Working with the Python Machine Learning Library - Scikit-learn
Scikit-learn is a powerful machine learning library that provides a wide variety of modules for data access, data preparation and statistical model building. It has a good selection of clean toy datasets that are great for people just getting started with data analysis and machine learning. Easy access to these data sets removes the hassle of searching for and downloading files from an external data source. The library also enables data processing tasks such as imputation, data standardization and data normalization. These tasks can often lead to significant improvements in model performance.
Scikit-learn also provides a variety of packages for building linear models, tree-based models, clustering models and much more. It provides an easy-to-use interface for each model object type, which facilitates fast prototyping and experimentation with models. Beginners in machine learning will also find the library useful since each model object is equipped with default parameters that provide baseline performance. Overall, Scikit-learn provides many easy-to-use modules and methods for accessing and processing data and building machine learning models in Python. This tutorial will serve as an introduction to some of its functions.

Amilestone for open source projects — French President Emmanuel Macron has recently been introduced to Scikit-learn. In fact, in a recent tweet, Scikit-learn creator and Inria tenured research director, Gael Varoquaux announced the presentation of Scikit-Learn, with applications of machine learning in digital health, to the president of France.
He stated the advancement of this free software machine learning library — “started from the grassroots, built by a community, we are powering digital revolutions, adding transparency and independence.”

Undoubtedly, Scikit-learn is one of the best machine learning libraries available today. There are several reasons for that. The consistency among Scikit-learn estimators is one reason. You cannot find such consistency in any other machine learning library. The .fit()/.predict() paradigm best describes the consistency. Another reason is that Scikit-learn has a variety of uses. It can be used for classification, regression, clustering, dimensionality reduction, anomaly detection.
Therefore, Scikit-learn is a must-have Python library in your data science toolkit. But, learning to use Scikit-learn is not straightforward. It’s not simple as you imagine. You have to set up some background before learning it. Even while you learning Scikit-learn, you should follow some guidelines and best practices. In this article, I’m happy to share 9 guidelines that worked for me to master the Scikit-learn without giving up the learning process in the middle. Whenever possible, I will include the links to my previous posts which will help you to set up the background and continue to learn the Scikit-learn.

If you have just taken your first step in the data science industry and are learning the Python programming language then, being a Pythonist, you should be aware of the Scikit-learn library. If you are seriously considering bringing data science and machine learning into a productive system, then you should be comprehensive for the Scikit-learn Python library. In this article, let us explore the Scikit-Learn Python library and learn different aspects of its utilization.
Scikit-learn is also known with the synonyms like scikits.learn (previously known) or sklearn. It is a free and open-source machine learning library that is used for the Python programming language. The library was developed by David Cournapeau as a Google Summer Code project in 2007. The project was later joined by Matthieu Brucher in 2010. The library was first made public in February 2010, and in just two years, that is, in November 2012, the library became one of the most popular libraries of machine learning on Github. The primary features of the Scikit-learn library include classification, regression, and clustering algorithms (support vector machines, random forests, gradient boosting, k-means, and DBSCAN). The sklearn is designed to deal with numerical and scientific libraries of Python like NumPy and SciPy.
Sklearn is utilized majorly in Python programming language and NumPy is used to extend its high-performance in linear algebra and operations. Some of the core algorithms that are written in Cython also use this library to improvise the performance.

Recently, researchers from Google proposed the solution of a very fundamental question in the machine learning community — What is being transferred in Transfer Learning? They explained various tools and analyses to address the fundamental question.
The ability to transfer the domain knowledge of one machine in which it is trained on to another where the data is usually scarce is one of the desired capabilities for machines. Researchers around the globe have been using transfer learning in various deep learning applications, including object detection, image classification, medical imaging tasks, among others.
