NLP – Word segmentation
Word segmentation
This is the act of taking a string of text and deriving word forms from it. Example: A person scans a handwritten document into a computer. The algorithm would be able to analyze the page and recognize that …
NLP – N-grams
N-grams
A combination of multiple words together is called N-Grams. N-grams (N > 1) are generally more informative as compared to words and can be used as features for language modeling…
NLP – Tokenization
Tokenization
It’s the process of breaking down the text into sentences and phrases. The work entails breaking down a text into smaller chunks (known as tokens) while discarding some characters, such as punctuation.

Python – Functions
Functions
A function is a rule for taking zero or more inputs and returning a corresponding output. In Python, we typically define functions using def:
def double(x):
"""this is where you put an optional docstring
that explains what the function Linear Regression – Cons[2]
Prone to outliers
Linear regression is very sensitive to outliers (anomalies). So, outliers should be analysed and removed before applying Linear Regression to the dataset.…
