While working with Jupyter notebooks, all the codes, etc. get saved at a default directory. One might want to keep their projects organized and hence comes the need to keep your codes in the correct folder.

I tried changing the default directory using the command prompt. But got an error ( Screenshot below).

The error I faced in cmd

But then I tried the same in Anaconda Prompt and it worked!

The simple steps are ( for Windows):

  1. Go to Start and search for Anaconda prompt
  2. Once it opens, type cd followed by the path.

Most of the world suffers because of the unfathomable greed of a select few.

Sometimes (more than sometimes, for me), you wonder what exactly are you doing in life. Going to your job, giving your best there, perhaps thinking about work/ working way beyond your office hours. But what all for? A paycheck? Yes. But what else? Are you really making anyone’s life better…

What is Machine Learning? How is it different from rule based approach?

Machine learning allows a system to learn from data. Contrary to rule based approach, where the logic is hard-coded (and would have to be updated, to reflect iterations basis new observations etc.), Machine learning looks at the data to pick up patterns.

Machine Learning algorithms could pick up on elements that a human could have overlooked, or not deemed important. Also, it is not most feasible to code a lengthy list of rules.

Machine learning looks at the data to figure out the patterns/rules, eliminating need of a human to formulate those.

PS: Any comments, corrections etc. are welcome.

Couldn’t decide on a pic. Really got into printing.

Data science is the sexiest job of the 21st century. This is how most posts about why should get into data science begin. This thought has for sure ensured that many engineers, people in technical roles, and many other folks, pivot to it. …
