What is the best programming language for artificial intelligence purposes?
Mind that using suggested language I must be able to employ any AI technique (or at least most of them).

It really depends on what kind of problem you are looking at. Also, how “deep” you want to go into AI stuff. If you want to learn from the basics and just implement theoretical AI stuff, go with a higher level language– as in functional programming (and proven in AI) like lisp, or prolog. If you know what problem set you are dealing with and want efficient, go with something like Java, C++ and use a toolkit to do the stuff.
Since you mention Machine Learning look into Weka Toolkit in Java for some of these stuff.
There is no “best” language. Each one has its merits. When I studied AI, mostly we worked with lisp and prolog, but I’ve been most productive in AI with Java/C# and F# has a lot to offer.
All the cool bearded gurus in what’s left of AI research use Lisp 🙂
There are two big camps: Common Lisp and Scheme. They have different syntax, etc. Lots of good stuff written for both.
Java is a very popular all-purpose language but a lot of the interesting stuff in AI / Functional Programming, such as passing closures as first-order objects, is clumsy to do in Java.
My personal preference would be to stay away from Windowsy languages like C# and F#. Cool people develop under Unix. Or Linux if they’re cool but poor.
Some cool but weird people program in Haskell. A reasonably modern FP language with good performance. I tried it once, it made my brain hurt; but you might be smarter than I am.
UPDATE: Answers to Steve’s questions.
I wouldn’t be the one paying for a Unix variant; that’s what corporations and research institutes do. The idea is, you want to be doing AI research for an outfit that sinks millions into their hardware and doesn’t balk at paying a few thousand for an operating system. That’s the kind of outfit likely to have good food in the cafeteria and/or pay well for doing fun work. But I’m certainly not knocking Linux.
F# may be cool but I see a whole raft of issues getting it to run on Linux or any other Unix (that’s what I meant by “windowsy”), and I don’t want to work under Windows (that’s what I meant by “personal preference”).
To elaborate on the “windowsy” theme: You mention that F# is an OCaml variant. From my own admittedly brief research, it seems that F# is missing functors, OCaml-style objects, polymorphic variants and the camlp4 preprocessor. A functional language without functors? Really? If one were disposed to not like Microsoft, as I admittedly am, one could conclude that they had gone ahead and crowbarred a perfectly good functional language, OCaml, into something they could get to run in their CLR so they could claim to “have” a functional language. Finally, because I don’t suspect, I know that Microsoft always prioritizes market dominance over product quality, I don’t plan to touch F#. But this is my personal preference, and clearly identified as such, while we’re really more concerned with making a good recommendation for mary.ja45 .
I have better reasons to recommend Lisp over F# and even OCaml and Haskell. These are mostly based on the historic preponderance of Lisp over any other language in the AI field.
The bulk of AI literature is based on programs written in Lisp or Prolog. If nothing else, good knowledge of Lisp would allow a student to understand the sample programs. My personal favorite AI megaproject, Cyc, has runtimes in your choice of Common Lisp or C.
In the TIOBE index of programming language (as seen and used in industry), Lisp takes 15th place while Haskell takes 43rd and F# and OCaml place below 50th. Presence on the market correlates with employment opportunities, naturally.
That said, it’s quite possible that a number of the younger “AI interesting” languages are poised to skyrocket. If some major research institute published some groundbreaking, defining-the-field research in, say, Scala, you’d see Scala’s popularity advance sharply in the research community and, with some lag, in industry.
I (obviously) can’t comment on F#’s other qualities but you’re as welcome to make recommendations as I was.
Pick the programming language with AI techniques the same way you pick a language for any other project:
solve?
the language?
I would recommend Prolog as a very good programming language used to implement AI systems.
I’ll throw Scala into the pot.
I’ve solved all exercises from a basic AI course in Scala. It worked really well.
Python seems to be used a lot in the general scientific community. It has a lot of libraries available and it’s easy to learn.
There is also a java framework called weka, developped by the university of waikato. I don’t know wether it anwsers your question, but it may help.
Quoting wikipedia: «Weka supports several standard data mining tasks, more specifically, data preprocessing, clustering, classification, regression, visualization» and more.
If by “all of AI” you also mean machine learning, which I guess, Matlab, R and Python+Scipy should definately be mentioned.
It matters probably whether the programming environment is academic or not, but for most non-academic AI application development I would recommend sticking with a mainstream language like Java or C++. One needs to be able to interface readily with other COTS or open-source software packages, and this can sometimes be difficult or impossible in more “exotic” languages. For academic work this may be a less critical issue.
Additionally, performance can be important for many applications, and mainstream languages generally have the most heavily-optimized compilers, e.g., C++ or Java.
It is true that functional programming languages like LISP, Scheme, etc have specialized features that may make it easier to implement particular AI methods, but I do not believe this to be true for AI-related programming as a whole, e.g., quantitative machine learning methods usually don’t require a functional language. If you need access to both functional constructs and general software packages, there are some tools for LISP to help with this, and the recently-developed Clojure is a LISP-variant that runs on the JVM and can access Java libraries. Also, Groovy is another JVM-based language that includes support for closures.
Lastly, some programmers like paradigm flexibility and/or fast prototyping for AI projects. Ruby and Python both see some AI-related usage for this reason as multi-paradigm languages that can also be used for scripting.
Like most things in programming, the best answer for which language to use in AI development will ultimately depend on the needs of your projects.
How about a framework written in Java, supporting “High Level Logic” and agent style communication.

It also depends on the size of your dataset. For web-scale datasets you may want to use Map-Reduce and that implies Hadoop. Hadoop is in Java — but you could use any language (Python, etc.) for your Map-Reduce functions.
I personally use Clojure for AI programming, and have found it to be a great all-rounder AI language.
