Machine Learning... what I have learned so far
Supervised Learning
Finding the right model to fit data
Like reverse Algebra
:
we only know x and y
Try to find the min delta
Multiple Params
Find the best model
Classification
True of False
y = 1/(1+ e^(-theta * X))
so y will always be (0,1)
Identify more than one:
one vs all
Regression
FTW!!!!!
Overfitting
One vs all is not very good...
Picking param is hard :(
Neural Network FTW!!!
No time, next time!
Rise of cheap machine!
