CatBoost Part 1: Ordered Target Encoding StatQuest with Josh Starmer 2023-02-27 | One of the defining features of CatBoost is its concerted effort to avoid data leakage at all costs. In this video, we'll see how it eliminates a potential threat in Target Encoding by ordering the data and encoding it sequentially. This ordered approach is central to everything CatBoost does and we'll see it again in Part 2 when we talk about how it builds trees.NOTE: This StatQuest is based on the original CatBoost manuscript... arxiv.org/abs/1706.09516...and an example provided in the CatBoost documentation...catboost.ai/en/docs/concepts/algorithm-main-stages_cat-to-numbericEnglishThis video has been dubbed using an artificial voice via aloud.area120.google.com to increase accessibility.

One-Hot, Label, Target and K-Fold Target Encoding, Clearly Explained!!! StatQuest with Josh Starmer 2023-02-13 | In theory, discrete variables, or features, are easy to use with machine learning algorithms. However, in practice, it's not always so easy and we often have to transform discrete values, like favorite colors, into numbers. There are lots of ways to do this, and this video walks you through 3 of the most popular methods.EnglishThis video has been dubbed using an artificial voice via aloud.area120.google.com to increase accessibility.

Long Short-Term Memory (LSTM), Clearly Explained StatQuest with Josh Starmer 2022-11-07 | Basic recurrent neural networks are great, because they can handle different amounts of sequential data, but even relatively small sequences of data can make them difficult to train. This is where Long Short-Term Memory (LSTM) saves the day. Long Short-Term Memory is a type of recurrent neural network that can handle much larger sequences of data without those pesky exploding/vanishing gradient problems that plague basic recurrent neural networks.SpanishEste video ha sido doblado al español con voz artificial con aloud.area120.google.com para aumentar la accesibilidad.

StatQuest with Josh Starmer 2022-10-05 | A lot of machine learning algorithms can not deal with categorical data (like "favorite color" or "country code") directly. As a result, we have translate them into some sort of numerical value. The most common practice is to use something called One-Hot-Encoding, which is fine if you don't have many options for each category. However, if you have a lot of options, things get out of hand quickly. This is where methods like Target Encoding really start to shine, so that's what we'll talk about today.
