1- The need for a good language
Standard expertise in and familiarity with a robust programming language is almost imperative for machine learning professionals. Unless you’re a researcher working purely on some complex algorithm, you’re expected to use the existing machine learning algorithms mostly and apply them in resolving problems. And this requires a programming hat for you to put on.
2- The equation between machine learning and Python
Apart from enjoying huge popularity in different areas of software development, Python has obtained a leading position in the machine learning domain today. The combination of simplicity, shorter development time, and consistent syntax make Python well-suited for projects in the field of machine learning. Let’s take a deeper look into these factors.
3- Extensive set of libraries
Libraries refer to sets of functions and routines, which are written in a given language. A solid set of libraries eliminates the need for developers to rewrite many lines of code when performing complex tasks. As machine learning largely encompasses mathematical optimization, probability, and statistics, extensive Python libraries help mathematicians/researchers to perform study easily.
Here’re some of the most commonly used fundamental Python libraries in machine learning.
- Pandas: Developed upon a NumPy (Numerical Python) array, Pandas offers fast execution speed and various data engineering features. This is the most popular library in the Python ecosystem for performing general-purpose data analysis. Some of its data engineering features include finding and filling missing data, selecting subsets of data, combing multiple datasets together, reshaping data into different forms, reading/writing different data formats, as well as calculating down columns and across rows, among others.
- NumPy: It’s the fundamental package needed for high-performance data analysis and scientific computing in the Python ecosystem. Higher-level tools like scikit-learn and Pandas are developed based on this foundation. Having many NumPy operations implemented in C, the package is absolutely fast, which is an invaluable advantage for today’s machine learning
- Scikit-learn: One of the most popular machine learning libraries, scikit-learn supports an array of supervised as well as unsupervised algorithms like decision trees, linear and logistic regression, k-means, and clustering, among others. Two fundamental libraries of Python namely NumPy and SciPy are the basis of Scikit-learn. It makes implementation of tasks like feature selection, transforming data, ensemble methods etc possible within a few lines.
- Seaborn and Matplotlib: Both data visualization and storytelling are critical for any machine learning professional as they often need to carry out an exploratory analysis of datasets before deciding to apply a specific machine learning algorithm. Seaborn is an excellent visualization library aimed at statistical plotting. On top of Matplotlib, it offers an API together with defining simple high-level functions for general statistical plot types. It also integrates with functionality offered by Pandas. Matplotlib is the most commonly used 2D Python visualization library. Presence of a great array of interfaces and commands allows professionals to develop publication-quality graphics from the data.
Python is highly acclaimed for its readable, concise code. It’s perhaps the best when it comes to simplicity and ease of use, especially for novice developers. Multi-stage workflows and extremely complex algorithms are two pillars of machine learning, and less intricacies of coding allow professionals to focus more on finding solutions to problems, and attaining the goals of a project.
In addition, when it comes to collaborative coding or machine learning projects changing hands between teams, easy readability of codes plays a hugely advantageous role in business life. It becomes even more important if the project comes with a great deal of third-party components or custom business logic. Simple syntax of Python helps in faster development compared to many other programming languages, allowing the developers to test algorithms quickly without having to implement them.
I wrote about that here.
5- Great support
Python is completely open source and is supported by a great community. It offers a great array of resources that are capable of enabling developers to work faster. In addition, presence of a huge and active community of developers can help in any and every single stage of a development cycle.
Flexibility is another core advantage offered by Python. Additionally, it’s perfect for linking different data structures and works as an ideal backend. A majority of code can also be checked in the IDE, especially for developers who’re struggling between different algorithms.
7- Less amount of code
Machine learning hugely encompasses algorithms, and Python makes it simpler for developers in testing. It comes with the potential of implementing the same logic with as less as one-fifth of code required in other OOP (object-oriented programming) languages. In addition, Python’s integrated approach lets developers to check code methodology.
These are the key factors that smoothen the working process, making Python one of the hottest languages today.
