Overview
This notebook classifies movie reviews as positive or negative using the text of the review. This is an example of binary classification, an important and widely applicable kind of machine learning problem.
We will demonstrate the use of graph regularization in this notebook by building a graph from the given input. The general recipe for building a graph-regularized model using the Neural Structured Learning (NSL) framework when the input does not contain an explicit graph is as follows:
- Create embeddings for each text sample in the input. This can be done using pre-trained models such as word2vec, Swivel, BERT etc.
- Build a graph based on these embeddings by using a similarity metric such as the 'L2' distance, 'cosine' distance, etc. Nodes in the graph correspond to samples and edges in the graph correspond to similarity between pairs of samples.
- Generate training data from the above synthesized graph and sample features. The resulting training data will contain neighbor features in addition to the original node features.
- Create a neural network as a base model using Estimators.
- Wrap the base model with the
add_graph_regularization
wrapper function, which is provided by the NSL framework, to create a new graph Estimator model. This new model will include a graph regularization loss as the regularization term in its training objective. - Train and evaluate the graph Estimator model.
In this tutorial, we integrate the above workflow in a TFX pipeline using several custom TFX components as well as a custom graph-regularized trainer component.
Below is the schematic for our TFX pipeline. Orange boxes represent off-the-shelf TFX components and pink boxes represent custom TFX components.
Upgrade Pip
To avoid upgrading Pip in a system when running locally, check to make sure that we're running in Colab. Local systems can of course be upgraded separately.
import sys
if 'google.colab' in sys.modules:
!pip install --upgrade pip
Install Required Packages
!pip install -q \
tfx \
neural-structured-learning \
tensorflow-hub \
tensorflow-datasets
Did you restart the runtime?
If you are using Google Colab, the first time that you run the cell above, you must restart the runtime (Runtime > Restart runtime ...). This is because of the way that Colab loads packages.

IMDB dataset
The IMDB dataset contains the text of 50,000 movie reviews from the Internet Movie Database. These are split into 25,000 reviews for training and 25,000 reviews for testing. The training and testing sets are balanced, meaning they contain an equal number of positive and negative reviews. Moreover, there are 50,000 additional unlabeled movie reviews.
Download preprocessed IMDB dataset
The following code downloads the IMDB dataset (or uses a cached copy if it has already been downloaded) using TFDS. To speed up this notebook we will use only 10,000 labeled reviews and 10,000 unlabeled reviews for training, and 10,000 test reviews for evaluation.

"imdb_reviews:1.0.0",

print("Review: {}".format(tfrecord["text"].numpy().decode("utf-8")[:300]))
print("Label: {}\n".format(tfrecord["label"].numpy()))

Run TFX Components Interactively
In the cells that follow you will construct TFX components and run each one interactively within the InteractiveContext to obtain ExecutionResult
objects. This mirrors the process of an orchestrator running components in a TFX DAG based on when the dependencies for each component are met.

The IdentifyExamples Custom Component
To use NSL, we will need each instance to have a unique ID. We create a custom component that adds such a unique ID to all instances across all splits. We leverage Apache Beam to be able to easily scale to large datasets if needed.

The StatisticsGen Component
The StatisticsGen
component computes descriptive statistics for your dataset. The statistics that it generates can be visualized for review, and are used for example validation and to infer a schema.
Create a StatisticsGen component and run it.
# Computes statistics over data for visualization and example validation.
statistics_gen = StatisticsGen(

The SchemaGen Component
The SchemaGen
component generates a schema for your data based on the statistics from StatisticsGen. It tries to infer the data types of each of your features, and the ranges of legal values for categorical features.
Create a SchemaGen component and run it.
# Generates schema based on statistics files.
schema_gen = SchemaGen(
statistics=statistics_gen.outputs['statistics'], infer_feature_shape=False)

