Applying Wrapper Methods in Python for Feature Selection

Introduction In the previous article, we studied how we can use filter methods for feature selection for machine learning algorithms. Filter methods are handy when you want to select a generic set of features for all the machine learning models. However, in some scenarios, you may want to use a specific machine learning algorithm to train your model. In such cases, features selected through filter methods may not be the most optimal set of features for that specific algorithm. There […]

How to Create, Move, and Delete Files in Python

Introduction Handling files is an entry-level and fundamental skill for any programmer. They’re very commonly used to store application data, user configurations, videos, images, etc. There are a countless number of use-cases for files in software applications, so you’d be smart to make yourself deeply familiar with the tasks of manipulating files. These tasks could include (among others) creating, deleting, and moving files. In this article, we’ll cover the process of working with files using the Python programming language. The […]

Python GUI Development with Tkinter: Part 3

This is the third installment of our multi-part series on developing GUIs in Python using Tkinter. Check out the links below for the other parts to this series: Introduction Tkinter is the de facto standard package for building GUIs in Python. In StackAbuse’s first and second part of the Tkinter tutorial, we learned how to use the basic GUI building blocks to create simple interfaces. In the last part of our tutorial, we’ll take a look at a couple of […]

Time Series Analysis with LSTM using Python’s Keras Library

Introduction Time series analysis refers to the analysis of change in the trend of the data over a period of time. Time series analysis has a variety of applications. One such application is the prediction of the future value of an item based on its past values. Future stock price prediction is probably the best example of such an application. In this article, we will see how we can perform time series analysis with the help of a recurrent neural […]

Lists vs Tuples in Python

Introduction Lists and tuples are two of the most commonly used data structures in Python, with dictionary being the third. Lists and tuples have many similarities. Some of them have been enlisted below: They are both sequence data types that store a collection of items They can store items of any data type And any item is accessible via its index. So the question we’re trying to answer here is, how are they different? And if there is no difference […]
