Support Vector Machines (SVM) in Ruby. By Ilya Grigorik on January 07, 2008 Your Family Guy fan-site is riding a wave of viral referrals, the community has grown tenfold in last month alone!
First, you've deployed an SVD recommendation system, then you've optimized the site content and layout with the help of decision trees, but of course, that wasn't enough, and you've also added a Bayes classifier to help you filter and rank the content - no wonder the site is doing so well! The community is buzzing with action, but as with any honey pot with high traffic, the spam bots have also arrived on the scene. No problem, you think to yourself, SVMs will be perfect for this one. History of Support Vector Machines Support Vector Machine (SVM) is a supervised learning algorithm developed by Vladimir Vapnik and his co-workers at AT&T Bell Labs in the mid 90's.
Installing and Configuring LIBSVM with Ruby There is a plethora of available SVM implementations, but we will choose LIBSVM for our purposes. Training the Support Vector Machine. 7 Essential Resources & Tips To Get Started With Data Science. 1.
Data Science Data science is an umbrella term for a collection of techniques from many distinct areas such as computer science, statistics, machine learning to name just a few. The main objective is to extract information from data and turn it into knowledge which you can base your further decisions on. It sounds easy, but it’s not necessarily always straightforward. Usually the process comprises many steps starting with a research question. The Python for Data Analysis book is a great starting point, it guides you through all these stages and helps you to get this workflow under your skin. A definition of ´Data Scientist´ by Josh Wills 2. First of all you need an interesting data set to play with.
Data is wherever you look, however, it’s not always trivial to get what you want. 3. Having a good understanding of statistics is extremely helpful when performing data analysis. 4. In layman’s terms, the goal of machine learning algorithms is to learn to make decisions based on data. 5. 7. Functors, Applicatives, And Monads In Pictures - adit.io. Here’s a simple value: And we know how to apply a function to this value: Simple enough.
Lets extend this by saying that any value can be in a context. For now you can think of a context as a box that you can put a value in: Now when you apply a function to this value, you’ll get different results depending on the context. Scheme DSL: SchemeUnit and SchemeQL. Programming in Schelog. Schelog is an embedding of Prolog-style logic programming in Scheme.
“Embedding” means you don’t lose Scheme: You can use Prolog-style and conventional Scheme code fragments alongside each other. Schelog contains the full repertoire of Prolog features, including meta-logical and second-order (“set”) predicates, leaving out only those features that could more easily and more efficiently be done with Scheme subexpressions. The Schelog implementation uses the approach to logic programming described in Felleisen  and Haynes . In contrast to earlier Lisp simulations of Prolog , which used explicit continuation arguments to store failure (backtrack) information, the Felleisen and Haynes model uses the implicit reified continuations of Scheme as provided by the operator call‑with‑current‑continuation (aka call/cc).
This allows Schelog to be an embedding, ie, logic programming is not built as a new language on top of Scheme, but is used alongside Scheme’s other features. 4 Backtracking. Automata via Macros (Lisp) Pattern Matching for Scheme. Deep Learning in a Nutshell: Core Concepts. This post is the first in a series I’ll be writing for Parallel Forall that aims to provide an intuitive and gentle introduction to deep learning.
It covers the most important deep learning concepts and aims to provide an understanding of each concept rather than its mathematical and theoretical details. While the mathematical terminology is sometimes necessary and can further understanding, these posts use analogies and images whenever possible to provide easily digestible bits comprising an intuitive overview of the field of deep learning. I wrote this series in a glossary style so it can also be used as a reference for deep learning concepts. Part 1 focuses on introducing the main concepts of deep learning. Future posts will provide historical background and delve into the training procedures, algorithms and practical tricks that are used in training for deep learning. Core Concepts.
