Adding Text Annotation to a Clustering Scatter Plot (tSNE) Introduction The tSNE (t-Distributed Stochastic Neighbor Embedding) algorithm is a popular dimensionality reduction technique used in various fields, including data visualization and clustering. One of the key challenges in visualizing high-dimensional data using tSNE is effectively communicating the underlying structure of the data. Adding text annotations to a clustering scatter plot can provide valuable insights into the relationships between different clusters and data points.

Calculating the Number of Months Between Two Dates in MS SQL Server MS SQL Server provides a variety of techniques to calculate the number of months between two dates. In this article, we will explore two common methods: using the LEAD function introduced in SQL Server 2012 and an older approach utilizing INNER JOIN, ROW_NUMBER, and date arithmetic. Introduction to MS SQL Server Date Functions Before diving into the specific solutions, it’s essential to understand some fundamental concepts related to dates in MS SQL Server:

Recoding Certain Values in R with the recode Function from Dplyr The recode function from the dplyr package provides a powerful way to modify values in a dataset. In this article, we’ll explore how to use the recode function to recode specific values in a dataset and keep others unchanged. Introduction In R, datasets are often used for data analysis, visualization, and modeling. When working with datasets, it’s common to need to modify or transform data in various ways.

Understanding Duplicate Rows in SQL Introduction When working with databases, it’s common to encounter duplicate rows that can be removed or handled in a specific way.
