Integrated Development Environment (IDE) An integrated development environment is an application which provides programmers and developers with basic tools to write and test software. In general, an IDE consists of an editor, a compiler (or interpreter), and a debugger which can be accessed through a graphic user interface(GUI). According to Wikipedia, “Python is a widely used […]

Introduction Last week, we learned about Random Forest Algorithm. Now we know it helps us reduce a model's variance by building models on resampled data and thereby increases its generalization capability. Good! Now, you might be wondering, what to do next for increasing a model's prediction accuracy ? After all, an ideal model is one […]

Is it gonna rain today? Should I take my umbrella to the office or not? To know the answer to such questions we will just take out our phone and check the weather forecast. How is this done? There are computer models which use statistics to compare weather conditions from the past with the current […]

Times are changing and have been for a while now. In the world of STEM, women are no longer considered a “bad fit,” which is easily proved by the amazing number of brilliant women in the field today. Women are just as interested in finding out how things work, extracting insight from data, problem-solving, and […]

Introduction Treat "forests" well. Not for the sake of nature, but for solving problems too! Random Forest is one of the most versatile machine learning algorithms available today. With its built-in ensembling capacity, the task of building a decent generalized model (on any dataset) gets much easier. However, I've seen people using random forest as a […]

Introduction "The road to machine learning starts with Regression. Are you ready?" If you are aspiring to become a data scientist, regression is the first algorithm you need to learn master. Not just to clear job interviews, but to solve real world problems. Till today, a lot of consultancy firms continue to use regression techniques […]

What is NLP? If you walk to an intersection of computational linguistics, artificial intelligence, and computer science, you are more than likely to see Natural Language Processing (NLP) there as well. This is what Wikipedia says. NLP involves computers processing natural language—human-generated language and not math or Java or C++. You’ve already seen these famous […]

Machine Learning In very simple terms, Machine Learning is about training or teaching computers to take decisions or actions without explicitly programming them. For example, whenever you read a tweet or movie review, you can figure out if the views expressed are positive or negative, but, can you teach a computer to determine the sentiment […]
