Neural Compositional Denotational Semantics for Question Answering
Conference on Empirical Methods in Natural Language Processing (EMNLP)
Answering compositional questions requiring multi-step reasoning is challenging. We introduce an end-to-end differentiable model for interpreting questions about a knowledge graph (KG), which is inspired by formal approaches to semantics.

Semantic Parsing for Task Oriented Dialog using Hierarchical Representations
Conference on Empirical Methods in Natural Language Processing (EMNLP)
Task oriented dialog systems typically first parse user utterances to semantic frames comprised of intents and slots. Previous work on…

SING: Symbol-to-Instrument Neural Generator
Conference on Neural Information Processing Systems (NIPS)
In this work, we study the more computationally efficient alternative of generating the waveform frame-by-frame with large strides. We present SING, a lightweight neural audio synthesizer for the original task of generating musical notes given desired instrument, pitch and velocity.

Value-aware Quantization for Training and Inference of Neural Networks
European Conference on Computer Vision (ECCV)
We propose a novel value-aware quantization which applies aggressively reduced precision to the majority of data while separately handling a small amount of large values in high precision, which reduces total quantization errors under very low precision.

Predicting Future Instance Segmentation by Forecasting Convolutional Features
European Conference on Computer Vision (ECCV)
Anticipating future events is an important prerequisite towards intelligent behavior. Video forecasting has been studied as a proxy task towards this goal. Recent work has shown that to predict semantic segmentation of future frames, forecasting at the semantic level is more effective than forecasting RGB frames and then segmenting these. In this paper we consider the more challenging problem of future instance segmentation, which additionally segments out individual objects.

Multi-Fiber Networks for Video Recognition
European Conference on Computer Vision (ECCV)
In this paper, we aim to reduce the computational cost of spatio-temporal deep neural networks, making them run as fast as their 2D counterparts while preserving state-of-the-art accuracy on video recognition benchmarks.

Deep Clustering for Unsupervised Learning of Visual Features
European Conference on Computer Vision (ECCV)
In this work, we present DeepCluster, a clustering method that jointly learns the parameters of a neural network and the cluster assignments of the resulting features.

Memory Aware Synapses: Learning what (not) to forget
European Conference on Computer Vision (ECCV)
Humans can learn in a continuous manner. Old rarely utilized knowledge can be overwritten by new incoming information while important, frequently used knowledge is prevented from being erased. In artificial learning systems, lifelong learning so far has focused mainly on accumulating knowledge over tasks and overcoming catastrophic forgetting. In this paper, we argue that, given the limited model capacity and the unlimited new information to be learned, knowledge has to be preserved or erased selectively.

Choose Your Neuron: Incorporating Domain Knowledge through Neuron-Importance
European Conference on Computer Vision (ECCV)
Individual neurons in convolutional neural networks supervised for image-level classification tasks have been shown to implicitly learn semantically meaningful concepts ranging from simple textures and shapes to whole or partial objects – forming a “dictionary” of concepts acquired through the learning process. In this work we introduce a simple, efficient zero-shot learning approach based on this observation.

Graph R-CNN for Scene Graph Generation
European Conference on Computer Vision (ECCV)
We propose a novel scene graph generation model called Graph R-CNN, that is both effective and efficient at detecting objects and their relations in images.
