Abstract

Association rules is a very important part of data mining. It is used to find the interesting patterns from transaction databases. Apriori algorithm is one of the most classical algorithms of association rules, but it has the bottleneck in efficiency. In this article, we proposed a prefixed-itemset-based data structure for candidate itemset generation, with the help of the structure we managed to improve the efficiency of the classical Apriori algorithm., Comment: 9 pages, 2 figures

Abstract

The original intention of visual question answering (VQA) models is to infer the answer based on the relevant information of the question text in the visual image, but many VQA models often yield answers that are biased by some prior knowledge, especially the language priors. This paper proposes a mitigation model called language priors mitigation-VQA (LPM-VQA) for the language priors problem in VQA model, which divides language priors into positive and negative language priors. Different network branches are used to capture and process the different priors to achieve the purpose of mitigating language priors. A dynamically-changing language prior feedback objective function is designed with the intermediate results of some modules in the VQA model. The weight of the loss value for each answer is dynamically set according to the strength of its language priors to balance its proportion in the total VQA loss to further mitigate the language priors. This model does not depend on the baseline VQA architectures and can be configured like a plug-in to improve the performance of the model over most existing VQA models. The experimental results show that the proposed model is general and effective, achieving state-of-the-art accuracy in the VQA-CP v2 dataset. [ABSTRACT FROM AUTHOR]

31. Sentiment Lexicon Construction Based on Improved Left-Right Entropy Algorithm.

Abstract

A novel method of constructing sentiment lexicon of new words (SLNW) is proposed to realize effective Weibo sentiment analysis by integrating existing lexicons of sentiments, lexicons of degree, negation and network. Based on left-right entropy and mutual information (MI) neologism discovery algorithms, this new algorithm divides N-gram to obtain strings dynamically instead of relying on fixed sliding window when using Trie as data structure. The sentiment-oriented point mutual information (SO-PMI) algorithm with Laplacian smoothing is used to distinguish sentiment tendency of new words found in the data set to form SLNW by putting new words to basic sentiment lexicon. Experiments show that the sentiment analysis based on SLNW performs better than others. Precision, recall and F-measure are improved in both topic and non-topic Weibo data sets.
