WebOct 8, 2024 · In light of our analysis, we devise an influence conflict detection -- based metric Totoro to measure the degree of graph topology imbalance and propose a model-agnostic method ReNode to address the topology-imbalance issue by re-weighting the influence of labeled nodes adaptively based on their relative positions to class boundaries. WebNov 3, 2024 · In this paper, we propose a novel motion forecasting model to learn lane graph representations and perform a complete set of actor-map interactions. Instead of using a rasterized map as input, we construct a lane graph from vectorized map data and propose the LaneGCN to extract map topology features. We use spatial attention and …
