Artificial intelligence (AI) is at the forefront of modern technology. Making AI “emotionally intelligent” could open doors to more natural human-machine interactions. To do this, it needs to pick up on the user’s sentiment during a dialog. Physiological signals could provide a direct route to such sentiments. Now, researchers from Japan take things to the next level with an AI with sentiment-sensing capabilities comparable to that of humans.

A Japanese research group found that the human sleep patterns could be classified into 16 types by combining ACCEL, their original machine learning algorithm for sleep-wake classification, the dimension reduction method and the clustering method. The acceleration data of approximately 100,000 people in the UK Biobank were analyzed in detail, and some life-style-related patterns and insomnia-like patterns were reported.

Earthquakes and other stressors on buildings pose a threat to their structural integrity that endangers human life. It is effective to be able to calculate the behavior of buildings and test with small-scale models. A shaking table test is an effective approach to characterize the seismic behavior of masonry structures. Models usually need to be reduced in scale due to their weight and the capacity of shaking tables.
