Tensor Product Generation Networks for Deep NLP Modeling
We present a new approach to the design of deep networks for natural language
processing (NLP), based on the general technique of Tensor Product
Representations (TPRs) for encoding and processing symbol structures in
distributed neural networks. A network architecture --- the Tensor Product
Generation Network (TPGN) --- is proposed which is capable in principle of
carrying out TPR computation, but which uses unconstrained deep learning to
design its internal representations. Instantiated in a model for image-caption
generation, TPGN outperforms LSTM baselines when evaluated on the COCO dataset.
The TPR-capable structure enables interpretation of internal representations
and operations, which prove to contain considerable grammatical content. Our
caption-generation model can be interpreted as generating sequences of
grammatical categories and retrieving words by their categories from a plan
encoded as a distributed representation
e-SNLI: Natural Language Inference with Natural Language Explanations
In order for machine learning to garner widespread public adoption, models
must be able to provide interpretable and robust explanations for their
decisions, as well as learn from human-provided explanations at train time. In
this work, we extend the Stanford Natural Language Inference dataset with an
additional layer of human-annotated natural language explanations of the
entailment relations. We further implement models that incorporate these
explanations into their training process and output them at test time. We show
how our corpus of explanations, which we call e-SNLI, can be used for various
goals, such as obtaining full sentence justifications of a model's decisions,
improving universal sentence representations and transferring to out-of-domain
NLI datasets. Our dataset thus opens up a range of research directions for
using natural language explanations, both for improving models and for
asserting their trust.Comment: NeurIPS 201
