This is a very powerful asymmetry: Anyone can notice a change in search results, but it’s extremely difficult to prove what caused it. That gives algorithm designers immense deniability.

The most widely used training algorithm of neural networks (NNs) is back propagation (BP), a gradient-based technique that requires significant computational effort. Metaheuristic search techniques ...

A search algorithm is a massive collection of other algorithms, each with its own purpose and task. Here's how it all works.

Why are algorithms used by dominant search engines becoming a privacy threat? Do algorithms ‘filter’ the internet according to user patterns?

Google's legendary search algorithm is carefully examined by Wired writer Steven Levy, who reveals that it will be updated about 550 times this year -- or once every 16 hours all year round.
