このチュートリアルでは、グラフから正則について説明ニューラル構造化学習の枠組みとTFXパイプラインにおける感情の分類のためのエンドツーエンドのワークフローを示しています。
概要
レビューのテキストを使用して、正または負としてこのノート分類の映画のレビュー。これは、バイナリ分類、機械学習、問題の重要かつ広く適用の種類の一例です。
与えられた入力からグラフを作成することにより、このノートブックでのグラフ正則化の使用法を示します。入力に明示的なグラフが含まれていない場合に、Neural Structured Learning(NSL)フレームワークを使用してグラフ正則化モデルを構築するための一般的なレシピは、次のとおりです。
- 入力のテキストサンプルごとに埋め込みを作成します。これは、次のような事前に訓練されたモデルで使用して行うことができますword2vec 、スイベル、 BERTなど
- 「L2」距離、「コサイン」距離などの類似性メトリックを使用して、これらの埋め込みに基づいてグラフを作成します。グラフのノードはサンプルに対応し、グラフのエッジはサンプルのペア間の類似性に対応します。
- 上記の合成グラフとサンプル特徴からトレーニングデータを生成します。結果のトレーニングデータには、元のノード機能に加えて隣接機能が含まれます。
- Estimatorを使用して、ベースモデルとしてニューラルネットワークを作成します。
- ベースモデルラップ
add_graph_regularization
新しいグラフ推定モデルを作成するために、NSLフレームワークによって提供されるラッパー関数を、。この新しいモデルには、トレーニング目標の正則化項としてグラフ正則化損失が含まれます。 - グラフ推定量モデルをトレーニングして評価します。
このチュートリアルでは、いくつかのカスタムTFXコンポーネントとカスタムグラフ正則化トレーナーコンポーネントを使用して、上記のワークフローをTFXパイプラインに統合します。
以下は、TFXパイプラインの概略図です。オレンジ色のボックスは既製のTFXコンポーネントを表し、ピンク色のボックスはカスタムTFXコンポーネントを表します。

IMDBのデータセットは、 50,000から映画のレビューのテキストが含まれ、インターネットムービーデータベースを。これらは、トレーニング用の25,000件のレビューとテスト用の25,000件のレビューに分けられます。トレーニングとテストセットは、それらが正と負のレビューの同じ番号が含ま意味、バランスされています。さらに、50,000件のラベルのない映画レビューが追加されています。

SynthesizeGraphコンポーネント
グラフの作成には、テキストサンプルの埋め込みを作成し、類似度関数を使用して埋め込みを比較することが含まれます。
私たちは中に埋め込みを作成するためにpretrainedスイベルの埋め込みを使用しますtf.train.Example
入力の各サンプルのためのフォーマット。私たちは、中の得られた埋め込み格納しますTFRecord
サンプルのIDと一緒にフォーマットを。これは重要であり、後でサンプルの埋め込みをグラフ内の対応するノードと一致させることができます。
サンプルの埋め込みができたら、それらを使用して類似性グラフを作成します。つまり、このグラフのノードはサンプルに対応し、このグラフのエッジはノードのペア間の類似性に対応します。
Neural Structured Learningは、サンプルの埋め込みに基づいてグラフを作成するためのグラフ作成ライブラリを提供します。これは、それらの間の埋め込みとビルドエッジを比較するために、類似性尺度としてコサイン類似度を使用しています。また、類似性のしきい値を指定することもできます。これを使用して、最終的なグラフから異なるエッジを破棄できます。次の例では、類似性のしきい値として0.99を使用すると、111,066の双方向エッジを持つグラフになります。

変換コンポーネント
Transform
コンポーネント行うデータ変換および機能エンジニアリング。結果には、トレーニングとトレーニングまたは推論の前にデータを前処理するために使用される入力TensorFlowグラフが含まれます。このグラフは、モデルトレーニングの結果であるSavedModelの一部になります。トレーニングとサービングの両方に同じ入力グラフが使用されるため、前処理は常に同じであり、1回だけ書き込む必要があります。
変換コンポーネントは、使用しているデータやモデルに必要な特徴エンジニアリングの任意の複雑さのために、他の多くのコンポーネントよりも多くのコードを必要とします。必要な処理を定義するコードファイルが利用可能である必要があります。
各サンプルには、次の3つの機能が含まれます。
- ID:サンプルのノードID。
- text_xf:単語IDを含むint64型の一覧。
- label_xf:0 =陰性、1 =正:AシングルトンのInt64レビューのターゲットクラスを識別する。

GraphAugmentationコンポーネント
サンプルの特徴と合成されたグラフがあるので、ニューラル構造化学習用の拡張トレーニングデータを生成できます。 NSLフレームワークは、グラフとサンプル機能を組み合わせて、グラフの正則化のための最終的なトレーニングデータを生成するためのライブラリを提供します。結果のトレーニングデータには、元のサンプル機能とそれに対応するネイバーの機能が含まれます。
このチュートリアルでは、無向エッジを考慮し、サンプルごとに最大3つのネイバーを使用して、グラフネイバーでトレーニングデータを拡張します。

# - vocab_size: This is the size of the vocabulary considered for this
# example.

# with its neighbors.
# - graph_regularization_multiplier: This controls the relative weight of the
# graph regularization term in the overall
# loss function.
# - num_neighbors: The number of neighbors used for graph regularization. This
# value has to be less than or equal to the `num_neighbors`
# argument used above in the GraphAugmentation component when

The layers are effectively stacked sequentially to build the classifier. The

The resulting dimensions are: (batch, sequence, embedding). Next is a global
average pooling 1D layer, which reduces the dimensionality of its inputs from
3D to 2D. This fixed-length output vector is piped through a fully-connected
(Dense) layer with 16 hidden units. The last layer is densely connected with a
single output node. Using the sigmoid activation function, this value is a
float between 0 and 1, representing a probability, or confidence level.

グラフの正則化は、損失関数に正則化項を追加することによってのみトレーニングワークフローに影響します。その結果、モデルの評価と提供のワークフローは変更されません。それは、我々はまた、一般的に、評価、プッシャーのようなトレーナーコンポーネントの後に来る下流TFX部品などを省略してきたのと同じ理由からです
結論
入力に明示的なグラフが含まれていない場合でも、TFXパイプラインでNeural Structured Learning(NSL)フレームワークを使用したグラフ正則化の使用を示しました。レビューの埋め込みに基づいて類似性グラフを合成したIMDB映画レビューの感情分類のタスクを検討しました。グラフの作成にさまざまな埋め込みを使用したり、ハイパーパラメータを変更したり、監視の量を変更したり、さまざまなモデルアーキテクチャを定義したりして、さらに実験することをお勧めします。
