You may consider it a histogram, but for categorical data, it’s a very simple plot and very useful, especially when doing exploratory data analysis in Python. Check out the countplot() function in the Seaborn library. First, we will import the Seaborn library and load some data from the ...
Replace values is a common task during Exploratory Data Analysis (EDA). If you explore data regularly, probably you’ve faced more than once the need to replace some values, create some sort of categorization or simply replace a value that you needed to be shown some other way. There are ...
To illustrate this concepts, let us do a simple exploratory data analysis on a dataset that is far to large to fit into RAM of a typical laptop. In this article we will use the New York City (NYC) Taxi dataset, which contains information on over1 billiontaxi trips conducted bet...
From finance to artificial intelligence, data science to web development, there isn’t an area in which Python isn’t consolidated and flourishing. So let’s discuss actual salaries, in-demand skills, marketplaces, and what to do in order to remain competitive. Find remote jobs in tech, ...
In machine learning, we save trained models in a file and restore them to compare each with other models. We can also test them using new data. The save process is called Serialization, while restoration is called Deserialization. We use a helper Python library called Pickle t...
