Parity Considerations for Mex-Related Partition Functions of Andrews and Newman [article]

Robson da Silva, James A. Sellers
2020 arXiv   pre-print
In a recent paper, Andrews and Newman extended the mex-function to integer partitions and proved many partition identities connected with these functions.  ...  Introduction In [1] , Andrews and Newman generalized the minimal excludant function (mexfunction) to apply to integer partitions.  ...  Indeed, Andrews and Newman proved the following connections between these two functions and the enumeration of partitions according to their rank and their crank.

Learning Parameterized Skills [article]

Bruno Da Silva, Andrew Barto
2012 arXiv   pre-print
We introduce a method for constructing skills capable of solving tasks drawn from a distribution of parameterized reinforcement learning problems. The method draws example tasks from a distribution of interest and uses the corresponding learned policies to estimate the topology of the lower-dimensional piecewise-smooth manifold on which the skill policies lie. This manifold models how policy parameters change as task parameters vary. The method identifies the number of charts that compose the
more » ... nifold and then applies non-linear regression in each chart to construct a parameterized skill by predicting policy parameters from task parameters. We evaluate our method on an underactuated simulated robotic arm tasked with learning to accurately throw darts at a parameterized target location.

Multimodal Punctuation Prediction with Contextual Dropout [article]

Andrew Silva, Barry-John Theobald, Nicholas Apostoloff
2021 arXiv   pre-print
Automatic speech recognition (ASR) is widely used in consumer electronics. ASR greatly improves the utility and accessibility of technology, but usually the output is only word sequences without punctuation. This can result in ambiguity in inferring user-intent. We first present a transformer-based approach for punctuation prediction that achieves 8% improvement on the IWSLT 2012 TED Task, beating the previous state of the art [1]. We next describe our multimodal model that learns from both
more » ... and audio, which achieves 8% improvement over the text-only algorithm on an internal dataset for which we have both the audio and transcriptions. Finally, we present an approach to learning a model using contextual dropout that allows us to handle variable amounts of future context at test time.

Effects of Interruptibility-Aware Robot Behavior [article]

Siddhartha Banerjee, Andrew Silva, Karen Feigh, Sonia Chernova
2018 arXiv   pre-print
As robots become increasingly prevalent in human environments, there will inevitably be times when a robot needs to interrupt a human to initiate an interaction. Our work introduces the first interruptibility-aware mobile robot system, and evaluates the effects of interruptibility-awareness on human task performance, robot task performance, and on human interpretation of the robot's social aptitude. Our results show that our robot is effective at predicting interruptibility at high accuracy,

Results of a large-scale user study show that while participants are able to maintain task performance even in the presence of interruptions, interruptibility-awareness improves the robot's task performance and improves participant social perception of the robot.

Safe Coordination of Human-Robot Firefighting Teams [article]

Esmaeil Seraj and Andrew Silva and Matthew Gombolay
2019 arXiv   pre-print
Wildfires are destructive and inflict massive, irreversible harm to victims' lives and natural resources. Researchers have proposed commissioning unmanned aerial vehicles (UAVs) to provide firefighters with real-time tracking information; yet, these UAVs are not able to reason about a fire's track, including current location, measurement, and uncertainty, as well as propagation. We propose a model-predictive, probabilistically safe distributed control algorithm for human-robot collaboration in
more » ... ildfire fighting. The proposed algorithm overcomes the limitations of prior work by explicitly estimating the latent fire propagation dynamics to enable intelligent, time-extended coordination of the UAVs in support of on-the-ground human firefighters. We derive a novel, analytical bound that enables UAVs to distribute their resources and provides a probabilistic guarantee of the humans' safety while preserving the UAVs' ability to cover an entire fire.

Action2Vec: A Crossmodal Embedding Approach to Action Learning [article]

Meera Hahn, Andrew Silva, James M. Rehg
2019 arXiv   pre-print
We describe a novel cross-modal embedding space for actions, named Action2Vec, which combines linguistic cues from class labels with spatio-temporal features derived from video clips. Our approach uses a hierarchical recurrent network to capture the temporal structure of video features. We train our embedding using a joint loss that combines classification accuracy with similarity to Word2Vec semantics. We evaluate Action2Vec by performing zero shot action recognition and obtain state of the
more » ... results on three standard datasets. In addition, we present two novel analogy tests which quantify the extent to which our joint embedding captures distributional semantics. This is the first joint embedding space to combine verbs and action videos, and the first to be thoroughly evaluated with respect to its distributional semantics.
