Guided Learning of Nonconvex Models through Successive Functional Gradient Optimization

no code implementations ICML 2020 Rie Johnson, Tong Zhang

This paper presents a framework of successive functional gradient optimization for training nonconvex models such as neural networks, where training is driven by mirror descent in a function space.

Composite Functional Gradient Learning of Generative Adversarial Models

no code implementations ICML 2018 Rie Johnson, Tong Zhang

This paper first presents a theory for generative adversarial methods that does not rely on the traditional minimax formulation.

Convolutional Neural Networks for Text Categorization: Shallow Word-level vs. Deep Character-level

no code implementations31 Aug 2016 Rie Johnson, Tong Zhang

This paper reports the performances of shallow word-level convolutional neural networks (CNN), our earlier work (2015), on the eight datasets with relatively large training data that were used for testing the very deep character-level CNN in Conneau et al. (2016).

Text Categorization

Supervised and Semi-Supervised Text Categorization using LSTM for Region Embeddings

no code implementations7 Feb 2016 Rie Johnson, Tong Zhang

The best results were obtained by combining region embeddings in the form of LSTM and convolution layers trained on unlabeled data.

Effective Use of Word Order for Text Categorization with Convolutional Neural Networks

4 code implementations HLT 2015 Rie Johnson, Tong Zhang

Convolutional neural network (CNN) is a neural network that can make use of the internal structure of data such as the 2D structure of image data.

Accelerating Stochastic Gradient Descent using Predictive Variance Reduction

no code implementations NeurIPS 2013 Rie Johnson, Tong Zhang

Stochastic gradient descent is popular for large scale optimization but has slow convergence asymptotically due to the inherent variance.

Structured Prediction

Learning Nonlinear Functions Using Regularized Greedy Forest

1 code implementation5 Sep 2011 Rie Johnson, Tong Zhang

We consider the problem of learning a forest of nonlinear decision rules with general loss functions.
