Criticality and Safety Margins for Reinforcement Learning
Alexander Grushin, Walt Woods, Alvaro Velasquez +1
State of the art reinforcement learning methods sometimes encounter unsafe situations. Identifying when these situations occur is of interest both for post-hoc analysis and during…
Combining AI Control Systems and Human Decision Support via Robustness and Criticality
Walt Woods, Alexander Grushin, Simon Khan +1
AI-enabled capabilities are reaching the requisite level of maturity to be deployed in the real world, yet do not always make correct or safe decisions. One way of addressing these…
Safety Margins for Reinforcement Learning
Alexander Grushin, Walt Woods, Alvaro Velasquez +1
Any autonomous controller will be unsafe in some situations. The ability to quantitatively identify when these unsafe situations are about to occur is crucial for drawing timely hu…
LAGOON: An Analysis Tool for Open Source Communities
Sourya Dey, Walt Woods
This paper presents LAGOON -- an open source platform for understanding the complex ecosystems of Open Source Software (OSS) communities. The platform currently utilizes spatiotemp…
Anomaly Detection with Neural Parsers That Never Reject
Alexander Grushin, Walt Woods
Reinforcement learning has recently shown promise as a technique for training an artificial neural network to parse sentences in some unknown format, through a body of work known a…
RL-GRIT: Reinforcement Learning for Grammar Inference
Walt Woods
When working to understand usage of a data format, examples of the data format are often more representative than the format's specification. For example, two different application…
Spoken Digit Classification by In-Materio Reservoir Computing with Neuromorphic Atomic Switch Networks
Sam Lilak, Walt Woods, Kelsey Scharnhorst +4
Atomic Switch Networks (ASN) comprising silver iodide (AgI) junctions, a material previously unexplored as functional memristive elements within highly-interconnected nanowire netw…
Adversarial Explanations for Understanding Image Classification Decisions and Improved Neural Network Robustness
Walt Woods, Jack Chen, Christof Teuscher
For sensitive problems, such as medical imaging or fraud detection, Neural Network (NN) adoption has been slow due to concerns about their reliability, leading to a number of algor…
Fast and Accurate Sparse Coding of Visual Stimuli with a Simple, Ultra-Low-Energy Spiking Architecture
Walt Woods, Christof Teuscher
Memristive crossbars have become a popular means for realizing unsupervised and supervised learning techniques. In previous neuromorphic architectures with leaky integrate-and-fire…
