Rijndael / AES (128 bit) in VB.net, PHP, Python

By Adam On November 21, 2012 · 2 Comments

Being able to transport encrypted data is important in some of my projects at work. One-way hashes using MD5 usually suffice for most encryption purposes but Symmetric Encryption algorithms are important for encrypting and then decrypting data. For this, we use the Rijndael and AES algorithm in a few different languages.

Cosine Similarity in MS SQL

By Adam On June 20, 2012 · 8 Comments

Cosine similarity measures the angle between two vectors and can be used to perform similarity between text strings. In the following code, the two input strings are vectorized and the similarity is returned as a floating point value between 0 and 1.

Multidimensional Scaling

By Adam On April 29, 2012 · Leave a Comment

Multidimensional Scaling (MDS) is a linear embedding method used when we only know the pairwise distances between data points. For linear systems, MDS works well with as little as 10 points and the system is 2 dimensional.

An Overview of Particle Swarm Optimization

By Adam On January 18, 2012 · 2 Comments

Particle swarm optimization is often used to optimize functions in rather unfriendly non-convex, non-continuous spaces. The idea behind the algorithm involves a swarm of particles flying through a space both collaboratively and independently.
