Recently, Yelp made available a sample dataset from the greater Phoenix metropolitan area including around 11.000 business, 8000 checkin-sets, 43.000 users and 230.000 user reviews. With the help of this data, data scientists can execute real-life experiments with various data mining/machine learning algorithms. In our case, we are interested in finding out whether it is possible
A few months ago, I discovered Vertica’s “Counting Triangles”-article through Prismatic. The blog post describes a number of benchmarks on counting triangles in large networks. A triangle is detected whenever a vertex has two adjacent vertices that are also adjacent to each other. Imagine your social network; if two of your friends are also friends
Today, Datablend announces Similr to be available for beta sign-up. Similr allows scientist (both from academics and enterprise) to quickly search for compounds that exhibit a particular chemical structure. It employs a wide range of fingerprinting algorithms, which combined, allow to identify matching compounds in millisecond time. Similr’s functionalities are available through a flexible and
Recently, I’ve started implementing a number of Redis-based solutions for a Datablend customer. Redis is frequently referred to as the Swiss Army Knife of NoSQL databases and rightfully deserves that title. At its core, it is an in-memory key-value datastore.

For this challenge, Hubway released a CSV-file, containing over half a million rides. Each entry
