Unsupervised Word Embeddings Capture Latent Knowledge from Materials Science Literature,"
https://go.nature.com/32dCEfi

An algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge.

3.3 million abstracts of published materials science papers were fed into an algorithm called Word2vec.

By analyzing relationships between words the algorithm was able to predict discoveries of new thermoelectric materials years in advance and suggest as-yet unknown materials as candidates for thermoelectric materials.

Deep networks work by learning complex, often hierarchical internal representations of input data. These form a kind of functional language the network uses to describe the data.

Language can emerge from tasks like object recognition: has pointy ears, whiskers, tail => cat.

This relates to Wittgenstein’s "language-game" in Philosophical Investigations, where a functional language emerge from simple tasks before defining a vocabulary.

The visual vocabulary of a convolutional neural network seems to emerge from low level features such as edges and orientations, and builds up textures, patterns and composites, … and builds up even further into complete objects: houses, dogs, etc.
