MDS6106Project

Final project of MDS6106 Optimization

• Solving variant-SVM and variant-Logistic Regression by implementing GM, AGM, BFGS, L-BFGS, SGD
• 4 self-generated data sets & some large-scale datasets from LIBSVM

To do list (Pytorch Version)

• Create to do list

• Generating Data

• Create Mini-Batch

• Solve Logistic Regression Problem from Scratch (In order to get some sense)

  • Initializing Model Parameters
  • Define the Model
  • Define the Loss Function
  • Define the Optimization Algorithm (SGD, first try simplest version)
  • Define Classification Accuracy and eval_accuracy for given model on specific dataset
  • Training
