Модель кодирования Word, чтобы сопоставить слова с индексами и назад
Слово, кодирующее слова карт в словаре к числовым индексам.
Чтобы закодировать документы как матрицы слова или количеств n-граммы, используйте encode.
enc = wordEncoding(documents)enc = wordEncoding(documents,Name,Value)enc = wordEncoding(documents,Name,Value)'Order','frequency' присваивает более низкие индексы более частым словам.
documents — Введите документыtokenizedDocumentВведите документы, заданные как массив tokenizedDocument.
Укажите необязательные аргументы в виде пар ""имя, значение"", разделенных запятыми. Имя (Name) — это имя аргумента, а значение (Value) — соответствующее значение. Name должен появиться в кавычках. Вы можете задать несколько аргументов в виде пар имен и значений в любом порядке, например: Name1, Value1, ..., NameN, ValueN.
'Order','frequency' сортирует индексы по общей частоте в документах в порядке убывания.'Order' — Сортировка индексов'first-seen' (значение по умолчанию) | 'frequency'Сортировка индексов, заданных как пара, разделенная запятой, состоящая из 'Order' и одно из следующего:
'first-seen' – Присвойте индексы словам в порядке, в котором они происходят в документах.
'frequency' – Присвойте индексы словам, отсортированным по общей частоте в документах в порядке убывания.
Если 'Order' является 'frequency', и несколько слов имеют ту же частоту, то функция не присваивает индексы ни в каком конкретном порядке.
'MaxNumWords' — Максимальное количество слов, чтобы закодироватьInf (значение по умолчанию) | положительное целое числоМаксимальное количество слов, чтобы закодировать, заданный как положительное целое число или Inf. Функциональные первые виды индексы согласно опции 'Order' и затем кодируют главные слова MaxNumWords. Если MaxNumWords является Inf, то функция кодирует все слова во входных документах.
NumWords — Количество слов в моделиКоличество слов в модели, заданной как неотрицательное целое число.
Vocabulary — Уникальные слова в моделиУникальные слова в модели, заданной как вектор строки.

1. Если смысл перевода понятен, то лучше оставьте как есть и не придирайтесь к словам, синонимам и тому подобному. О вкусах не спорим.
2. Не дополняйте перевод комментариями “от себя”. В исправлении не должно появляться дополнительных смыслов и комментариев, отсутствующих в оригинале. Такие правки не получится интегрировать в алгоритме автоматического перевода.
3. Сохраняйте структуру оригинального текста - например, не разбивайте одно предложение на два.
4. Не имеет смысла однотипное исправление перевода какого-то термина во всех предложениях. Исправляйте только в одном месте. Когда Вашу правку одобрят, это исправление будет алгоритмически распространено и на другие части документации.
5. По иным вопросам, например если надо исправить заблокированное для перевода слово, обратитесь к редакторам через форму технической поддержки.
