BC03, 1 Sphere, Noise to PCL

Experiment with adding noise to point cloud. See here for visuals on what extra noise means to the point clouds, etc.

Overview

(06/06/2022) Running experiments where we are adding noise to the point clouds. Running 5X, after commit.
# 6D flow, but using SVD to extract actions, learning from >= 4DoF demos.
# As of 06/01/2022 this is serving as our 'proposed' method, WITH the
# consistency loss and WITHOUT the separate MLPs for (R,t).
SVD_POINTWISE_6D_EE2FLOW_SVD = dict(
obs_type='point_cloud',
act_type='ee2flow',
encoder_type='pointnet_svd_pointwise_6d_flow',
method_flow2act='svd',
use_consistency_loss=True,
lambda_consistency=0.1,
scale_pcl_flow=True,
scale_pcl_val=250,
separate_MLPs_R_t=False,
gaussian_noise_PCL=0.001, # normally 0
)
Should inspect the point cloud visualizations to see how much noise there is added.

(06/08/2022) This is strange, 2 runs crashed which is why two do not have the full curves here. HOWEVER, they seem to have actually run to completion on the cluster, so I just need to use my own script which should load in the complete files?

Left: no noise. Right: the noise scale of 0.001.
