Sequential data is ubiquitous and modeling sequential data has been one of the most long-standing computer science problems. The goal of sequence modeling is to represent a sequence with a low-dimensional dense vector that incorporates as much information as possible. A fundamental type of information contained in sequences is the sequential dependency and a large body of research has been devoted to designing effective ways to capture it. Recently, sequence learning models such as recurrent...
Show moreSequential data is ubiquitous and modeling sequential data has been one of the most long-standing computer science problems. The goal of sequence modeling is to represent a sequence with a low-dimensional dense vector that incorporates as much information as possible. A fundamental type of information contained in sequences is the sequential dependency and a large body of research has been devoted to designing effective ways to capture it. Recently, sequence learning models such as recurrent neural networks (RNNs), temporal convolutional networks, and Transformer have gained tremendous popularity in modeling sequential data. Equipped with effective structures such as gating mechanisms, large receptive fields, and attention mechanisms, these models have achieved great success in many applications of a wide range of fields.However, besides the sequential dependency, sequences also exhibit side information that remains under-explored. Thus, in the thesis, we study the problem of sequence learning with side information. Specifically, we present our efforts devoted to building sequence learning models to effectively and efficiently capture side information that is commonly seen in sequential data. In addition, we show that side information can play an important role in sequence learning tasks as it can provide rich information that is complementary to the sequential dependency. More importantly, we apply our proposed models in various real-world applications and have achieved promising results.
