Accomplishments

  • M.TECH
  • MAJOR PROJECT
  • An Ensemble of Deep Learning Models for detecting Invasive Ductal Carcinoma from Histopathological
  • Image
  • For classifying histopathological images into IDC and IDC - categories, four different deep CNNs
  • DenseNet, ResNet, Xception, and VGG19 are trained on histological images and to get advantages to every deep CNNs and optimize the model performance, both stacking and weighted average ensemble methods have been used
  • The ensembled loss function is also used for getting the advantages of each loss function
  • In this project, the proposed loss function is a combination of MAE, Hinge, and Binary
  • Cross-Entropy loss functions, leading to a more robust, generalized, and improved probability estimator respectively
  • B.TECH
  • MAJOR PROJECT
  • A web application on E-Governance
  • Use J2EE to implement an application for the collection of services like
  • Employment, Agriculture, Electricity, and Land Information.
