When training a machine learning model, machine learning engineers need to target and collect a large and representative sample of data. Data from the training set can be as varied as a corpus of text, a collection of images, sensor data, and data collected from individual users of a service. Overfitting is something to watch out for when training a machine learning model.
When you’re ready to get started with Machine learning tools it comes down to the Build vs. Buy Debate. If you have a data science and computer engineering background or are prepared to hire whole teams of coders and computer scientists, building your own with open-source libraries can produce great results. Building your own tools, however, can take months or years and cost in the tens of thousands.
Of course, if we allow the computer to keep splitting the data into smaller and smaller subsets (i.e., a deep tree), we might eventually end up with a scenario where each leaf node only contains one (or very few) data points. Therefore the maximum allowable depth is one of the most important hyperparameters when using tree-based methods. In this article, we’ll examine some of the algorithms used for classification … Read MoreView More Principal Component Analysis (PCA)
