Assessing Cardiovascular Risk Factors with Computer Vision

research.googleblog.com

Using deep learning algorithms trained on data from 284,335 patients, the team was able to predict cardiovascular risk factors from retinal images with surprisingly high accuracy for patients from two independent datasets of 12,026 and 999 patients. The algorithm could distinguish the retinal images of a smoker from that of a non-smoker 71% of the time.

[1802.07740] Machine Theory of Mind

arxiv.org

ToMnet uses meta-learning to build models of the agents it encounters, from observations of their behavior alone. Through this process, it acquires a strong prior model for agents’ behavior, as well as the ability to bootstrap to richer predictions about agents’ characteristics and mental states using only a small number of behavioral observations. The authors apply the ToMnet to agents behaving in simple gridworld environments, showing that it learns to model random, algorithmic, and deep reinforcement learning agents from varied populations.

Diversity is All You Need

sites.google.com

A method for learning useful skills without a reward function by maximizing an information theoretic objective using a maximum entropy policy. On a variety of simulated robotic tasks, the authors show that this simple exploration objective results in the unsupervised emergence of diverse skills, such as walking and jumping

[1802.08294] Unicorn: Continual Learning with a Universal, Off-policy Agent

arxiv.org

Some real-world domains are best characterized as a single task, but for others this perspective is limiting. Instead, some tasks continually grow in complexity, in tandem with the agent’s competence. In continual learning, also referred to as lifelong learning, there are no explicit task boundaries or curricula. The authors propose a novel agent architecture called Unicorn, which demonstrates strong continual learning and outperforms several baseline agents on the proposed 3D domain. The agent achieves this by jointly representing and learning multiple policies efficiently, using a parallel off-policy learning setup.

[1802.07569] Continual Lifelong Learning with Neural Networks: A Review

arxiv.org

The ability to learn from continuous streams of information is crucial for computational learning systems and autonomous agents (inter)acting in the real world. In this review, the authors critically summarize the main challenges linked to continual lifelong learning for artificial learning systems and compare existing neural network approaches that alleviate, to different extents, catastrophic interference.

[1802.08395] Towards end-to-end spoken language understanding

arxiv.org

In his paper, the authors present our study on an end-to-end learning system for spoken language understanding. With this unified approach, one can infer the semantic meaning directly from audio features without the intermediate text representation. This study showed that the trained model can achieve reasonably good results and demonstrated that the model can capture the semantic attention directly from the audio features.
