Deep learning is a type of machine learning that’s growing at an almost frightening pace. Nearly every projection has the deep learning industry expanding massively over the next decade. This market research report, for example, expects deep learning to grow 71x in the US and more than that globally over the next ten years. There’s […]
One of the reasons that R is a top language for data science is that it’s great for data visualization. R users can take advantage of the wildly popular ggplot2 package to turn massive data sets into easily-readable charts in just a few lines of code. That can be incredibly valuable for presenting your data, […]
One of the most difficult parts of learning anything (including data science) is staying motivated. At first, we’re excited about our new studies, and we progress quickly through the basics. But over time, as the work gets more challenging and other problems and pressures arise in our lives, it gets easier and easier to fall […]
