Rabbit, toad, and the Moon: Can machine categorize them into one class?
Daigo Shoji
Recent machine learning algorithms such as neural networks can classify objects and actions in video frames with high accuracy. Here, I discuss a classification of objects based on…
Enceladus Farm: Can plants grow with Enceladus' water? (Preliminary Report)
Daigo Shoji
Enceladus is a saturnian satellite that should have liquid water inside of it (subsurface ocean). Measurements and experiments on water plume from Enceladus have revealed that Ence…
Angle of repose of Martian wet sand using discrete element method: Implication for the seasonal cycle of recurring slope lineae(RSL) by relative humidity
Daigo Shoji, Shoko Imamura, Maya Nakamura +1
Seasonal cycle of Martian relative humidity shows that, in the southern and the northern RSL sites, humidity decreases when RSL increment while humidity is high on the fading seaso…
Condition for the deflection of vertical cracks at dissimilar ice interfaces on Europa
Daigo Shoji
The surface of Europa contains many quasi-circular morphologies called lenticulae. Although the formation mechanism of lenticulae is not understood, sill intrusion from the subsurf…
Classification of volcanic ash particles using a convolutional neural network and probability
Daigo Shoji, Rina Noguchi, Shizuka Otsuki +1
Analyses of volcanic ash are typically performed either by qualitatively classifying ash particles by eye or by quantitatively parameterizing its shape and texture. While complex s…
What does a convolutional neural network recognize in the moon?
Daigo Shoji
Many people see a human face or animals in the pattern of the maria on the moon. Although the pattern corresponds to the actual variation in composition of the lunar surface, the c…
