将转换字典转换为马尔可夫链中的转换矩阵的过程如下:
import numpy as np
def dict_to_transition_matrix(dictionary):
states = list(dictionary.keys())
num_states = len(states)
total_counts = np.zeros(num_states)
transition_matrix = np.zeros((num_states, num_states))
for i, state in enumerate(states):
total_counts[i] = sum(dictionary[state].values())
for i, state in enumerate(states):
for j, next_state in enumerate(states):
if next_state in dictionary[state]:
transition_matrix[i][j] = dictionary[state][next_state] / total_counts[i]
return transition_matrix
