Agenda

  1. Data / Visualization framework in Python
    • API framework/usage guidelines
    • input  format
    • output format
    • Gui to inspect the data.
      • Original Data view
      • subsection view (using the rotated and subselected image parts).
      • Slider to adjust the time.
      • Play function.
      • Replay speed adjustment.
      • Basic statistics of the shown data (e.g. histogramms of the two images, min, max, mean, boxplots, number of blobs [1], …).
  2. Symmetry measurements
    • Develop measures and visualization tools to detect asymmetries between the two images.
    • Find examples of such asymmetries.
    • Analyze them.
  3. Occlusion removal
    • Classical CV approach
    • Learning-based approach(De-Occlusion)
  4. Abnormality detection
  5. Thesis writing

Topic 1: Data / Visualization framework in Python

Deliverables due to September

use pandas dataframe library

Topic 2: Symmetry measurements 

Deliverables due to October:

  • Develop automatic detection methods and selection tools for your guidance
    • e.g., highlight these events in your time-line in the gui with red bars, or create a list of events that can be selected

Topic 3: Occlusion removal

Concerned about its appicability to this project. we cannot assume it will work with non-face data

If we don’t know the dynamics of the liquid we cannot reconstruct maintaining the true underlying information.

due to November

Next Steps

  • Abnormality detection
    • due December
  • Thesis writing
    • due January

Next Meeting: TBA

Agenda

  • Presentation on Metallurgy review
  • Next Steps
    • Study dense NN
      • MNIST dataset
    • Study CNNs
      • Classification
      • Bounding Box
      • Segmentation

Topic 1: Presentation on Metallurgy review

Great introductory presentation on each book’s(3) content

No need to study the math on the properties of mixtures on the second book

Agenda

  • Present Paper Concept: Contrastive VAE
    • https://docs.google.com/presentation/d/1zBnog1A9mlHpZ4sFhwS12w6UBMrNYRfKgxCbLvcysUA/edit?usp=sharing

Topic 1: ConVAE

Present concept, math and next steps

Notes

  • Add an intermediate step in the introduction: “Why we want the latent representations”
  • Motivate Unsupervised Learning
  • Consider using a different distribution for the prior: L1 norm for example
  • What has changed in the behavior of the ConVAE in comparison with VAE from an Information Theory perspective
  • Mathematical proof that it can work in all datasets
  • Train later on ImageNet
