Annotation Cost Reduction of Stream-based Active Learning by Automated Weak Labeling using a Robot Arm

IROS 2021poster

Stream-based active learning (AL) is an efficient training data collection method, and it is used to reduce human annotation cost required in machine learning. However, it is difficult to say that the human cost is low enough because most previous studies have assumed that an oracle is a human with…

How Modular should Neural Module Networks Be for Systematic Generalization?

NeurIPS 2021poster

Neural Module Networks (NMNs) aim at Visual Question Answering (VQA) via composition of modules that tackle a sub-task. NMNs are a promising strategy to achieve systematic generalization, i.e., overcoming biasing factors in the training distribution. However, the aspects of NMNs that facilitate syst…

Rate-distortion optimization guided autoencoder for isometric embedding in Euclidean latent space

ICML 2020poster

To analyze high-dimensional and complex data in the real world, deep generative models, such as variational autoencoder (VAE) embed data in a low-dimensional space (latent space) and learn a probabilistic model in the latent space. However, they struggle to accurately reproduce the probability distr…
