question:
The digitization of data has resulted in making datasets available to millions of users in the form of relational databases and spreadsheet tables. However, a majority of these users come from diverse backgrounds and lack the programming expertise to query and analyze such tables. We present a system that allows for querying data tables using natural language questions, where the system translates the question into an executable SQL query. We use a deep sequence to sequence model in wich the decoder uses a simple type system of SQL expressions to structure the output prediction. Based on the type, the decoder either copies an output token from the input question using an attention-based copying mechanism or generates it from a fixed vocabulary. We also introduce a value-based loss function that transforms a distribution over locations to copy from into a distribution over the set of input tokens to improve training of our model. We evaluate our model on the recently released WikiSQL dataset and show that our model trained using only supervised learning significantly outperforms the current state-of-the-art Seq2SQL model that uses reinforcement learning.
answer:
We present a type-based pointer network model together with a value-based loss method to effectively train a neural model to translate natural language to SQL.


question:
Neural networks with low-precision weights and activations offer compelling
 efficiency advantages over their full-precision equivalents. The two most
 frequently discussed benefits of quantization are reduced memory consumption,
 and a faster forward pass when implemented with efficient bitwise
 operations. We propose a third benefit of very low-precision neural networks:
 improved robustness against some adversarial attacks, and in the worst case,
 performance that is on par with full-precision models. We focus on the very
 low-precision case where weights and activations are both quantized to $\pm$1,
 and note that stochastically quantizing weights in just one layer can sharply
 reduce the impact of iterative attacks. We observe that non-scaled binary neural
 networks exhibit a similar effect to the original \emph{defensive distillation}
 procedure that led to \emph{gradient masking}, and a false notion of security.
 We address this by conducting both black-box and white-box experiments with
 binary models that do not artificially mask gradients.
answer:
We conduct adversarial attacks against binarized neural networks and show that we reduce the impact of the strongest attacks, while maintaining comparable accuracy in a black-box setting


question:
While deep neural networks are a highly successful model class, their large memory footprint puts considerable strain on energy consumption, communication bandwidth, and storage requirements. Consequently, model size reduction has become an utmost goal in deep learning. A typical approach is to train a set of deterministic weights, while applying certain techniques such as pruning and quantization, in order that the empirical weight distribution becomes amenable to Shannon-style coding schemes. However, as shown in this paper, relaxing weight determinism and using a full variational distribution over weights allows for more efficient coding schemes and consequently higher compression rates. In particular, following the classical bits-back argument, we encode the network weights using a random sample, requiring only a number of bits corresponding to the Kullback-Leibler divergence between the sampled variational distribution and the encoding distribution. By imposing a constraint on the Kullback-Leibler divergence, we are able to explicitly control the compression rate, while optimizing the expected loss on the training set. The employed encoding scheme can be shown to be close to the optimal information-theoretical lower bound, with respect to the employed variational family. Our method sets new state-of-the-art in neural network compression, as it strictly dominates previous approaches in a Pareto sense: On the benchmarks LeNet-5/MNIST and VGG-16/CIFAR-10, our approach yields the best test performance for a fixed memory budget, and vice versa, it achieves the highest compression rates for a fixed test performance.
answer:

This paper proposes an effective method to compress neural networks based on recent results in information theory.
