Sequence Classification is a specific type of task where the input data consists of sequences, such as sequences of words in a sentence, DNA sequences, or time-series data. The goal is to predict the class or label for the entire sequence. Recurrent neural networks (RNNs) and long short-term memory networks (LSTMs) are often used for sequence classification tasks due to their ability to capture temporal dependencies in the data.


Learning Context-Sensitive Convolutional Filters for Text Processing

Learning Context-Sensitive Convolutional Filters for Text Processing Convolutional neural networks (CNNs) have recently emerged as a popular building block for natural language processing (NLP). Despite their success, most existing CNN models employed in NLP share the same learned (and static) set of filters for all input sentences. In this paper, we consider an approach of using a small meta network to learn context-sensitive convolutional filters for text processing. The role of meta network is to abstract the contextual information of a sentence or document into a set of input-sensitive filters. We further generalize this framework to model sentence pairs, where a bidirectional filter generation mechanism is introduced to encapsulate co-dependent sentence representations. In our benchmarks on four different tasks, including ontology classification, sentiment analysis, answer sentence selection, and paraphrase identification, our proposed model, a modified CNN with context-sensitive filters, consistently outperforms the standard CNN and attention-based CNN baselines. By visualizing the learned context-sensitive filters, we further validate and rationalize the effectiveness of proposed framework.
