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 […]

You are probably using machine learning a number of times in a day without even noticing. For instance, whenever you check your mail box, a spam filter saves you from going through spam messages. And that is because it has learned how to distinguish between spam and non-spam mails. That is Machine Learning (ML). To […]

Principal component analysis, or PCA, is a powerful tool which is used to analyze data sets and is formulated in the language of linear algebra and statistics. It is an eigenvalue method used to reduce the dimension of a data set while preserving important information. Suppose we have individuals and we measure the same m […]

Just about everyone has watched animated movies such as Frozen or Big Hero 6 or has at least heard about 3D computer games. It seems more fun to enjoy the movies and games rather than reading a Linear Algebra book. But it is because of linear algebra that we are able to watch a character […]

Data is key for making important business decisions. Depending upon the domain and complexity of the business, there can be many different purposes that a regression model can solve. It could be to optimize a business goal or find patterns that cannot be observed easily in raw data. Even if you have a fair understanding […]

In the previous article, we saw how dplyr and tidyr packages in R can be used to visualize and plot data to gain a better understanding of the underlying properties. Now let’s explore the data visualization techniques in Python and see how similar tasks can be performed. Pandas: Pandas is a Python package aimed toward […]
