PYTHON

Please use python code and screenshots

I need general sample code to do these:

- I have a training data and I created a bigram and unigram dictionary for that training data.

I need help with calculating probability for each file. It is done using Each bigrams probability with Laplace smoothing is: (b + 1) / (u + v) where b is the bigram count, u is the unigram count of the first word in the bigram, and v is the total vocabulary size (add the lengths of the 3 unigram dictionaries).

Please give a sample code to calculate probability per instruction stated above.

- Compute and output your accuracy as the

percentage of correctly classified instances in the test set. The file LangId.sol holds the correct classifications.

Please give sample code for how to compute and output accuracy.

-output your accuracy, as well as the line numbers of the incorrectly classified items.

Please give sample code for above statement.

Thank you so much.
