Kaggle Titanic solution 纯规则学习

其实就是把train.csv拿出来看了看,找了找规律,调了调参数而已。

找到如下规律:

1.男的容易死,女的容易活

2.一等舱活,三等舱死

3.老人死,小孩活

4.兄弟姐妹多者死

5.票价高的活

6.有Cabin记录的活

然后规则跑一跑,调一调参数,就把今天的提交次数用满了,然后跑到0.77了

    import pandas
import numpy
import csv

csv_reader = csv.reader(open('test.csv',encoding='utf-8'))
writer = csv.writer(open('ans.csv','w'))
writer.writerow(list(['PassengerID','Survived']))
data = []
A = 0
B = 0
for row in csv_reader:
	if(row[0][0]=='P'):
		continue
	now = 0
	#	一等舱获救,三等舱死亡
	if(row[1][0]=='1'):
		now=now+1;
	if(row[1][0]=='3'):
		now=now-1;

	#	男的死亡,女性获救
	if(row[3][0]=='f'):
		now=now+2;
	if(row[3][0]=='m'):
		now=now-1;

	#	老人死亡,年轻人获救
	if(len(row[4])>0):
		if(float(row[4])<=15):
			now=now+1;
		if(float(row[4])>=35):
			now=now-1;

	# 	兄弟姐妹多的死掉
	if(float(row[5])>1):
		now = now-1;

	#	财富高的活着,财富低的死亡
	if(len(row[8])>0):
		if(float(row[8])>100):
			now=now+1;
		if(float(row[8])<5):
			now=now-1;

	#	有Cabin的活着,无的死亡
	if(row[9] == None):
		now=now+1

	if(now>0):
		data.append([row[0],1])
		print([row[0],1,now])
		A = A + 1
	else:
		data.append([row[0],0])
		print([row[0],0,now])
		B = B + 1

print(A,B)
writer.writerows(data)
