wordEncoding

単語からインデックスへのマッピングとその逆変換のための単語符号化モデル

このページをすべて展開する

説明

単語符号化は、ボキャブラリ中の単語を数値インデックスにマッピングします。

文書を単語または n-gram のカウントの行列として符号化するには、encode を使用します。

作成

構文

enc = wordEncoding(documents)
enc = wordEncoding(words)
enc = wordEncoding(documents,Name,Value)

説明

enc = wordEncoding(documents) は、documents 内の単語から単語符号化を作成します。

例

enc = wordEncoding(words) は、単語の配列から単語符号化を作成します。

例

enc = wordEncoding(documents,Name,Value) は、1 つ以上の名前と値のペアの引数を使用して、追加のオプションを指定します。たとえば、'Order','frequency' は、出現頻度の高い単語に対して、より小さなインデックスを割り当てます。

例

入力引数

すべて展開する

入力文書。tokenizedDocument 配列として指定します。

入力単語。string ベクトル、文字ベクトル、または文字ベクトルの cell 配列として指定します。words を文字ベクトルとして指定した場合、関数は引数を 1 つの単語として扱います。

データ型: string | char | cell

名前と値の引数

すべて展開する

オプションの引数のペアを Name1=Value1,...,NameN=ValueN として指定します。ここで、Name は引数名で、Value は対応する値です。名前と値の引数は他の引数の後に指定しなければなりませんが、ペアの順序は重要ではありません。

R2021a より前では、コンマを使用して名前と値をそれぞれ区切り、Name を引用符で囲みます。

例: 'Order','frequency' は、文書内の総出現頻度に基づいてインデックスを降順に並べ替えます。

インデックスの並べ替え。'Order' と次のいずれかで構成されるコンマ区切りのペアとして指定します。

  • 'first-seen' – 文書内で出現する順序で単語にインデックスを割り当てます。

  • 'frequency' – 文書内の総出現頻度の降順で並べ替えた単語にインデックスを割り当てます。

'Order' が 'frequency' であり、複数の単語の頻度が同じ場合、関数は特定の順序でインデックスを割り当てることはしません。

符号化する単語の最大数。正の整数または Inf として指定します。関数はまず 'Order' オプションに従ってインデックスを並べ替え、次に上位 MaxNumWords 個の単語を符号化します。MaxNumWords が Inf である場合、この関数は入力文書内のすべての単語を符号化します。

プロパティ

すべて展開する

モデル内の一意の単語の数。非負の整数として指定します。

モデル内の一意の単語。string ベクトルとして指定します。

単語埋め込みから単語符号化を作成するには、単語埋め込みボキャブラリを単語のリストとして wordEncoding 関数に入力します。

事前学習済みの単語埋め込みを読み込みます。

emb = fastTextWordEmbedding;

ボキャブラリを抽出します。

words = emb.Vocabulary;

ボキャブラリを使用して単語符号化を作成します。

深層学習ネットワーク内の対応する単語埋め込み層を単語埋め込みの重みで初期化するには、word2vec 関数を使用して層の重みを抽出し、wordEmbeddingLayer 関数の名前と値のペア 'Weights' を設定します。単語埋め込み層が必要とするのは単語ベクトルの列であるため、関数 word2vec の出力は転置しなければなりません。
