Grammatical error correction (GEC) attempts to model grammar and other types of writing errors in order to provide grammar and spelling suggestions, improving the quality of written output in documents, emails, blog posts and even informal chats. Over the past 15 years, there has been a substantial improvement in GEC quality, which can in large part be credited to recasting the problem as a “translation” task. When introduced in Google Docs, for example, this approach resulted in a significant increase in the number of accepted grammar correction suggestions.
One of the biggest challenges for GEC models, however, is data sparsity. Unlike other natural language processing (NLP) tasks, such as speech recognition and machine translation, there is very limited training data available for GEC, even for high-resource languages like English. A common remedy for this is to generate synthetic data using a range of techniques, from heuristic-based random word- or character-level corruptions to model-based approaches. However, such methods tend to be simplistic and do not reflect the true distribution of error types from actual users.
In “Synthetic Data Generation for Grammatical Error Correction with Tagged Corruption Models”, presented at the EACL 16th Workshop on Innovative Use of NLP for Building Educational Applications, we introduce tagged corruption models. Inspired by the popular back-translation data synthesis technique for machine translation, this approach enables the precise control of synthetic data generation, ensuring diverse outputs that are more consistent with the distribution of errors seen in practice. We used tagged corruption models to generate a new 200M sentence dataset, which we have released in order to provide researchers with realistic pre-training data for GEC. By integrating this new dataset into our training pipeline, we were able to significantly improve on GEC baselines.
Tagged Corruption Models
The idea behind applying a conventional corruption model to GEC is to begin with a grammatically correct sentence and then to “corrupt” it by adding errors. A corruption model can be easily trained by switching the source and target sentences in existing GEC datasets, a method that previous studies have shown that can be very effective for generating improved GEC datasets.
 |
| A conventional corruption model generates an ungrammatical sentence (red) given a clean input sentence (green). |
The tagged corruption model that we propose builds on this idea by taking a clean sentence as input along with an error type tag that describes the kind of error one wishes to reproduce. It then generates an ungrammatical version of the input sentence that contains the given error type. Choosing different error types for different sentences increases the diversity of corruptions compared to a conventional corruption model.
 |
| Tagged corruption models generate corruptions (red) for the clean input sentence (green) depending on the error type tag. A determiner error may lead to dropping the “a”, whereas a noun-inflection error may produce the incorrect plural “sheeps”. |
To use this model for data generation we first randomly selected 200M clean sentences from the C4 corpus, and assigned an error type tag to each sentence such that their relative frequencies matched the error type tag distribution of the small development set BEA-dev. Since BEA-dev is a carefully curated set that covers a wide range of different English proficiency levels, we expect its tag distribution to be representative for writing errors found in the wild. We then used a tagged corruption model to synthesize the source sentence.

The corrupted sentences are generated using a tagged corruption model by following the error type frequencies in the development set (bar chart). |
Results
In our experiments, tagged corruption models outperformed untagged corruption models on two standard development sets (CoNLL-13 and BEA-dev) by more than three F0.5-points (a standard metric in GEC research that combines precision and recall with more weight on precision), advancing the state-of-the-art on the two widely used academic test sets, CoNLL-14 and BEA-test.
In addition, the use of tagged corruption models not only yields gains on standard GEC test sets, it is also able to adapt GEC systems to the proficiency levels of users. This could be useful, for example, because the error tag distribution for native English writers often differs significantly from the distributions for non-native English speakers. For example, native speakers tend to make more punctuation and spelling mistakes, whereas determiner errors (e.g., missing or superfluous articles, like “a”, “an” or “the”) are more common in text from non-native writers.
Conclusion
Neural sequence models are notoriously data-hungry, but the availability of annotated training data for grammatical error correction is rare. Our new C4_200M corpus is a synthetic dataset containing diverse grammatical errors, which yields state-of-the-art performance when used to pre-train GEC systems. By releasing the dataset we hope to provide GEC researchers with a valuable resource to train strong baseline systems.

In the last post, we looked at how the GPU Operator has evolved, adding a rich feature set to handle GPU discovery, support for the new Multi-Instance GPU (MIG) capability of the NVIDIA Ampere Architecture, vGPU, and certification for use with Red Hat OpenShift.
In this post, we look at the new features added in the GPU Operator release 1.8, further simplifying GPU management for various deployment scenarios, inlcuding:
- Added support for GPU Operator upgrades
- Support for NVSwitch Systems, including DGX A100 and NVIDIA HGX A100 servers
- Support for gathering GPU Operator State Metrics
- GPU Operator and Network Operator Improve Multinode Training
- Support for Red Hat OpenShift 4.8
NVIDIA Software Lifecycle Management
Version 1.8 of GPU Operator provides an update mechanism for organizations to update their GPU Operator version without disrupting the workflow of the cluster the GPU Operator is running on. Previous releases of GPU Operator required users to uninstall the prior version before installing the new version, meaning no GPUs in the cluster were usable during the upgrade process.
Starting with 1.8, upgrading versions doesn’t disrupt the workflow. The mechanism updates one node at a time in a rolling fashion, so the other nodes can continue to be used. The next node is updated only when the installation is complete and the previous node is back online. Users can be confident that their workflow will be better managed when updating GPU Operator.
Now Supporting NVSwitch Systems
With 1.8, the GPU Operator automatically deploys the software required for initializing the fabric on NVIDIA NVSwitch systems, including the NVIDIA HGX A100 and DGX A100. Once initialized, all GPUs can communicate with one another at full NVLink bandwidth to create an end-end scalable computing platform.
The GPU Operator is also certified for use with Red Hat OpenShift 4 on DGX A100 systems.
Support for Gathering GPU Operator State Metrics
With 1.8, the GPU Operator now reports various metrics for users to monitor overall health of the GPU Operator and operator deployed resources under the gpu-operator-resources namespace. SRE teams and Cluster administrators can now configure necessary Prometheus resources to gather metrics and also to trigger alerts on certain failure conditions.
For the OpenShift Container Platform, these resources are automatically created in this release. Monitoring solutions like Grafana can be used to build dashboards and visualize the operational status of GPU Operator and node components.
Better Together: NVIDIA Accelerated Compute and Networking
Recently, NVIDIA announced the 1.0 release of the NVIDIA Network Operator. An analog to the NVIDIA GPU Operator, the Network Operator simplifies scale-out network design for Kubernetes by automating aspects of network deployment and configuration that would otherwise require manual work. It loads the required drivers, libraries, device plug-ins, and CNIs on any cluster node with an NVIDIA network interface.
When they are deployed together, the NVIDIA GPU and Network operators enable GPUDirect RDMA, a fast data path between NVIDIA GPUs on different nodes. This is a critical technology enabler for data-intensive workloads like AI Multi-Node Training.
