If you are practicing machine learning, you are likely going to run into this at some point. Basically the reason we use feature scaling is to help our algorithms train faster and better. Lets begin by taking a standard theta optimization equation to help better understand the problem.
So I wrote an article earlier “Linear Regression From Scratch”. Many folks have pointed out that this is in fact not the optimal approach. Now being the perfectionist I decided to re-implement. Not to mention it works great in my own libraries. The following article discussing converting the original code into code that uses linear algebra. Beyond this, it still works in PCL for xamarin, Hoo-Rah Xamarin!
Here in South Florida we have a strong Machine Learning and Data Science community and therefor it is easy to get a study group together. This article is a recap from the first meeting of our study group. Note that this first meeting is the week before the class started. Therefor this article is a great introduction to machine learning, languages, commitments and more generally applicable questions and concerns.
So today we will do a quick conversion from mathematical notations of Algebra into a real algorithm that can be executed. Note we will not be covering gradient descent, but rather only cost functions, errors and execution of these to provide the framework for gradient descent. Gradient descent has so many flavors that it deserves its own article.
This article is a video tutorial on introduction to the very bare basics of R. Its a bit dry, but it is the underlying components of everything covered in the interesting stuff. Can’t do cool stuff without understanding the basics first.
Today is a freaking cool day. Why do you ask? Because today I am writing an article on how to use two of the coolest freaking big data/data science tools out there together to do epic shit! Lets start with HBase. HBase is a way to have a big data solution with query performance at an interactive level. So many folks are starting to just dump data into HBase. In the project teddy solution, we are dumping tweets, dialogue and dialogue annotations to power our open domain conversational api. There really is no other way that is easy to use for us to do this.
The second part of project teddy is to predict based on an incoming conversational component, what sort of response the speaker is attempting to illicit from the teddy bear. If we power our teddy bear with predictive analytics and big data, this would be perfect. What better platform to do this quickly and easily than AzureML?
