The notion of randomness, prediction and probability based on algorithmic information theory and computable analysis
Algorithmic Information Theory gives the definition of complexity of a concrete object. Then the notion of randomness (algorithmic randomness) and the notion of prediction and probability (algorithmic probability) have been studied. By combining with computable analysis developed especially recently, I try to study the notion in detail.
