A Peg-in-hole Task Strategy for Holes in Concrete

no code implementations29 Mar 2024 André Yuji Yasutomi, Hiroki Mori, Tetsuya OGATA

Since the displacement increases as the peg gets closer to the hole (due to the chamfered shape of holes in concrete), it is a useful parameter for inputting in the DNN.

Visual Spatial Attention and Proprioceptive Data-Driven Reinforcement Learning for Robust Peg-in-Hole Task Under Variable Conditions

no code implementations27 Dec 2023 André Yuji Yasutomi, Hideyuki Ichiwara, Hiroshi Ito, Hiroki Mori, Tetsuya OGATA

In this study, we introduce a vision and proprioceptive data-driven robot control model for this task that is robust to challenging lighting and hole surface conditions.

A generative framework for conversational laughter: Its 'language model' and laughter sound synthesis

no code implementations6 Jun 2023 Hiroki Mori, Shunya Kimura

As the phonetic and acoustic manifestations of laughter in conversation are highly diverse, laughter synthesis should be capable of accommodating such diversity while maintaining high controllability.

Deep Active Visual Attention for Real-time Robot Motion Generation: Emergence of Tool-body Assimilation and Adaptive Tool-use

no code implementations29 Jun 2022 Hyogo Hiruma, Hiroshi Ito, Hiroki Mori, Tetsuya OGATA

The model incorporates a state-driven active top-down visual attention module, which acquires attentions that can actively change targets based on task states.

How to select and use tools? : Active Perception of Target Objects Using Multimodal Deep Learning

no code implementations4 Jun 2021 Namiko Saito, Tetsuya OGATA, Satoshi Funabashi, Hiroki Mori, Shigeki SUGANO

We also examine the contributions of images, force, and tactile data and show that learning a variety of multimodal information results in rich perception for tool use.

Embodying Pre-Trained Word Embeddings Through Robot Actions

no code implementations17 Apr 2021 Minori Toyoda, Kanata Suzuki, Hiroki Mori, Yoshihiko Hayashi, Tetsuya OGATA

These embeddings allow the robot to properly generate actions from unseen words that are not paired with actions in a dataset.

In-air Knotting of Rope using Dual-Arm Robot based on Deep Learning

1 code implementation17 Mar 2021 Kanata Suzuki, Momomi Kanamura, Yuki Suga, Hiroki Mori, Tetsuya OGATA

However, a manual description of appropriate robot motions corresponding to all object states is difficult to be prepared in advance.

Causal Patterns: Extraction of multiple causal relationships by Mixture of Probabilistic Partial Canonical Correlation Analysis

1 code implementation12 Dec 2017 Hiroki Mori, Keisuke Kawano, Hiroki Yokoyama

In this paper, we propose a mixture of probabilistic partial canonical correlation analysis (MPPCCA) that extracts the Causal Patterns from two multivariate time series.

Accuracy of Automatic Cross-Corpus Emotion Labeling for Conversational Speech Corpus Commonization

no code implementations LREC 2016 Hiroki Mori, Atsushi Nagaoka, Yoshiko Arimoto

There exists a major incompatibility in emotion labeling framework among emotional speech corpora, that is, category-based and dimension-based.
