In this article, we’ll talk about Pivot Tables in Python. We’ll implement the same using the pivot_table function in the Pandas module. What is a Pivot Table? Pivot Tables are a key feature of Microsoft Excel and one of the…
Splitting a dataset into training and testing set is an essential and basic task when comes to getting a machine learning model ready for training. To determine if our model is overfitting or not we need to test it on…
Clustering is a technique of grouping similar data points together and the group of similar data points formed is known as a Cluster. There are often times when we don’t have any labels for our data; due to this, it…
In this article, we will learn how to create Matplotlib subplots. In practice we often need more than one plot to visualize the variables, this is when subplots come into the picture. Matplotlib subplot method is a convenience function provided…
Even if you are not in the field of statistics, you must have come across the term “Normal Distribution”. A probability distribution is a statistical function that describes the likelihood of obtaining the possible values that a random variable can…
In this article we’ll see how we can plot K-means Clusters. K-means Clustering is an iterative clustering method that segments data into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centroid). Steps for…
Naïve Bayes Classifier is a probabilistic classifier and is based on Bayes Theorem. In Machine learning, a classification problem represents the selection of the Best Hypothesis given the data. Given a new data point, we try to classify which class…
We’ve already worked on PCA in a previous article. In this article, let’s work on Principal Component Analysis for image data. PCA is a famous unsupervised dimensionality reduction technique that comes to our rescue whenever the curse of dimensionality haunts…
A density plot is used to visualize the distribution of a continuous numerical variable in a dataset. It is also known as Kernel Density Plots. It’s a good practice to know your data well before starting to apply any machine…
