In this Data Science in Minutes, we will describe what time series forecasting is, and provide several examples of when you can use time series for your data. Time Series is looking at data over time to forecast or predict …
In this quick overview, we introduce you to the concepts of one-versus-one and one-versus-all in classification. In classification models, you will often want to predict one class from another. This is called binary classification, or one-versus-one. But what if you …
In this quick tutorial, we learn that machines can not only make sense of words but also make sense of words in their context. N-grams are one way to help machines understand a word in its context by looking at …
In this quick tutorial, we go over the basics of Natural Language Processing, what it is, and a few key applications of it. Machines can’t simply read and interpret language innately like we humans can. So how can machines understand …
We will look at the fundamental concept of clustering, different types of clustering methods and the weaknesses. Clustering is an unsupervised learning technique that consists of grouping data points and creating partitions based on similarity. The ultimate goal is to …
You may have come across the terms “Precision, Recall and F1” when reading about Classification Models and machine learning. In this Data Science in Minutes tutorial, we will explain what Precision, Recall and F1 are, and when you can use …
A confusion matrix, also known as an error matrix, uses a special table to help visualize the performance of your classification model. That way, you can easily see how successful your model was when predicting the class. In this introduction, …
Ever wonder what classification models do? In this quick introduction, we talk about what classifications models are, as well as what they are used for in machine learning. In machine learning there are many different types of models, all with …
In this tutorial we go over what you need for steps in online experimentation. When running a business, there are many different moving parts happening all at once. This is why it is helpful to carefully draw out your steps …
So, we’ve just covered what is an A/B test and what is a multivariate test, but what is an A/A test? In this quick tutorial we go over A/A testing, what it is and how to use it to help …
