![]() ![]() This is often done using tokenization techniques. To enable Natural Language Processing scenarios like Text Classification and Sentence Similarity, we needed a way to process text data. After training the model, you can provide source and target sentences and the model will predict the similarity between them.įor a more detailed example of the Sentence Similarity API, see the ML.NET 2.0 samples. To train a sentence similarity model, add the SentenceSimilarity trainer to your pipeline and call Fit. Similarity is defined by the value in the “Similarity” column which is a scale between 1 and 5 where 1 is least similar and 5 is most similar. In this example, a model is trained using sentences like “ML.NET 2.0 just released”, “There’s a new version of ML.NET”, and “The rain in Spain stays mainly in the plain” with the goal of predicting their similarity. The main difference though is instead of predicting a category, the model calculates a numerical value that represents how similar two phrases are. This API uses the same underlying TorchSharp NAS-BERT model as the Text Classification API. With ML.NET 2.0 we’ve also introduced a new API for sentence similarity. To get started with the Text Classification scenario, follow the sentiment analysis tutorial. For more details on setting up your GPU, see the ML.NET GPU guide. For GPUs you need a CUDA-compatible GPU and we recommend at least 6 GB of dedicated memory. This scenario supports local training on both CPU and GPU. With this new scenario, you can train custom text classification models using the latest deep learning techniques from Microsoft Research inside of Model Builder. Today we’re excited to announce the Text Classification scenario in Model Builder powered by the ML.NET Text Classification API. Since then, we’ve been working on refining the API. Using a pre-trained version of this model, the Text Classification API uses your data to fine-tune the model. It does so by integrating a TorchSharp implementation of NAS-BERT into ML.NET. As the name implies, this API enables you to train custom models that classify raw text data. Text Classification scenario in Model BuilderĪ few months ago we released a preview of the Text Classification API. ![]() To get started with these new features, install or upgrade to the latest versions of the ML.NET 2.0.0 and 0.20.0 packages as well as Model Builder 16.4.0 or later. You can find a list of all the changes in the respective ML.NET and Model Builder release notes. ![]() The following are highlights from this release. ML.NET version 2.0 and a new version of Model Builder are now released! What’s new? NET developers that enables integration of custom machine learning models into. So, we updated the code to make it a lot more efficient where all of these steps only happen once when using the Predict() method."Īchtman also provided an update on the dev team's efforts to address ML.NET "pain points" that were identified in a survey where users were asked about the biggest blockers/pain points/challenges reported by respondents when using ML.NET, as Visual Studio Magazine reported in June.ML.NET is an open-source, cross-platform machine learning framework for. "This resulted in decreased performance on each prediction. "In the previously generated model consumption code, these steps all happened inside the Predict() method, meaning that these all happened every time the Predict() method was called," Achtman said. Using the PredictionEngine and the model to make the prediction on the input data.When generated from the menu, a new notebook is empty.Īnother Model Builder update affects the Consumption file that gets generated during model training, containing a Predict() method which developers can use to make predictions with a model in an end-user application, effectively abstracting away several steps needed to consume an ML.NET model: Plots and graphs for data exploration and model explainability techniques so that devs can more easily understand and explain their data and model.The training pipeline for the model chosen by Model Builder so that developers can see how a model was trained, and easily re-train it.When generated from Model Builder, a notebook includes: It serves as one of two points of entry to use the new Notebook Editor tool, along with using the Add New Item dialog. Achtman discussed the notebook extension in the context of ML.NET's Model Builder, a UI tooling extension that leverages Automated Machine Learning (AutoML) to train and consume custom ML.NET models in. ![]()
