tailieunhanh - Single concatenated input is better than indenpendent multiple input for CNNs to Predict chemical-induced disease relation from literature

This paper demonstrates that for a CNN it is vice-versa, in which concatenation is better for CDR classification. To this end, we develop a CNN based model with multiple input concatenated for CDR classification. Experimental results on the benchmark dataset demonstrate its outperformance over other recent state-of-the-art CDR classification models. | VNU Journal of Science Comp. Science amp Com.

Working with PubMed is essential for researchers to get insights into drugs side effects chemical-induced disease relations CDR which is essential for drug safety and toxicity. It is however a catastrophic burden for them as PubMed is a huge database of unstructured texts growing steadily very fast 28 millions scientific articles currently approximately two deposited per minute . As a result biomedical text mining has been empirically demonstrated its great implications in biomedical research communities. Biomedical text has its own distinct challenging properties attracting much attetion from natural language processing communities. A large-scale study recently in 2018 showed that incorporating information into indenpendent multiple-input layers outperforms concatenating them into a single input layer for biLSTM producing better performance when compared to state-of-the-art CDR classifying models. This paper demonstrates that for a CNN it is vice-versa in which concatenation is better for CDR classification. To this end we develop a CNN based model with multiple input concatenated for CDR classification. Experimental results on the benchmark dataset demonstrate its outperformance over other recent state-of-the-art CDR classification .