schema = tfx.utils.io_utils.parse_pbtxt_file(

It can be visualized using tfdv.display_schema()
(we will look at this in more detail in a subsequent lab):
tfdv.display_schema(schema)
The ExampleValidator Component
The ExampleValidator
performs anomaly detection, based on the statistics from StatisticsGen and the schema from SchemaGen. It looks for problems such as missing values, values of the wrong type, or categorical values outside of the domain of acceptable values.
Create an ExampleValidator component and run it.
# Performs anomaly detection based on statistics and data schema.
validate_stats = ExampleValidator(
statistics=statistics_gen.outputs['statistics'],
schema=schema_gen.outputs['schema'])
context.run(validate_stats, enable_cache=False)
The SynthesizeGraph Component
Graph construction involves creating embeddings for text samples and then using a similarity function to compare the embeddings.
We will use pretrained Swivel embeddings to create embeddings in the
tf.train.Example
format for each sample in the input. We will store the
resulting embeddings in the TFRecord
format along with the sample's ID.
This is important and will allow us match sample embeddings with corresponding
nodes in the graph later.
Once we have the sample embeddings, we will use them to build a similarity graph, i.e, nodes in this graph will correspond to samples and edges in this graph will correspond to similarity between pairs of nodes.
Neural Structured Learning provides a graph building library to build a graph based on sample embeddings. It uses cosine similarity as the similarity measure to compare embeddings and build edges between them. It also allows us to specify a similarity threshold, which can be used to discard dissimilar edges from the final graph. In the following example, using 0.99 as the similarity threshold, we end up with a graph that has 111,066 bi-directional edges.

The Transform Component
The Transform
component performs data transformations and feature engineering. The results include an input TensorFlow graph which is used during both training and serving to preprocess the data before training or inference. This graph becomes part of the SavedModel that is the result of model training. Since the same input graph is used for both training and serving, the preprocessing will always be the same, and only needs to be written once.
The Transform component requires more code than many other components because of the arbitrary complexity of the feature engineering that you may need for the data and/or model that you're working with. It requires code files to be available which define the processing needed.
Each sample will include the following three features:
- id: The node ID of the sample.
- text_xf: An int64 list containing word IDs.
- label_xf: A singleton int64 identifying the target class of the review: 0=negative, 1=positive.
Let's define a module containing the preprocessing_fn()
function that we will pass to the Transform
component:

The Transform
component has 2 types of outputs:
transform_graph
is the graph that can perform the preprocessing operations (this graph will be included in the serving and evaluation models).transformed_examples
represents the preprocessed training and evaluation data.
transform.outputs

Take a peek at the transform_graph
artifact: it points to a directory containing 3 subdirectories:
train_uri = transform.outputs['transform_graph'].get()[0].uri
os.listdir(train_uri)
['transform_fn', 'metadata', 'transformed_metadata']
The transform_fn
subdirectory contains the actual preprocessing graph. The metadata
subdirectory contains the schema of the original data. The transformed_metadata
subdirectory contains the schema of the preprocessed data.
Take a look at some of the transformed examples and check that they are indeed processed as intended.

The GraphAugmentation Component
Since we have the sample features and the synthesized graph, we can generate the augmented training data for Neural Structured Learning. The NSL framework provides a library to combine the graph and the sample features to produce the final training data for graph regularization. The resulting training data will include original sample features as well as features of their corresponding neighbors.
In this tutorial, we consider undirected edges and use a maximum of 3 neighbors per sample to augment training data with graph neighbors.

The Trainer Component
The Trainer
component trains models using TensorFlow.
Create a Python module containing a trainer_fn
function, which must return an estimator. If you prefer creating a Keras model, you can do so and then convert it to an estimator using keras.model_to_estimator()
.

3D to 2D. This fixed-length output vector is piped through a fully-connected

Model Serving
Graph regularization only affects the training workflow by adding a regularization term to the loss function. As a result, the model evaluation and serving workflows remain unchanged. It is for the same reason that we've also omitted downstream TFX components that typically come after the Trainer component like the Evaluator, Pusher, etc.
Conclusion
We have demonstrated the use of graph regularization using the Neural Structured Learning (NSL) framework in a TFX pipeline even when the input does not contain an explicit graph. We considered the task of sentiment classification of IMDB movie reviews for which we synthesized a similarity graph based on review embeddings. We encourage users to experiment further by using different embeddings for graph construction, varying hyperparameters, changing the amount of supervision, and by defining different model architectures.
