We propose a local coherence model based on a convolutional neural network that operates over the entity grid representation of a text. The model captures long range entity transitions along with entity-specific features without loosing generalization, thanks to the power of distributed representation. We present a pairwise ranking method to train the model in an end-to-end fashion on a task and learn task-specific high level features. Our evaluation on three different coherence assessment tasks demonstrates that our model achieves state of the art results outperforming existing models by a good margin.
Solution: A Neural Local Coherence Model
Why? This statement "A Neural Local Coherence Model" is taken from the subtext "convolutional neural network" and its explanation in the passage. This is a positive example because the title belongs to the mentions in the passage

New input: Although a number of auto-encoder models enforce sparsity explicitly in their learned representation while others don't, there has been little formal analysis on what encourages sparsity in these models in general. Therefore, our objective here is to formally study this general problem for regularized auto-encoders. We show that both regularization and activation function play an important role in encouraging sparsity. We provide sufficient conditions on both these criteria and show that multiple popular models like De-noising and Contractive auto-encoder and activations like Rectified Linear and Sigmoid satisfy these conditions; thus explaining sparsity in their learned representation. Our theoretical and empirical analysis together, throws light on the properties of regularization/activation that are conducive to sparsity. As a by-product of the insights gained from our analysis, we also propose a new activation function that overcomes the individual drawbacks of multiple existing activations (in terms of sparsity) and hence produces performance at par (or better) with the best performing activation for all auto-encoder models discussed.
Solution:
Why Regularized Auto-Encoders learn Sparse Representation?
