Your Must-Know Tweaks & Tricks

Have you got a hierarchical classification task that’s just begging for a machine learning model? Have you decided opting for an ensemble of local classifiers, and even decided on the best local-classifier structure for that very task? Is your keyboard all warmed up, fingers ready and raring to go? Well, just a minute now. You might wanna sit back down.

If you’ve read my previous posts on the subject of hierarchical classification, you have definitely got all the basics down. However, there are some important final details you should make yourself acquainted with. Whether it’s how to choose your training examples and feature sets, how to avoid error propagation, or ways to handle classification inconsistencies  this is one post you want to read before implementing your first real-life hierarchical model.

Before We Dive In

The topic of hierarchical local classifiers is a lengthy one, and understanding the intricacies described below requires you to be familiar with:

  1. Data Taxonomy & Hierarchical Classification
  2. Hierarchical Local Classifiers and their Different Structures

If that’s not the case, go ahead and read about them. It’s okay. We’ll wait.

Throughout this post, as in my previous ones, I’ll be giving examples based on this taxonomy of common house pets:

Down to Business

Are you building your very own hierarchical ensemble model? Have you defined your data taxonomy, picked out your favorite local-classifier structure, rolled up your sleeves, and you’re all set to go ahead and get that model cracking?

You’re almost there, champ. But before you turn that data sciencing engine on, there are just a few more points you should take the time to consider.

4 Pandas GroupBy Tricks You Should Know

Use Pandas GroupBy more flexibly and creatively

As one of the most popular libraries in Python, Pandas has been utilised very commonly especially in data EDA (Exploratory Data Analysis) jobs. Very typically, it can be used for filtering and transforming dataset just like what we usually do using SQL queries. They share a lot of similar concepts such as joining tables. However, some features from them have the same names but different concepts. “Group By” is one of them.

In this article, I’ll introduce some tricks for the Pandas group by function, which could improve our productivity in EDA jobs. Hopefully at least one is something you never familiar with so that it could help you.

I’m sure that you know how to import Pandas in Python, but still, let me put it here. All the rest of the code in this article assume Pandas has been imported as follows.

import pandas as pd

Why You Must Know Abstraction?

One of the fundamental concepts in Oop that you must know.

Through this article, I will be discussing the concept of **_Abstraction _**and how we can achieve it partially or completely in java programming. I have already covered other important pillars of OOPs that are InheritancePolymorphismEncapsulation, and Compositions. After reading this article you would be in a position to answer this question in your next interview.

What Is Abstraction?

It is one of the pillars of OOP like InheritanceEncapsulation, and Polymorphism.The basic English meaning of Abstraction is the quality of dealing with ideas rather than events. Did you get it? I know it’s hard to grasp.Let me put its definition in another way **basically it deals with hiding the internal details and showing the essential things to the end-user.**A real-life example of abstraction can be using an electric circuit board. We use the buttons to turn on and off the electrical devices through the circuit board. We know a lot of things happen inside the board. Here we are using the functionality provided and we aren’t interested in the actual working of the circuit board.Now let’s relate this example with classes and interface. The surface of the electric board is an Interface and the actual implementation of the electric circuit board is a class.
