Exactly this time last year I had just begun my Data science journey so machine learning and programming were still quite new to me at the time. Over the past year, I had spent a lot of time and resources learning and practicing the various machine and deep learning techniques…

The term linear model implies the model is specified as a linear combination of features. Based on training data, the learning process computes one weight for each feature to form a model that can estimate or predict the target value. …

While a data scientist might have a variety of tools which they use for different purpose, most will that the Structured Query Language (SQL) is the one most important work tool a data scientist should have. …


Python Data types that are use for collections

Just before we move on, if you need to go through the basics of data types and variables, kindly check the previous post here: https://medium.com/dsn-ai-futa/variables-and-data-types-c427233e684b

DICTIONARIES

A dictionary is an associative container that contains the items in key/value pairs. The values of key-item data structure (unlike lists and strings that can…

A variable is a container used to store and hold data. It can be seen as a Python object used in storing and holding data for re-usability later on during the program. These data can come in different types which will be discussed in subsequent sections below.

Variable assignment is…


Proper visualization enhances better hindsight

Understanding your data and the relationship present within it is just as important as any algorithm used to train your machine learning model. In fact, even the most sophisticated machine learning models will perform poorly on data that wasn’t visualized and understood properly. …


Problem Definition

‘You have been called in by CEO of company ‘X’ to use your machine learning skills to study the pattern of promotion. With this insight, he can understand the important features among available features that can be used to predict promotion eligibility’

Before proper data modelling can be done for…


Atoms make up everything. Objects give them functions

What is Object Oriented Programming (OOP)?

Most developers — python developers especially — will agree that early in their careers/their learning stage, the concept of Object Oriented Programming seemed strange, both it’s purpose and usefulness. A common misconception among beginners is that OOP is a special tool/design similar to function creations, used to solve a particular…
