Beyond Accuracy
Re-work Toronto 2018 Deep neural networks have made a spectacular leap from research to the applied domain. The use of convolutional neural networks has allowed for large gains in test-set accuracy on image classification tasks. However, there is consensus that test-set accuracy is an inadequate measure of other properties we may care about like adversarial robustness, fairness, model compression or interpretability of a model. In this talk, we will consider some of the challenges associated with measuring progress on training model functions that fulfill multiple desirable characteristics. Slides here, video here. |

ROAR: RemOve And Retrain
ICML 2018 Estimating the influence of a given feature to a model prediction is challenging. We introduce ROAR, RemOve And Retrain, a benchmark to evaluate the accuracy of interpretability methods that estimate input feature importance in deep neural networks. This evaluation produces thought-provoking results -- we find that several estimators are less accurate than a random assignment of feature importance. Slides here. |

Explaining deep Neural Network Model Predictions
PyBay, San Francisco How can we explain how deep neural networks arrive at decisions? Feature representation is complex and to the human eye opaque; instead a set of interpretability tools intuit what the model has learned by looking at what inputs it pays attention to. This talk will introduce some of the challenges associated with identifying these salient inputs and discuss desirable properties methods should fulfill in order to build trust between humans and algorithm. Slides here, video here. |

Talk at the Data Institute — October 22nd, 2017
How can we explain how deep neural networks arrive at decisions? Feature representation is complex and to the human eye opaque; instead a set of methods called saliency maps intuit what the model has learned by looking at what inputs it pays attention to. This talk will introduce some of the challenges associated with identifying these salient inputs and discuss desirable properties methods should fulfill in order to build trust between end user and algorithm
