Amortized inference has led to efficient approximate inference for large datasets. The quality of posterior inference is largely determined by two factors: a) the ability of the variational distribution to model the true posterior and b) the capacity of the recognition network to generalize inference over all datapoint...

Information bottleneck (IB) is a method for extracting information from one random variable X that is relevant for predicting another random variable Y . To do so, IB identifies an intermediate "bottleneck" variable T that has low mutual information I(X; T ) and high mutual information I(Y ; T ). The IB curve character...

Adaptive gradient methods such as Adam have gained increasing popularity in deep learning optimization. However, it has been observed that compared with (stochastic) gradient descent, Adam can converge to a different solution with a significantly worse test error in many deep learning applications such as image classif...
Understanding the Generalization of Adam in Learning Neural Networks with Proper Regularization

While the Transformer architecture has become the de-facto standard for natural language processing tasks, its applications to computer vision remain limited. In vision, attention is either applied in conjunction with convolutional networks, or used to replace certain components of convolutional networks while keeping ...
AN IMAGE IS WORTH 16X16 WORDS: TRANSFORMERS FOR IMAGE RECOGNITION AT SCALE

Deep neural networks may easily memorize noisy labels present in real-world data, which degrades their ability to generalize. It is therefore important to track and evaluate the robustness of models against noisy label memorization. We propose a metric, called susceptibility, to gauge such memorization for neural netwo...

For text clustering, there is often a dilemma: one can either first embed each examples independently and then compute pair-wise similarities based on the embeddings, or use a crossattention model that takes a pair of examples as input and produces a similarity. The former is more scalable but the similarities often ha...
KwikBucks: Correlation Clustering with Cheap-Weak and Expensive-Strong Signals

This work establishes rigorous, novel and widely applicable stability guarantees and transferability bounds for graph convolutional networks -without reference to any underlying limit object or statistical distribution. Crucially, utilized graphshift operators (GSOs) are not necessarily assumed to be normal, allowing f...

Analogical reasoning is fundamental to human cognition and holds an important place in various fields. However, previous studies mainly focus on single-modal analogical reasoning and ignore taking advantage of structure knowledge. Notably, the research in cognitive psychology has demonstrated that information from mult...

The ability of overparameterized deep networks to generalize well has been linked to the fact that stochastic gradient descent (SGD) finds solutions that lie in flat, wide minima in the training loss -minima where the output of the network is resilient to small random noise added to its parameters. So far this observat...
