Community Center by Rohit_43 Does anyone know a good Java machine learning library I can use for a commercial product? Weka and Rapidminer unfortunately do not allow this. I already found Apache Mahout and Java Data Mininng Package. Has anyone experience with them and provide some decision support? The task calls for clustering and classification algorithms. Re: How are "real" data analytics applications programmed? Programming Computer Science by Hiroshe > Python's too slow to use for anything very big Stop right there. Yes, implementing the algorithms used in pure python is not a good idea, but thats not how the scientific community uses python. For scientific and numerical computation, python is really more of a 'glue' language and components are written in a more optimum way. I would … Re: How are "real" data analytics applications programmed? Programming Computer Science by L7Sqr It seems you are making some assumptions that you have not verified yourself. The ones **Hiroshe** point out are good examples: Python, if used correctly, fits very nicely into an analysts toolbox regardless of scale. Have you had a *specific* example where this is not the case? R has some issues on a 32-bit architecture due to it's internal … Re: How are "real" data analytics applications programmed?

Community Center by rproffitt I can't find the restriction you noted (commercial use) at https://waikato.github.io/weka-wiki/faq/ Maybe you meant you couldn't commit to open source for your product?
