Krishna:
Hi Group,
Milestone: Develop a local model using images generated by the diffusion model. – Oct 8
Following our discussion last week, I have been reviewing literature on approaches to improve the samples generated by the diffusion model.
My focus is primarily on research that utilizes the latent space of the diffusion model to create perturbations, as I believe this approach will be relevant for our project. I am also in process of implementing their code to generate images.
The paper is: https://ieeexplore.ieee.org/document/10581912

Dr. Lei:
the goal of this project is to improve the quality of the instances sampled for building high-fidelity local models. the quality will be in terms of realism of individual instances and representativeness of all the instances.
Dr. Lei:
Two specific things we discussed but I have not got a clear idea is: (1) what are the existing sampling approaches for building local models? are there fundamental differences between those for high accuracy and those for high fidelity? (2) are there any existing work on sampling from latent space to build local surrogate models? Can you make a presentation on this today or Friday’s meeting? Please try to focus on these two things.
Krishna:
I will give a presentation on Friday

Hi All,
Milestone: Build a local surrogate model using images generated using diffusion model – 9/27
Action Items Performed Last Week:
Results from Generated Perturbations:
Next Steps: Training a CNN based local model based on these generated images to explain the LRP based decision-making process.

Dr. Lei:
i don’t quite understand item 1. item 2 seems to be exactly what we would like. please explain the results in today’s meeting.
Krishna:
Hello All,
Milestone: Implement a baseline for local surrogate model
Action Items Done Last Week:
I plan on continuing my above tasks.

Dr. Lei:
can you put a target date on the milestone? also did you finish your survey/presentation on local surrogate model?
Krishna:
Hi All,
Milestone: Prepare a presentation on local model building for friday’s meeting.
I have been collecting and reviewing research papers regarding local surrogate model building.
I have prepared a presentation for tomorrow where I will present an approach to build local surrogate model using t-way tests and interpret a black box prediction for tabular data.

Dr. Lei:
look forward to the presentation tomorrow
