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.
Procedural events can often be thought of as a high level goal composed of a sequence of steps. Inferring the sub-sequence of steps of 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 a plausible step towards that goal from among four candidate images. Our task is challenging for state-of-the-art muitimodal models. We introduce a novel dataset harvested from wikiHow that consists of 772,294 images representing human actions. We show that the knowledge learned from our data can effectively transfer to other datasets like HowTo100M, increasing the multiple-choice accuracy by 15% to 20%. Our task will facilitate multi-modal reasoning about procedural events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
