.txt в .arff с помощью WEKA

Question

Я пытаюсь использовать этот набор данных в WEKA:

@relation adult 

@attribute age: continuous 

@attribute workclass: {Private,Self-emp-not-inc,Self-emp-inc,Federal-gov,Local-gov,State-gov,Without-pay,Never-worked} 

@attribute fnlwgt: continuous. 

@attribute education: {Bachelors,Some-college,11th,HS-grad,Prof-school,Assoc-acdm,Assoc-voc,9th,7th-8th,12th,Masters,1st-4th,10th,Doctorate,5th-6th,Preschool} 

@attribute education-num: continuous 

@attribute marital-status: {Married-civ-spouse,Divorced,Never-married,Separated,Widowed,Married-spouse-absent,Married-AF-spouse} 

@attribute occupation: {Tech-support,Craft-repair,Other-service,Sales,Exec-managerial,Prof-specialty,Handlers-cleaners,Machine-op-inspct,Adm-clerical,Farming-fishing,Transport-moving,Priv-house-serv,Protective-serv,Armed-Forces. 

@attribute relationship: {Wife,Own-child,Husband,Not-in-family,Other-relative,Unmarried} 

@attribute race: {White,Asian-Pac-Islander,Amer-Indian-Eskimo,Other,Black} 

@attribute sex: {Female,Male} 

@attribute capital-gain: continuous 

@attribute capital-loss: continuous 

@attribute hours-per-week: continuous 

@attribute native-country: {United-States,Cambodia,England,Puerto-Rico,Canada,Germany,Outlying-US(Guam-USVI-etc),India,Japan,Greece,South,China,Cuba,Iran,Honduras,Philippines,Italy,Poland,Jamaica,Vietnam,Mexico,Portugal,Ireland,France,Dominican-Republic,Laos,Ecuador,Taiwan,Haiti,Columbia,Hungary,Guatemala,Nicaragua,Scotland,Thailand,Yugoslavia,El-Salvador,Trinadad&Tobago,Peru,Hong,Holand-Netherlands} 

@data 

39,State-gov,77516,Bachelors,13,Never-married,Adm-clerical,Not-in-family,White,Male,2174,0,40,United-States,<=50K 

50,Self-emp-not-inc,83311,Bachelors,13,Married-civ-spouse,Exec-managerial,Husband,White,Male,0,0,13,United-States,<=50K 

38,Private,215646,HS-grad,9,Divorced,Handlers-cleaners,Not-in-family,White,Male,0,0,40,United-States,<=50K 

53,Private,234721,11th,7,Married-civ-spouse,Handlers-cleaners,Husband,Black,Male,0,0,40,United-States,<=50K 

28,Private,338409,Bachelors,13,Married-civ-spouse,Prof-specialty,Wife,Black,Female,0,0,40,Cuba,<=50K 

Я получаю ошибку:

Невозможно определить структуру, как ARFF (Причина: Java. io.IOException: ожидаемое значение ключевого слова @, прочитайте токен ['{'], строка 1). не

Который не имеет никакого смысла, потому что нет «{» в строке 1

Answer 1

Есть несколько вещей, которые могут быть причиной проблемы. Ниже приведены спецификации формата файла arff.

arff file format specifications

В приведенных ниже наборе данных, атрибуты, перечислены в следующем формате:

@attribute 'fnlwgt' real 

без двоеточия и реального/целого числа, а не непрерывно.

Кроме того, у вас есть

@attribute hours-per-week: continuous 

@attribute native-country: {United-States,Cambodia,England,Puerto-Rico,Canada,Germany,Outlying-US(Guam-USVI-etc),India,Japan,Greece,South,China,Cuba,Iran,Honduras,Philippines,Italy,Poland,Jamaica,Vietnam,Mexico,Portugal,Ireland,France,Dominican-Republic,Laos,Ecuador,Taiwan,Haiti,Columbia,Hungary,Guatemala,Nicaragua,Scotland,Thailand,Yugoslavia,El-Salvador,Trinadad&Tobago,Peru,Hong,Holand-Netherlands} 

Перевернутый в наборе данных.

39,State-gov,77516,Bachelors,13,Never-married,Adm-clerical,Not-in-family,White,Male,2174,0,40,United-States,<=50K 

И, вы не имеете

@attribute 'Class' {something, something2, something3}
