    Python — One of the most powerful language

Developed in 1991, Python has been A poll that suggests over 57% of developers are more likely to pick Python over C++ as their programming language of choice for developing AI solutions. Being easy-to-learn, Python offers an easier entry into the world of AI development for programmers and data scientists alike.

With Python, you not only get excellent community support and an extensive set of libraries but also enjoy the flexibility provided by the programming language. Some of the features that you may benefit the most from Python are platform independence and extensive frameworks for Deep Learning and Machine Learning.

● Java

Write once, run anywhere

Java is considered one of the best programming languages in the world and the last 20 years of its use is proof of that.

With its high user-friendliness, flexible nature and platform independence, Java has been used for developing for AI in various ways, read on to know about some of them:

TensorFlow’s list of supported programming languages also includes Java with an API. The support isn’t as feature-rich as other fully supported languages, but it’s there and is being improved at a rapid pace.

Deep Java Library
Built by Amazon to create and deploy deep learning abilities using Java.

Kubeflow facilitates easy deployment and management of Machine Learning stacks on Kubernetes, providing ready to use ML solutions.

Apache’s OpenNLP is a machine learning tool for natural language processing.

Java Machine Learning Library
Java-ML provides developers with several machine learning algorithms.

Neuroph makes designing neural networks using the open-source framework of Java possible with the help of Neuroph GUI.

● R

R was created by Ross Ihaka and Robert Gentleman with the first version being launched in 1995. Currently being maintained by the R Development Core Team, R is the implementation of S programming language and aids in developing statistical software and data analysis.

The qualities that are making R a good fit for AI programming among developers are:

● The fundamental feature of R being good at crunching huge numbers puts it in a better position than Python with its comparatively unrefined NumPy package.

● With R, you can work on various paradigms of programming such as functional programming, vectorial computation and object-oriented programming.

Some of the AI programming packages available for R are:

● Gmodels provides a collection of several tools for model fitting

● Tm, as a framework for text mining applications

● RODBC as an ODBC interface for R

● OneR, for implementing One Rule Machine Learning classification algorithm, useful for machine learning models

Used widely among Data Miners and Statisticians, features provided by R are:

● Wide variety of libraries and packages to extend its functionalities

● Active and supportive community

● Able to work in tandem with C, C++ and Fortran

● Several packages help extend the functionalities

● Support for producing high-quality graphs

● Prolog

Short for Logic Programming, Prolog first showed up in 1972. It makes for an exciting tool for developing Artificial Intelligence, specifically Natural Language Processing. Prolog works best for creating chatbots, ELIZA was the first-ever chatbot created with Prolog to have ever existed.
ELIZA — The first-ever chatbot created with Prolog

To understand Prolog, you must familiarize yourself with some of the fundamental terms of Prolog’s that guide it’s working, they are explained in brief below:

● Facts define the true statements

● Rules define the statement but with additional conditions

● Goals define where the submitted statements stand according to the knowledgebase

● Queries define the how of making your statement true and the final analysis of facts and rules

Prolog offers two approaches for implementing AI that has been in practice for a long time and is well-known among data scientists and researchers:

● The Symbolic Approach includes rule-based expert systems, theorem provers, constraint-based approaches.

● The Statistical approach includes neural nets, data mining, machine learning and several others.

Lisp code to create an n-inputs m-units one layer perceptron

Short for List Processing, it is the second oldest programming language next to Fortran. Called as one of the Founding Fathers of AI, Lisp was created by John McCarthy in 1958.

Built as a practical mathematical notation for programs, Lisp soon became the choice of AI programming language for developers very quickly. Below are some of the Lisp features that make it one of the best options for AI projects on Machine Learning:

● Rapid Prototyping

● Dynamic Object Creation

● Garbage Collection

● Flexibility

With major improvements in other competing programming languages, several features specific to Lisp have made their way into other languages. Some of the notable projects that involved Lisp at some point in time are Reddit, HackerNews and Morioh

● Haskell

Defined in 1990 and named after the famous mathematician Haskell Brooks Curry, Haskell is a purely functional and statically typed programming language, paired with lazy evaluation and shorter code.

It is considered a very safe programming language as it tends to offer more flexibility in terms of handling errors as they happen so rarely in Haskell compared to other programming languages. Even if they do occur, a majority of the non-syntactical errors are caught at compile-time instead of runtime. Some of the features offered by Haskell are:

● Strong abstraction capabilities

● Built-in memory management

● Code reusability

● Easy to understand

Its features help improve the productivity of the programmer. Haskell is a lot like the other programming languages, just used by a niche group of developers. Putting the challenges aside, Haskell can prove to be just as good as other competing languages for AI with increased adoption by the developer community.

● Julia

Julia is a high-performance and general-purpose dynamic programming language tailored to create almost any application but is highly suited for numerical analysis and computational science. Various tools available for working with Julia are:

● Popular editors such as Vim and Emacs

● IDEs such as Juno and Visual Studio
Julia source code organization

Some of the several features offered by Julia that make it a noteworthy option for AI programming, Machine Learning, statistics, and data modeling are:

● Dynamic type system

● Built-in package manager

● Able to work for parallel and distributed computing

● Macros and metaprogramming abilities

● Support for Multiple dispatches

● Direct support for C functions

Built to eliminate the weaknesses of other programming languages, Julia can also be used for Machine Learning applications with integrations with tools such as TensorFlow.jl, MLBase.jl, MXNet.jl and many more that utilize the scalability provided by Julia.
