String matching made simple — Data scientists have to deal with all sorts of data during their day-to-day tasks. One of the biggest challenges to data processing comes with unstructured data. Data is called unstructured when it can not be represented in a tabular (structured) manner. Unstructured data includes text, audio, video files, etc. Text…

And maybe build one… — A smart contract is essentially a set of legal rules. Just like a legal contract defines proceedings of a certain transaction or event in legal terms, a smart contract defines what rules transactions will follow on decentralized applications (Dapps). …

Blockchain, cryptocurrency, mining, decentralization, and more… — Blockchain technology has been around for about a decade now. It started with the advent of the great Bitcoin back in 2009 by Satoshi Nakamoto. Ever since then Blockchain, Cryptocurrency as Web3 have been getting a lot of hype, and today (In 2022) these are all that everyone talks about. …

Implementation and explanation from scratch — This article aims to explain, the very popular, Boruta feature selection algorithm. Boruta automates the process of feature selection as it automatically determines any thresholds and returns features that are most meaningful in your dataset. Boruta works on the “all-relevant” principle as it provides you with ALL the features that…

Choosing the right ones — Feature Selection is an optional, yet important preprocessing step for your Machine Learning model. It is a common practice to feed your Machine Learning model data as you receive it. This is a very common rookie mistake, data that you receive from whatever source will always contain errors. There are…

Naive Bayes is a Machine Learning Classifier that is based on the Bayes Theoram of conditional probability. In this article, we will be understanding conditional probability (Bayes Theoram) and then moving on to how it translates to the Naive Byes classifier. …

Data Science is a very important skill that has become a necessity of the 21st century. With the increase in data, the need for data scientists has increased. When it comes to learning Data Science, Python is the go-to programming language. Python comes with a plethora of tools that aid…

When working with data we rarely come across clean and processed data. Before this data can be used anywhere, we need to apply a lot of processing to it in order to make it of any use. One of these techniques is pattern matching in strings to keep only the…

With the developments in Artificial Intelligence and data gaining more and more power, Python is becoming increasingly relevant. It won’t be wrong to say that Python is the most popular programming language in current times. …
