Write cleaner, leaner JavaScript and Julia, and master feature engineering

[Packt]( [$5 Sale]( While much of the last decade can be characterized by the framework boom, in recent years there’s been an increasing awareness of understanding the fundamentals of languages. Two of our new release titles this week tap into that trend, offering new perspectives on how to think about and use JavaScript and Julia. Feature engineering isn’t that different in spirit from this – with a growing awareness of the complexities and unintended consequences of poorly built algorithms, paying close attention to the features used in models is now a priority for engineers – we're exploring it in depth with Python Feature Engineering Cookbook. [Shop all New Releases for $5]( New Releases just added to the $5 sale [Product Cover]( [Python Feature Engineering Cookbook]( Extract accurate information from data to train and improve machine learning models using NumPy, SciPy, pandas, and scikit-learn libraries. RRP $20.99  $5.00 [Add to Cart]( Feature engineering is an integral part of machine learning. Although data set size and processing speed might attract the most attention when it comes to many discussions around modern machine learning, without effective and thoughtful feature engineering your models could be useless - or worse. In Python Feature Engineering Cookbook you’ll find a diverse range of recipes covering key issues in feature engineering. This includes content on Python feature engineering libraries and frameworks such as Feature-engine and Featuretools.
