FinOps 101: What is FinOps? (2025)
Cloud computing gives you on-demand access to computing resources—ranging from storage and processing power to fully managed services—without the need to invest in or maintain your own physical hardware. You can cut massive costs, eliminate maintenance headaches, and scale your services quickly with on-demand resources. Many companies and organizations are making the switch to cloud services to cut…
Google Cloud Dataproc vs Databricks: 7 Differences to Know (2025)
Say you’re dealing with data—tons of it. Maybe you’re processing logs, training ML models, or running analytics. Whatever it is, you need a platform that can handle the load without making your life harder. There are many options available, but two that you might consider are Google Cloud Dataproc and Databricks. Databricks is a unified analytics platform built on Apache Spark that brings data…
Apache Spark with Python 101—Quick Start to PySpark (2025)
Apache Spark is an open source, distributed engine for large-scale data processing. It was developed at UC Berkeley’s AMPLab in 2009 (and released publicly in 2010), mainly to address the limitations of Hadoop MapReduce—particularly for iterative algorithms and interactive data analysis. Spark executes programs significantly faster—up to 100x quicker than Hadoop MapReduce in certain workloads—primarily due to its in-memory processing capabilities. Plus,…
Understanding the Confusion Matrix in Machine Learning
In machine learning, particularly in the field of classification, the confusion matrix is a useful tool for evaluating the performance of a binary classifier.
Understanding the Bias-Variance Trade-Off in Machine Learning
What is Bias-Variance Trade-Off? In the world of machine learning, the bias-variance trade-off is one of the most crucial concepts for building a successful model. It represents the delicate balance between two types of errors that can influence the performance of a model: bias and variance. These two sources of error can be thought of…
Understanding Selection Bias in Research: Types, Causes, and Impact
What is Selection Bias? Selection bias is a type of error that arises in research when the participants or data selected for study are not representative of the population as a whole. In simple terms, it occurs when researchers make non-random decisions about who or what to include in their study, which leads to conclusions…
What is Data Science? Understanding the Differences Between Supervised and Unsupervised Learning
What is Data Science? Data Science is an interdisciplinary field that blends various tools, algorithms, machine learning principles, and statistical techniques with the ultimate goal of extracting valuable insights from raw data. The primary focus of data science is to analyze large and complex data sets to uncover patterns, trends, and relationships that can…
Exploring Non-Gaussian Data Sets: Understanding Binomial, Poisson, and More
What is an Example of a Data Set with a Non-Gaussian Distribution? In the world of machine learning and statistics, the Gaussian distribution (also known as the normal distribution) is one of the most commonly used distributions. This distribution is often assumed for many algorithms because it has nice mathematical properties, such as being symmetric…
Understanding Selection Bias: How It Impacts Data Analysis and Modeling
What is Selection Bias and How Does It Affect Data Analysis? In data analysis and machine learning, one of the most significant challenges is ensuring that the data used for training models is representative of the population or real-world scenarios the model will encounter in the future. If the data is skewed, incomplete, or unrepresentative,…
Understanding Statistical Interaction in Research
What is a Statistical Interaction? In research and statistical modeling, understanding how independent variables affect a dependent variable is key to drawing meaningful conclusions. However, the effect of one independent variable on the dependent variable can be more complex when other independent variables are involved. This complexity is referred to as statistical interaction. A statistical…
