human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "automated identification of hookahs waterpipes on instagram an application in feature extraction using convolutional neural network and support vector machine classification"
  Abstract: Background#R##N#Instagram, with millions of posts per day, can be used to inform public health surveillance targets and policies. However, current research relying on image-based data often relies on hand coding of images, which is time-consuming and costly, ultimately limiting the scope of the study. Current best practices in automated image classification (eg, support vector machine (SVM), backpropagation neural network, and artificial neural network) are limited in their capacity to accurately distinguish between objects within images.

Connected through hyperedge HE-1 (induced by source paper "impact of imagenet model selection on domain adaptation"):
  with members:
    - "modified distribution alignment for domain adaptation with pre trained inception resnet"
    - "on minimum discrepancy estimation for deep domain adaptation"
    - "do better imagenet models transfer better"
    - "mobilenetv2 inverted residuals and linear bottlenecks"
    - "visual domain adaptation with manifold embedded distribution alignment"
    - "joint domain alignment and discriminative feature learning for unsupervised deep domain adaptation"
    - "balanced distribution adaptation for transfer learning"
    - "shufflenet an extremely efficient convolutional neural network for mobile devices"
