2D shape synthetic data generation

[songfeng]

• images - reference
  https://github.com/alsuhr-c/nlvr-baselines

• instruction patterns / dialog acts - randomly generated instructions with(out) image references?
  TEXT PATTERN || ACTIONS || RESULTED LAYOUT
  draw a {color} {shape} // new // obj1-(x, y)
  place a {color} {shape} to the left of obj1 // new // obj1-(x,y), obj2-(x-1, y)

• added gold and noise - evaluate painters' actions
  e.g., add {obj1} above {obj2} while {obj2} is missing
