Python Decorator Pattern
Diversify your Python functions by decorating them
Sometimes we need to modify or change the behaviour of a function in a loosely coupled manner. Learn how to do this in this 10-minute video.
Python Factory Pattern
Find out why this 'anti-pattern' is useful
Experiment with this pattern in a Pythonic way. Use the example code.
Text Classification Using Keras LSTM, CNN and embeddings
A no-fuss pipeline for binary or multiclass text classification
Exploiting the temporal and spatial aspects of text for classification is easy.
Regressor as Classifier
... it works better than you think.
A classifier predicts a categorical target variable while a regressor predicts a continuous response variable. Can we fit a regressor as a classifier? Let’s find out.
Are Outliers Always a Problem?
no...sometimes we need to treat them with respect
Outliers are mostly seen as not needed. We will see an example where this is not true.
Calibrate Your Classifier
you might wonder how you were doing without it all along
Would you buy oranges weighed on an uncalibrated weighing scale? Then why would you trust an uncalibrated classifier?
Longest Common Subsequence
...with an unconventional approach
This is a three way LCS solution using a ‘sparse’ data structure and an intuitive conceptual model to aid your understanding.
Roc Curve Step by Step
...with precision-recall curve thrown in
The ROC curve is an important metric to compare classifiers. Learn how to draw one step-by-step.
Linear Regression From Scratch
Don't just tow the line, move it!
Imagine you are buying a car and you want to know about its mileage. You don’t want to go for the user reviews or the company’s claim of mileage. The option you are left with is to predict the mileage all by yourself. So, if you are an interested data scientist, why not give it a try?
Mergesort Cutaway
Sorting an array can be done in different ways. It ranges from the simpler bubble sort to more complicated ones such as the merge sort.
