Datumbox Machine Learning Framework

In most Supervised Machine Learning problems we need to define a model and estimate its parameters based on a training dataset. A popular and easy-to-use technique to calculate those parameters is to minimize model’s error with Gradient Descent. The ... [More] Gradient Descent estimates the weights of the model in many iterations by minimizing a cost function […] [Less]

Understanding how the human brain works is a topic of active research and several scientists from various fields publish numerous of papers every year. Why is it important? Because knowing how our brain works will enable us to understand how we operate/think and perhaps enable us build truly intelligent machines in the future. The first […]

In this tutorial we will discuss about Naive Bayes text classifier. Naive Bayes is one of the simplest classifiers that one can use because of the simple mathematics that are involved and due to the fact that it is easy to code with every standard programming language including PHP, C#, JAVA etc. Update: The Datumbox […]

The Datumbox API can be used by any modern computer language which enables you to generate web requests. Our Machine Learning API can easily be implemented within minutes because it uses REST and JSON technologies and because all the requests are authenticated simply by passing your API Key. To test the API all you need […]

Sentiment Analysis (detecting document’s polarity, subjectivity and emotional states) is a difficult problem and several times I bumped into unexpected and interesting results. One of the strangest things that I found is that despite the fact that ...
