The Spark framework, written in Scala, has become a de facto standard for distributed computing and big data processing. Scala’s interoperability with Java allows for leveraging Java libraries while benefiting from Scala’s expressive syntax.


C++ may not be the most popular choice for machine learning languages, but it remains a vital language for high-performance computing and systems-level programming. C++’s low-level control and efficient memory management make it suitable for resource-intensive tasks in machine learning. Libraries like TensorFlow and OpenCV provide C++ bindings, allowing for efficient implementation of machine learning algorithms. C++’s speed and versatility make it an excellent option for embedded systems and real-time applications.


TensorFlow, developed by Google, has become a dominant force in the field of machine learning. This machine learning language has an open-source library that provides a comprehensive platform for building and deploying deep learning models. TensorFlow’s flexibility and scalability make it suitable for a wide range of applications, from computer vision to natural language processing. Its intuitive high-level API, TensorFlow 2.0, simplifies the development process, while its lower-level APIs allow for fine-grained control and customization. TensorFlow’s extensive ecosystem includes tools like TensorFlow Extended (TFX) for production pipelines, TensorFlow Probability for probabilistic modelling, and TensorFlow Lite for deploying models on resource-constrained devices. With its widespread adoption and continuous development, TensorFlow remains a crucial language for machine learning practitioners.


With its rich set of toolboxes and libraries, MATLAB offers comprehensive support for machine learning tasks. This Statistics and Machine Learning Language Toolbox provides a wide range of algorithms for classification, regression, clustering, and dimensionality reduction. MATLAB’s user-friendly interface and interactive environment make it suitable for rapid prototyping and experimentation. Additionally, MATLAB’s integration with Simulink allows for seamless development of machine learning models in control systems and robotics. While MATLAB may not be as widely adopted as Python or R in machine learning languages, its extensive functionality and ease of use make it a valuable language for academic research and certain industry applications.


Go, also known as Golang, has gained popularity in recent years as a language suitable for concurrent programming and system-level development. Although not traditionally associated with machine learning languages, Go offers libraries and frameworks that make it a viable option for building scalable and efficient machine learning languages. Libraries like Gorgonia and TensorFlow-Go provide bindings to popular machine learning libraries, allowing Go developers to leverage existing models and algorithms. Go’s simplicity, strong typing, and efficient execution make it particularly well-suited for deploying machine learning models in production environments. Furthermore, Go’s built-in concurrency support and lightweight goroutines enable efficient parallelization of machine learning tasks. While still emerging in the machine learning space, Go offers a unique blend of performance and simplicity that appeals to developers seeking a language with strong system-level capabilities.


Initially designed as a language for iOS and macOS app development, Swift has now made its way into machine learning languages. Swift’s modern syntax, safety features, and growing ecosystem make it an attractive choice for developers looking to integrate machine learning languages into their iOS applications. Apple’s Core ML framework provides seamless integration of trained machine learning languages into Swift-based applications. Core ML supports various model formats, including TensorFlow and ONNX, allowing for easy integration with models trained in other languages. Swift for TensorFlow (S4TF) is another notable project that brings the power of Swift to machine learning, enabling developers to build and train models using Swift syntax. With the rise of mobile and edge computing, Swift’s presence in the machine learning landscape is expected to grow, making it a language worth exploring for iOS and macOS developers interested in AI.


Perl, a high-level scripting language, has a long-standing history in the field of text processing and data manipulation. Although less popular than Python or R for machine learning languages, Perl offers a range of libraries and modules that can be leveraged for building machine learning applications. CPAN (Comprehensive Perl Archive Network) provides a vast collection of modules for data preprocessing, statistical analysis, and machine learning algorithms. Popular modules like Algorithm::LibLinear and Algorithm::SVM offer support for training support vector machines and other classification models. Perl’s regular expression capabilities also make it a suitable language for natural language processing tasks. While Perl may not be the first choice for newcomers to machine learning, its strengths in text processing and data manipulation make it a valuable tool for certain specialised applications, particularly in domains where Perl is already established.


JavaScript, the ubiquitous language for web development, has also found its way into the machine learning realm.
