    Title] Generative Query Network as Meta-Learning

    Summary]
    Generative Query Network (GQN) is an innovative deep generative model that enables rendering of observed images from unknown viewpoints and has attracted attention as a new 3D modeling method. However, GQN is known to have some issues, such as a huge training cost and unstable training due to its sensitivity to hyperparameters. In addition, the lack of validation of GQN as a probabilistic model has hindered developmental research due to the low interpretability of the model architecture. To address these issues, we formulate a probabilistic model of GQN using a meta-learning framework and propose a method to improve the cost and instability of learning based on it. Evaluation experiments were conducted on the Shepard Metzler dataset to verify the effectiveness of the proposed method.
