FSHM Weekly -7/03/20
We were conducting machine learning classes for past 5 Weeks at maitri every Saturday 6:30 pm
The topics we were covered so far :
1.Machine learning introduction;
2.Regression
* Centrality- mean,mode,median, variance
3.Distributions
*Gaussian distribution
* Binomial distribution
4.Data prepocessing - consists of testing, validation,training.
Here is our today's session summary:
FUNCTIONS
Definition:
The mapping of elements from domain to co domain
Our Gokul differentiated continuous and non continuous function with a simple graph, then Arun describes about co-variance and explains how it differ from independent
We concluded the session by discussing on K nearest neighbours and it's drawbacks...
IMPORTANT FORMULAS :
1.F is continuous at x,if
ε>0,|f(x-γ)-f(x-γ)|<ε
2.variance= summation of 1 to n (x-µ)^2
3. In K nearest neighbours
Distance formula=
√(x1-x2)^2+(y1-y2)^2
