Aspect-Based Sentiment Analysis (ABSA) is a fine-grained sentiment analysis task and has become a significant task with real-world scenario value. The challenge of this task is how to generate an effective text representation and construct an end-to-end model that can simultaneously detect (target, aspect, sentiment) triples from a sentence. Besides, the existing models do not take the heavily unbalanced distribution of labels into account and also do not give enough consideration to long-distance dependence of targets and aspect-sentiment pairs.

While we have seen significant advances in automatic summarization for text, research on speech summarization is still limited. In this work, we address the challenge of automatically generating teasers for TED talks. In the first step, we create a corpus for automatic summarization of TED and TEDx talks consisting of the talks' recording, their transcripts and their descriptions. The corpus is used to build a speech summarization system for the task. We adapt and combine pre-trained models for automatic speech recognition (ASR) and text summarization using the collected data.

We propose a convolutional neural network (CNN) aided factor graphs assisted by mutual information features estimated by a neural network for seizure detection. Specifically, we use neural mutual information estimation to evaluate the correlation between different electroencephalogram (EEG) channels as features. We then use a 1D-CNN to extract extra features from the EEG signals and use both features to estimate the probability of a seizure event. Finally, learned factor graphs are employed to capture the temporal correlation in the signal.
