Machine Learning: Cost and Loss Functions

[lachlandeer]

A cleaned up branch of @K-sohooli 's that discusses Loss functions and cost functions in the context of machine learning.

@K-sohooli a to do list:

• [ ] Where did the images come from? Are they public domain? (or have they been taken from elsewhere)
• [ ] can you check that i moved all the images across?

Please make all changes in this branch! git checkout topic/ml-loss-cost-function-define

Let me know via tagging me in a comment with answers to the above, and then we can do a next review before integrating,

Thanks!

@K-sohooli --

Can you let me know the answers to the two question above?

Cheers, L

Hi @lachlandeer , Regarding the source of images, "countourmap_2d" and "2_dim_costfunction" are taken from a course by Andrew NG on the Coursera platform. However, I am not sure if these images are protected by copyright law. If it is needed, I can create these images in Python to avoid any consequences. please let me know if I should create them myself. And about the other images, I created them in Microsoft Word and draw.io . regarding the second question, yes all the images relevant to this article are included.

Hi @K-sohooli

What license does Andrew Ng have on his course material? Can you please check whether we can use these images? Else we'll need to create new ones...

Cheers Lachlan

Hi @lachlandeer , the 2 images are updated. I created them in Python.
