Facebook Can Now Deliver Ads That Are Dynamically Tailored to Each User - Search Engine Journal


Facebook is rolling out new advertising features that use machine learning to dynamically customize ads for individual users. This gives advertisers the ability to serve personalized ads when they may otherwise lack the time and resources required to deliver personally relevant ad experiences.

Building a Deep Image Search Engine using tf.Keras


Imagine having a data collection of hundreds of thousands to millions of images without any metadata describing the content of each image. How can we build a system that is able to find a sub-set of those images that best answer a user's search query? What we will basically need is a search engine that is able to rank image results given how well they correspond to the search query, which can be either expressed in a natural language or by another query image.

I could not find a data-set of search result ranking that is big enough but I was able to get this data-set:

An inorganic site structure is a linking pattern that uses internal site-level link signals (with subdomains) or cross-site linking patterns (with external domains) in order to manipulate search engine rankings. While these spam techniques already existed, Bing introduced the concept of calling them "inorganic site structure" in order to describe them.

Pinterest Launches a Refresh of Its Mobile App - Search Engine Journal


Pinterest has updated the look of its app for iOS and Android with a renewed focus on personalized recommendations and a more efficient use of space.
