Learning Inter-Modal Correspondence and Phenotypes From Multi-Modal Electronic Health Records

چکیده
Non-negative tensor factorization has been shown a practical solution to automatically discover phenotypes from the electronic health records (EHR) with minimal human supervision. Such methods generally require an input describing inter-modal interactions be pre-established; however, correspondence between different modalities (e.g., medications and diagnoses) can often missing in practice. Although heuristic applied estimate them, they inevitably introduce errors, leads sub-optimal phenotype quality. This is particularly important for patients complex conditions critical care) as multiple diagnoses are simultaneously present records. To alleviate this problem EHR unobserved correspondence, we propose collective hidden interaction (cHITF) infer jointly discovery. We assume that observed matrix each modality marginalization of which reconstructed by maximizing likelihood matrices. Extensive experiments conducted on real-world MIMIC-III dataset demonstrate cHITF effectively infers clinically meaningful discovers more relevant diverse, achieves better predictive performance compared number state-of-the-art computational phenotyping models.

Deep Multi-Modal Image Correspondence Learning
Inference of correspondences between images from different modalities is an extremely important perceptual ability that enables humans to understand and recognize crossmodal concepts. In this paper, we consider an instance of this problem that involves matching photographs of building interiors with their corresponding floorplan. This is a particularly challenging problem because a floorplan, a...
متن کاملImportance of multi-modal approaches to effectively identify cataract cases from electronic health records
OBJECTIVE There is increasing interest in using electronic health records (EHRs) to identify subjects for genomic association studies, due in part to the availability of large amounts of clinical data and the expected cost efficiencies of subject identification. We describe the construction and validation of an EHR-based algorithm to identify subjects with age-related cataracts. MATERIALS AND...
متن کاملLearning Multi-modal Similarity
In many applications involving multi-media data, the definition of similarity between items is integral to several key tasks, e.g., nearest-neighbor retrieval, classification, and recommendation. Data in such regimes typically exhibits multiple modalities, such as acoustic and visual content of video. Integrating such heterogeneous data to form a holistic similarity space is therefore a key cha...
متن کاملLearning Concept Taxonomies from Multi-modal Data
We study the problem of automatically building hypernym taxonomies from textual and visual data. Previous works in taxonomy induction generally ignore the increasingly prominent visual data, which encode important perceptual semantics. Instead, we propose a probabilistic model for taxonomy induction by jointly leveraging text and images. To avoid hand-crafted feature engineering, we design end-...
