We use jupyter notebooks in classes and it is always nice to see how Jermey&rsquo;s notebook looks.</p> <p>It has few tweaks like</p> <ul> <li>collapsible headings</li> <li>better tables and fonts</li> </ul> <p>Learnt that he uses a themes for the visual customizations and an extensions to allow collapsing of headers from his reply in <a href="http://forums.fast.ai/t/collapsable-expandable-jupyter-cells/205/5">forums</a></p> <p>The theme script can be installed from <a href="https://github.com/dunovank/jupyter-themes">jupyter-themes repo</a></p>https://www.tutysara.net/posts/2018/01/07/use-skipgrams-with-sklearn-countvectorizer-and-tfidfvectorizer/Sun, 07 Jan 2018 00:00:00 +0000https://www.tutysara.net/posts/2018/01/07/use-skipgrams-with-sklearn-countvectorizer-and-tfidfvectorizer/<p>We don&rsquo;t have an implementation for skipgrams in sklearn. This post covers how to use the skipgram function in <code>nltk</code> with sklearn&rsquo;s CountVectorizer and TfidfVectorizer</p> <p>We are going to create a skipgram tokenizer that can be passed to the <code>tokenizer</code> parameter of the vectorizer.</p> <p>Create a basic tokenizer that can split the original strings to tokesn. Tokenizer can be just <code>.split()</code> or a function to filter non-alpahbets etc. We can use tokenizer as below</p>
