Which one is correct ?
A vector is simply an array of numbers
Row = feature / entity / attribute
output / prediction = independent variable
column = attribute / feature
What options are true for One hot encoding ...
It can prevent unnecessary ordering category
for each property a field has to be removed from the table.

algorithms are the specific representations learned from data
Algorithm is the result of using trained model
an algorithm becomes a model when it learns the value of coefficient/weight
Select correct answers ?
in Simple Linear regression it has single input variable
cost function is used to calculate the accuracy
"col-linear variables" means one input variable can be accurately predicted by the other
Linear regression is very sensitive to the distance among data points, so it's always a good idea to normalize or standardize the data
