title: How to One Hot Encode categorical variables with a lot of unique values?
body: <p>I use Pandas for dataset exploration and I have a dataset of almost 10000 games, which includes columns like <em>Publisher, Developer, Rating</em> and so on.
  How do I encode columns such as <em>Publisher</em>, which has over 3000 unique values, without using LabelEncoding? If I use onehot enconding, count of my columns will explode, which is something that I'd like to avoid. Is there any way to encode that many values and still have reasonable amount of columns?</p>
