Cosmology with Large scale structure using Machine Learning(CLML)

• Ω_m, σ_8 → 512_short
• 1116 data
• Lines and histograms are inversely proportional.
• Dark matter halos : Agglomeration of particles, Processed information
• Dark matter particles : Initial number of particles setting, Original information
• Add mass information
• Add velocity information
• Can cosmological parameters be determined as input data?
  • Maybe it can decide.

5 Hannah's Report - Weak Lensing with Machine Learning

Speaker: Hannah Jhee (University of Seoul)

Weak Lensing with Machine Learning(GAN)

• It works well if you match all of them with true or false.
• It needs to design the descrimanator carefully and well with multitasking.
• Therefore, better results may be obtained if the noise-free data is identified as having noise.

6 Dr.Sabiu's Report - N-PCF

Speaker: Dr Cristiano Sabiu (University of Seoul)
