Difference between probability and likelihood

Probability and Likelihood


Probability  is the quantity mostly familiar with which deals predicting new data given a known model

'Posterior Probabilities' : because they are determined after the results of the model are known.

In short, what is chances given feature data 


Likelihood  is deals with fitting models given some known data are the posterior values for the fixed data points with distributions that can be moved. assume that already assumed, indicate how likely the event under consideration is to occur given each and every a priori probability.

In short, which model or features should more likely given chances or probability

Priori Probabilities :  exist before we gain any information from the model itself.

Python program to check if variable is of integer or string

Let's say if you want to input something of any datatype and want to get datatype only of it. So... Whenever you input some data whether it is string, integer or float like this: i = input('enter something here: ') means without int, str or float put before the syntax, that time your given input is always consider as string  or if you make it like this to add int before syntax; i = int(input('enter something here: '))  it always consider as integer and gives value error when you input string and same thing happens with float, So here is a program to solve this problem of input and get datatype var = input('input to check if variable is of integer or string: ') if var.isdigit() == False:     print(type(var)) else:     var1 = int(var)     print(type(var1))

Digit Recognition

Here you can import digit dataset from scikit learn library which is in-built, So you don't need to download from other else Note: If you use visual code, I recommend you to turn your color theme to Monokai because it has a few extra and important keyword and attractive colors than other theme.   # %%  Import libraries import  numpy  as  np import  pandas  as  pd import  matplotlib.pyplot  as  plt import  random  # %%   Load dataset from  sklearn.datasets  import  load_digits dataset  =  load_digits() dataset.keys() output: d ict_keys(['data', 'target', 'target_names', 'images', 'DESCR']) You have to check all to direct print them Here DESCR is a description of dataset # %%   divide the dataset into input and target inputs  =  dataset.data target  =  dataset.target # %% ...
