In the following video, we discuss prediction using linear regression-based models. I am confident that if someone watches the video till the end, the concept of prediction using linear regression will become crystal clear. Many fundamental questions might still remain …

Today’s video discusses a way to find the optimal number of clusters, especially when we do not have any benchmark data. The question here is — Given a dataset and no supervision, how can we figure out what number of …

Today, I will describe an initial way of exploring and analyzing data using Pandas in Python programming. Exploratory Data Analysis There is a process called Exploratory Data Analysis, which refers to the initial investigation of data. The phrase “the initial …

As I was saying in the previous part, we will not get an interactive graphical interface if we use Google colab. That is why I am using regular Python on my computer. When I use Python, my program needs to …

In this part I discussed how we can visualize data points and clusters formed by those data points. The library we used is called Matplotlib. I imported the pyplot facilities of Matplotlib for the visualization of data points using Python. …

Hi, this is Dr. Shahriar Hossain again. Today, we will discuss an unsupervised machine learning algorithm and use the scikit-learn machine learning library. The concept I will discuss is called clustering. The specific algorithm that we will look at is …

Hi, This is Dr. Shahriar Hossain. I will go over an unsupervised learning algorithm using Python programming language soon. While explaining unsupervised machine learning to the audience, I figured that some terms are confusing for people who have just recently …

We are starting Workshop 2. Starting from this video, we will be discussing machine learning topics using the Python programming language. As I said early in this workshop series, these videos come from workshops that I ran for experienced professionals …

Hi, This is Part 4 of Workshop 1. We are continuing the discussion on the Pandas library. The code of this part is available below. We are starting from where we left in the last part. Here is the YouTube …

Welcome back. I am Dr. Shahriar Hossain. This is Part 3 of Data Science Workshop 1. In the previous part, we discussed NumPy. In this one, we will start to discuss Pandas. The Pandas library for Python is designed for …
