science, it's cool and there is a need."
  2. "Here are some examples of problems solved with machine learning."
  3. "Here is how to make a report. Cover page, summary , conclusion etc."

All three are low value in my opinion.

I want to get to the meat and start "doing it" not talking about how great it is.

Data leaks

When data associated iwth the data set gives away the target data.

Primarily of concern in competition.

Unexpected data.

refrence: https://www.coursera.org/learn/competitive-data-science/lecture/5w9Gy/basic-data-leaks

Future peaking - using time series data that's not in the target time period, for example in the future.

Meta data leaks - for example file meta data, zip file meta data, image file meta data.

information hidden in ID and hashes,

and information hidden in row order and possibly duplicate rows

Questions and Investigation

What are "ground truths"?

corteges - what is this word
