\u3010Abstract\u3011
Exploring initial phases of astronomical transient events provides key insights
into their fundamental physical mechanisms, but choosing the right observation
mode immediately after discovery remains a challenge. In this seminar, we
present the Smart Kanata system, an automated decision-maker for optimal
follow-up observations of galactic transient, especially cataclysmic variables.
Using the Kanata 1.5-m telescope in Hiroshima, the system estimates event
class probability with a Bayesian classifier, determines the best observation
mode through mutual information, and controls the telescope and instruments
accordingly. This approach allows timely data collection for understanding the
object's nature, even without domain experts in the observatory. As a case study,
we explore early superhumps in WZ Sge-type dwarf novae, offering a unique
opportunity to reconstruct the geometrical structure of accretion disks using data
from the initial phase of the outburst.
