Training neural network for good taste in art I'm a newbie in machine learning, so excuse me in advance). I have an idea to make NN that can estimate visual pleasantness of arbitrary image. Like you have a bunch of images that you like, you train NN on them, then you show some random picture to NN and it estimates whether you'll like it or not. I wonder if there is any pervious effort made in this direction.
This question reminds me of a project I saw that used Deep Learning to rate selfies on twitter. But a quick google search shows that there are plenty of projects that are much closer to what you are interested in:

Rating Image Aesthetics using Deep Learning

Predicting Image Aesthetics with Deep Learning

Deep Understanding of Image Aesthetics (with data and model linked)

Understanding Aesthetics with Deep Learning

and probably dozens more. 

Of course if you are interested in predicting subjective pleasantness the above is only a beginning. In that case you may also take a look at recommender systems.
