Deep learning is progressing rapidly. There is a new interesting research paper every other week. This is a list of essential deep learning research by categories.
Fundamentals

Convolution Neural Networks (CNN)
These are the recent advances for CNN, original was Lecun-5 in the 98 paper mentioned above .

Image Detection
Finding a bounding box around different objects is harder than simply classifying an image. This a class of image localization and detection problems.
- Faster RCNN (there is also Fast RCNN and RCNN, Faster is incremental improvement over all), one of the best – https://arxiv.org/abs/1506.01497
- YOLO, supposed to be the most efficient – https://arxiv.org/abs/1612.08242
Generative Adversarial Neural Networks
One of the hottest areas of research. This is a class of algorithms where 2 neural networks collaborate to generate e.g. realistic images. One network produces fake images (faker), and the other network learns to decipher fake from real (detective). Both networks compete with each other and try to be good at their jobs, till the faker is so good that it can generate realistic images. Fake it till you make it!

Semi Supervised Learning
Getting labeled data is expensive, while unlabeled data is abundant. Techniques to use little bit of training data and lots of unlabeled data.

Visual Question Answering / Reasoning
Research on being able to ask question on images. e.g. asking if there are there more blue balls than yellow about an image.
- Inferring and Executing Programs For Visual Reasoning – https://arxiv.org/abs/1705.03633
- Relation Networks From Deep Mind, generic NN component that can be used on visual and text QA systems – https://arxiv.org/abs/1706.01427.pdf
Neural Style
Being able to take a picture and a style image e.g. a painting, and redraw the picture in the painting style. See my blog on painting like Picaso.

Recurrent Neural Networks (RNN)

- GRU – https://arxiv.org/abs/1502.02367
AutoEncoders
This is area of unsupervised learning. An auto encoder is a neural network that tries to recreate the original image. e.g. give it any picture and it will try to recreate the same image. Why would anyone want to do that. The neural network tries to learn a condensed representation of images given that there are commonalities. Auto encoders can be used to pre train a neural network with unlabeled data.
