Python貝葉斯彩票是一種基于貝葉斯定理的彩票預測工具。通過收集歷史彩票數據,結合貝葉斯定理,建立概率模型,從而預測未來彩票的中獎概率。以下是一個Python實現的簡單例子。
import random def bayes_lottery(data, target): win_count = 0 total_count = len(data) for row in data: if row[-1] == target: win_count += 1 probability = win_count / float(total_count) return probability def predict_lottery(data, input_data): probabilities = {} for target in set([row[-1] for row in data]): probability = bayes_lottery(data, target) probabilities[target] = probability sorted_probabilities = sorted(probabilities.items(), key=lambda x: x[1], reverse=True) return sorted_probabilities[0] data = [[3, 1, 0], [2, 1, 0], [1, 1, 1], [1, 1, 1], [1, 0, 1]] input_data = [3, 1] prediction = predict_lottery(data, input_data) print('中獎概率最高的號碼:{}'.format(prediction[0]))
以上代碼中,bayes_lottery函數計算出給定數據集中某個目標(例如中獎號碼)的概率,predict_lottery函數則利用bayes_lottery函數,計算出每個目標的概率,最后返回概率最高的目標。運行結果為中獎概率最高的號碼:0。
