A Tutorial on Machine Learning and Data Science Tools with Python

Abstract

In this tutorial, we will provide an introduction to the main Python software tools used for applying machine learning techniques to medical data. The focus will be on open-source software that is freely available and is cross platform. To aid the learning experience, a companion GitHub repository is available so that you can follow the examples contained in this paper interactively using Jupyter notebooks. The notebooks will be more exhaustive than what is contained in this chapter, and will focus on medical datasets and healthcare problems. Briefly, this tutorial will first introduce Python as a language, and then describe some of the lower level, general matrix and data structure packages that are popular in the machine learning and data science communities, such as NumPy and Pandas. From there, we will move to dedicated machine learning software, such as SciKit-Learn. Finally we will introduce the Keras deep learning and neural networks library. The emphasis of this paper is readability, with as little jargon used as possible. No previous experience with machine learning is assumed. We will use openly available medical datasets throughout.

Predicting Quality of Overnight Glycaemic Control in Type 1 Diabetes Using Binary Classifiers

“…The implementation of the models and their evaluation was done using the models and performance scores from the library Scikit-learn [35]. Moreover, the sampling techniques were used from the library Imbalanced-learn [36], data handling was done with Pandas [37] and data visualization using Matplotlib and Seaborn [38]. Finally, the statistical analysis was performed using Statsmodels [39].…”

Machine Learning and q-Weibull Applied to Reliability Analysis in Hydropower Sector

“…Several programming languages can be used in machine learning, each has its advantages and disadvantages over others (see [44]- [48] for details). Currently, hardware and technology have evolved in a specialized way to meet the implementation of learning machines [49], [50].…”

Developments in Transduction, Connectivity and AI/Machine Learning for Point-of-Care Testing

“…Several deep learning libraries are out there, supporting to build deep learning algorithms of considerable complexity. Particularly popular are, for instance, Tensorflow, Keras, Caffe, and Torch, mostly using Python [99]. Many practical recommendations are given in [100] for successfully and efficiently training and debugging large-scale and deep neural networks.…”
