Graph Neural Network Based Coarse-Grained Mapping Prediction

The selection of coarse-grained (CG) mapping operators is a critical step for CG molecular dynamics (MD) simulation. It is still an open question about what is optimal for this choice and there is a need for theory. The current state-of-the art method is mapping operators manually selected by experts. In this work, we demonstrate an automated approach by viewing this problem as supervised learning where we seek to reproduce the mapping operators produced by experts. We present a graph neural network based CG mapping predictor called DEEP SUPERVISED GRAPH PARTITIONING MODEL(DSGPM) that treats mapping operators as a graph segmentation problem. DSGPM is trained on a novel dataset, Human-annotated Mappings (HAM), consisting of 1,206 molecules with expert annotated mapping operators. HAM can be used to facilitate further research in this area. Our model uses a novel metric learning objective to produce high-quality atomic features that are used in spectral clustering. The results show that the DSGPM outperforms state-of-the-art methods in the field of graph segmentation. Finally, we find that predicted CG mapping operators indeed result in good CG MD models when used in simulation.
Deep CV: Advanced Convolutional Layers
In the world of Deep Computer Vision, there are several types of convolutional layers that differ from the original convolutional layer which was discussed in the previous Deep CV tutorial. These layers are used in many popular advanced convolutional neural network implementations found in the Deep Learning research side of Computer Vision. Each of these layers has a different mechanism than the original convolutional layer and this allows each type of layer to have a particularly special function. Before getting into these advanced convolutional layers, let's first have a quick recap on how the original convolutional layer works. In the original convolutional layer, we have an input that has a shape (W*H*C) where W and H are the width and height of each feature map and C is the number of channels, which is basically the total number of feature maps.
DeepMind's Newest AI Programs Itself to Make All the Right Decisions
Three main deep learning approaches are supervised, unsupervised, and reinforcement learning. The first two consume huge amounts of data (like images or articles), look for patterns in the data, and use those patterns to inform actions (like identifying an image of a cat). To us, this is a pretty alien way to learn about the world. Not only would it be mind-numbingly dull to review millions of cat images, it'd take us years or more to do what these programs do in hours or days. And of course, we can learn what a cat looks like from just a few examples.

The data and targets are then split into training, and testing data be keeping 10% of data as testing and 90% as training data. A checkpoint is created, which will save the model, which will have the minimum validation loss. Then the training data is then fitted in the model so that predictions can be made in the future.

Amazon scientists applying deep neural networks to custom skills
At the Alexa Live event today, Nedim Fresko, vice president of Alexa Devices and Developers, said Amazon is now using deep neural networks to improve customers' experience with Alexa skills. Deep neural networks (DNNs) consist of thousands or even millions of densely connected processing nodes, loosely modeled on the neurons of the brain. DNNs learn to perform tasks by looking for patterns in huge sets of training data. "We are adopting deep neural networks to improve Alexa's natural-language understanding of individual words and sentences," Fresko told the Alexa Live audience. "We've begun applying the technology to custom skills and are excited by the early results."
Quantum AI is still years from enterprise prime time
Quantum computing's potential to revolutionize AI depends on growth of a developer ecosystem in which suitable tools, skills, and platforms are in abundance. These milestones are all still at least a few years in the future. What follows is an analysis of the quantum AI industry's maturity at the present time. Quantum AI executes ML (machine learning), DL (deep learning), and other data-driven AI algorithms reasonably well. As an approach, quantum AI has moved well beyond the proof-of-concept stage.
The Battle Between Google & Facebook That Nobody Is Talking About
When we talk about competition between tech giants, here are the usual suspects – Google competes with Facebook for ad revenues, Google competes with AWS & Microsoft for cloud revenue, and the list goes on. But an area that's often missed from the technical parlance especially for those who are close to the ML developments, is how Facebook and Google are competing for a pie of ML developers attention through open source frameworks. Google launched Tensorflow with much fanfare in November 2015. Facebook launched Pytorch in 2016. Both are open source frameworks/ libraries for machine learning, used primarily on Python but can also be used by developers on C & Julia.
