Understanding what sequence of steps are needed to complete a goal can help artificial intelligence systems reason about human activities.Past work in NLP has examined the task of goal-step inference for text.We introduce the visual analogue.We propose the Visual Goal-Step Inference (VGSI) task, where a model is given a textual goal and must choose which of four images represents a plausible step towards that goal.With a new dataset harvested from wikiHow consisting of 772,277 images representing human actions, we show that our task is challenging for state-of-theart multimodal models.Moreover, the multimodal representation learned from our data can be effectively transferred to other datasets like HowTo100m, increasing the VGSI accuracy by 15 -20%.Our task will facilitate multimodal reasoning about procedural events.
