# Self-Consistency

Одним из более продвинутых методов оптимизации запросов является метод самосогласованности. Предложенный в [Wang et al. (2022)](https://arxiv.org/pdf/2203.11171.pdf), метод самосогласованности стремится "заменить простую жадную декодировку, используемую в методе few-shot CoT". Идея заключается в выборе нескольких различных путей рассуждения через метод few-shot CoT, а затем использовании генераций для выбора наиболее согласованного ответа. Это помогает улучшить производительность CoT-метода в задачах, связанных с арифметикой и здравым смыслом.
|
|||
|
|
|
|||
|
|
Давайте попробуем следующий пример для арифметического рассуждения:
|
|||
|
|
|
|||
|
|
*Запрос:*
|
|||
|
|
```
|
|||
|
|
When I was 6 my sister was half my age. Now
|
|||
|
|
I’m 70 how old is my sister?
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
*Результат:*
|
|||
|
|
```
|
|||
|
|
35
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Ответ неверный! Как можно улучшить результат с помощью метода самосогласованности? Давайте попробуем. Мы будем использовать примеры с малым количеством данных из работы Wang et al. 2022 (Таблица 17):
|
|||
|
|
|
|||
|
|
*Запрос:*
|
|||
|
|
```
|
|||
|
|
Q: There are 15 trees in the grove. Grove workers will plant trees in the grove today. After they are done,
|
|||
|
|
there will be 21 trees. How many trees did the grove workers plant today?
|
|||
|
|
A: We start with 15 trees. Later we have 21 trees. The difference must be the number of trees they planted.
|
|||
|
|
So, they must have planted 21 - 15 = 6 trees. The answer is 6.
|

|
|
|||
|
|
Q: If there are 3 cars in the parking lot and 2 more cars arrive, how many cars are in the parking lot?
|
|||
|
|
A: There are 3 cars in the parking lot already. 2 more arrive. Now there are 3 + 2 = 5 cars. The answer is 5.

|
|
Q: Leah had 32 chocolates and her sister had 42. If they ate 35, how many pieces do they have left in total?
|
|||
|
|
A: Leah had 32 chocolates and Leah’s sister had 42. That means there were originally 32 + 42 = 74
|
|||
|
|
chocolates. 35 have been eaten. So in total they still have 74 - 35 = 39 chocolates. The answer is 39.
|

|
|

|
|
Q: Jason had 20 lollipops. He gave Denny some lollipops. Now Jason has 12 lollipops. How many lollipops
|
|||
|
|
did Jason give to Denny?
|
|||
|
|
A: Jason had 20 lollipops. Since he only has 12 now, he must have given the rest to Denny. The number of
|
|||
|
|
lollipops he has given to Denny must have been 20 - 12 = 8 lollipops. The answer is 8.

|
|
Q: Shawn has five toys. For Christmas, he got two toys each from his mom and dad. How many toys does
|
|||
|
|
he have now?
|
|||
|
|
A: He has 5 toys. He got 2 from mom, so after that he has 5 + 2 = 7 toys. Then he got 2 more from dad, so
|
|||
|
|
in total he has 7 + 2 = 9 toys. The answer is 9.

|
Q: There were nine computers in the server room. Five more computers were installed each day, from
|
|||
|
|
monday to thursday. How many computers are now in the server room?
|
|||
|
|
A: There are 4 days from monday to thursday. 5 computers were added each day. That means in total 4 * 5 =
|
|||
|
|
20 computers were added. There were 9 computers in the beginning, so now there are 9 + 20 = 29 computers.
|
|||
|
|
The answer is 29.

Q: Michael had 58 golf balls. On tuesday, he lost 23 golf balls. On wednesday, he lost 2 more. How many
|
|||
|
|
golf balls did he have at the end of wednesday?
|
|||
|
|
A: Michael initially had 58 balls. He lost 23 on Tuesday, so after that he has 58 - 23 = 35 balls. On
|
|||
|
|
Wednesday he lost 2 more so now he has 35 - 2 = 33 balls. The answer is 33.

Q: When I was 6 my sister was half my age. Now I’m 70 how old is my sister?
|
|||
|
|
A:
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
*Результат 1:*
|
|||
|
|
```
|
|||
|
|
When I was 6 my sister was half my age, so she was 3. Now I am 70, so she is 70 - 3 = 67. The answer is 67.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
*Результат 2:*
|
|||
|
|
```
|
|||
|
|
When the narrator was 6, his sister was half his age, which is 3. Now that the narrator is 70, his sister would be 70 - 3 = 67 years old. The answer is 67.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
*Результат 3:*
|
|||
|
|
```
|
|||
|
|
When I was 6 my sister was half my age, so she was 3. Now I am 70, so she is 70/2 = 35. The answer is 35.

Вычисление конечного ответа включает несколько шагов (подробности смотрите в статье), но для простоты можно заметить, что уже появляется преобладающий ответ, который становится окончательным.
