A Guide to the Most Popular Machine Learning Frameworks, Libraries, Tools & Languages

by | Mar 1, 2024

Machine learning (ML) is becoming an integral part of many applications we use in our daily lives (from ChatGPT to Self-driving cars). This makes it imperative to understand and know how to apply machine learning. This comprehensive guide will delve into the most popular programming languages, frameworks, libraries, and tools that form the backbone of the ML ecosystem, providing insights into their strengths and how they interconnect to facilitate the creation of cutting-edge ML applications.

Introduction to Machine Learning

Machine learning, a branch of artificial intelligence, involves training computers to learn from data, make predictions, and improve their decision-making processes over time without being explicitly programmed. From voice recognition systems and customer service chatbots to predictive data analytics in healthcare and finance, machine learning is changing how we interact with data and technology. Central to this revolution are the languages, libraries, frameworks, and tools designed to streamline the development and deployment of machine learning models.

Most Popular Machine Learning Languages

Programming languages are the foundation upon which software is built, offering a syntax and set of rules for instructing computers to perform various tasks. In the context of machine learning, the choice of programming language can significantly impact the ease of development, model performance, and scalability.

Choosing the right language for a machine learning project involves considering the specific requirements of the project, the language’s performance, and its ecosystem. Python offers a broad range of libraries and ease of use, R provides advanced statistical functions, while Julia offers superior performance for numerical computations.

Python Programming Language

Python is an ideal language choice for machine learning, data science, and artificial intelligence (AI). It has been ranked top in the IEEE Spectrum’s annual list of popular programming languages and its continued rise in use over the past five years according to Stack Overflow trends.

The secret to Python’s dominance in the machine learning sphere lies in its comprehensive library

ecosystem. This ecosystem enables practitioners to efficiently handle, process, and transform data, significantly reducing the development time for complex machine learning models. Libraries such as TensorFlow, PyTorch, and Scikit-learn provide foundational code, meaning that engineers can focus on developing solutions rather than building everything from scratch. The simplicity of Python’s syntax and its emphasis on readability foster a collaborative environment where ideas, algorithms, and tools can be easily shared among peers.

Python’s flexibility is another key advantage. Other than being used in machine learning, Python can also be used in building web applications. This adaptability, combined with Python’s extensive libraries, minimises the likelihood of errors and streamlines the implementation of changes without the need for recompilation.

R Language

R is designed by statisticians for statisticians, making it a powerhouse for statistical analysis and data visualisation. Its strength lies in an extensive array of packages that facilitate the training and evaluation of machine learning algorithms. As an open-source language, R provides a cost-effective solution for projects of any size and supports matrix arithmetic and data structures.

R’s comprehensive suite of machine learning techniques covers everything from data visualisation to supervised and unsupervised learning, making it a formidable choice for projects that require deep statistical analysis. Its programming style is not difficult to learn, while its flexibility and cross-platform compatibility allow practitioners to utilise the best tools for each task, enhancing the overall workflow.

Julia Language

Julia is gaining traction as a high-performance, general-purpose language, challenging Python and R in machine learning applications. Its design caters specifically to high-performance numerical analysis and computational science, making it ideal for applications requiring intensive mathematical computations.

Julia’s compatibility with hardware across all clouds and its ability to be compiled natively from other languages enhance its appeal for complex machine learning tasks. Key features such as Just-in-Time compilation via the LLVM framework and universal executability position Julia as a strong candidate for scalable machine learning solutions. 

Most Popular Frameworks for Machine Learning

Frameworks in machine learning offer predefined structures and functions to streamline the development of machine learning models, covering tasks from data preprocessing to model evaluation.

Selecting a machine learning framework involves evaluating factors such as the specific needs of the project, the framework’s performance, ease of use, community support, and how well it integrates with other tools and technologies.

Here are some of the most popular frameworks currently used by practitioners.

Apache Spark MLlib

Apache Spark MLlib is one of the key platforms for big data processing in machine learning. Built atop Apache Spark, an open-source cluster computing framework, Spark MLlib offers advanced APIs optimised for machine learning tasks such as classification, regression, and clustering. The key to Spark MLlib’s success lies in its unmatched ability to handle vast datasets in tandem, enabling parallel processing that ensures both speed and efficiency.

Spark MLlib’s appeal extends beyond its scalability and performance; it is celebrated for its ease of integration with a wide array of data sources and analytical tools. This seamless connectivity allows practitioners to effortlessly combine Spark MLlib with their existing data pipelines, making it an invaluable asset for projects requiring the manipulation and analysis of large-scale data.

XGBoost

XGBoost, or eXtreme Gradient Boosting, has carved a niche for itself as a leading machine learning framework for structured data analysis. Praised for its efficiency and performance, XGBoost leverages the gradient boosting algorithm to enhance model accuracy iteratively. Its use of regularisation techniques helps in preventing overfitting, thereby improving the model’s generalisation to new data.

One of the standout features of XGBoost is its parallel processing capability, which, when combined with its sophisticated tree pruning algorithm, not only speeds up the process, but also simplifies the resulting models for better interpretability and performance. This is also one of the key topic taught in our AI200: Applied Machine Learning course.

Fast.ai

Fast.ai emerges as a powerful machine learning framework for deep learning practitioners, built on the robust foundations of PyTorch. It distinguishes itself with a user-friendly interface and a library that can generate comprehensive training data to enhance model performance.

Fast.ai can be integrated with libraries such as PyTorch to build and train deep learning models and complex machine learning models. However, despite its ease of use, one of its drawbacks is that it may be difficult for beginners to pick up, has limited customisations, and contains many dependencies.
