Apache Spark is a Big Data cluster computing framework that can run on Standalone, Hadoop, Kubernetes, Mesos clusters, or in the cloud. We can read and write data from various data sources using Spark. For example, we can use CSV (comma-separated values), and TSV (tab-separated values) files as an input source to a Spark application.

We have discussed that how we can use Jupyter Lab/Jupyter Notebook to do Interactive Data Analysis with SQL Server using Jupyter Notebooks. Jupyter Notebook is a very powerful and useful tool for any Data Analyst/Data Scientist. The Jupyter Lab is the next generation tool for the Jupyter Notebooks. It provides an interface where we can

In this post, we are going to discuss the Relationship between Binomial and Poisson distributions. We know that Poisson distribution is a limit of Binomial distribution for a large n (number of trials) and small p (independent probability for each trial) values. A large number of trials n with very small probability p indicates a

Jupyter lab is the next-generation web-based UI experience for Jupyter notebook users. It facilitates a tab-based programming interface that is highly extensible and interactive. It supports 40+ programming languages. We have already discussed how we can use Jupyter notebooks for interactive data analysis with SQL Server. With the help of Jupyter notebooks, we can keep
In this post “Interactive Data Analysis with SQL Server using Jupyter Notebooks“, we will demonstrate how we can use Jupyter Notebooks for interactive data analysis with SQL Server. Jupyter notebooks are one of the most useful tools for any Data Scientist/Data Analyst. It supports 40+ programming languages and facilitates web-based interactive programming IDE. We can

Apache Spark is a general-purpose big data processing engine. It is a very powerful cluster computing framework which can run from a single cluster to thousands of clusters. It can run on clusters managed by Hadoop YARN, Apache Mesos, or by Spark’s standalone cluster manager itself. To read more on Spark Big data processing framework,

Once we have installed the Jupyter notebook, we can start it by executing “jupyter notebook” command in the command prompt on a Windows machine or in the terminal on a Mac machine. Jupyter notebook is a very useful web-based application which can be used to write programs in many programming languages like Python, R, Scala,

In this post “Python use case – Save each worksheet as a separate excel workbook“, we are going to learn that how we can create a separate workbook for each worksheet of a given excel file. We will be copying data, values, formatting and all other settings of the sheet in the newly created workbook.

In previous post, we created our first Machine Learning model using Logistic Regression to solve a classification problem. We used “Wisconsin Breast Cancer dataset” for demonstration purpose. Now, in this post “Building Decision Tree model in python from scratch – Step by step”, we will be using IRIS dataset which is a standard dataset that
