چکیده
We present an automated approach for inferring surface geological structures from geophysical survey data. Our method employs machine learning, using mapped as labels and filtered surveys reference maps. compared the performance of eight main learning algorithms their 32 branches. Applied to Geological Survey Victoria's database Bendigo Zone, following appropriate choice features, 3-class classification model subspace K-nearest neighbour methods achieves a stable validated 92% accuracy in around 1 min. The fault-only 97% 6 This shows that structural features on may be inferred between one three data types: gravity, airborne total magnetic intensity first vertical derivative intensity. It prospect research suggests combined with useful efficient determining existence features.

The southern Alaska magnetic trough (SAMT) is one of the fundamental, crustal-scale, magnetic features of Alaska. It is readily recognized on 10 km upward-continued aeromagnetic maps of the state. The arcuate SAMT ranges from 30 to 100 km wide and extends in two separate segments along the southern Alaska margin for about 1200 km onshore (from near the Alaska/Canada border at about 60 degrees n...

Heart is one of the most important members of the body, and heart disease is the major cause of death in the world and Iran. This is why the early/on time diagnosis is one of the significant basics for preventing and reducing deaths of this disease. So far, many studies have been done on heart disease with the aim of prediction, diagnosis, and treatment. However, most of them have been mostly f...
متن کاملGeological Field Mapping
A map showing the distribution of rock units and structures across a region representation, usually on a plane surface is termed a geological map. A map showing the occurrence of structural features across a region, the distribution of rock units, and their type and age relationship is termed a geological map. Geological field mapping is the process of selecting an area of interest and identify...
