What should the format of the input dataset be for Google AutoML Natural Language multi-label text classification? I know that for multi-class classification I need a column of text and another column for labels. The labels column include one label per row.

I have multiple labels for each text and I want to do multi-label classification. I tried having one column per label and one-hot encoding but I got this error message: Max 1000 labels supported. Found 9823 labels.

It was very confusing at first but later I managed to find the format in the documentation, which is a CSV file like:

text1, label1, label2 text2, label2 text3, label3, label2, label1

The parser doesn't understand a table with NULL cells saved as a standard CSV file, which is like:

text1, label1, label2, text2, label2,, text3, label3, label2, label1

I had to manually remove extra commas from the CSV file generated by Pandas.

Preparing your training data | AutoML Natural Language, What should the format of the input dataset be for Google AutoML Natural Language multi-label text classification? I know that for multi-class classification I need  AutoML also has the functionality to work on Multi label classification Models. You can use this to predict all the labels that go with the text, and not just one label for each input text.

Google AutoML has updated their parser. The following format is fine:

text1, label1, label2, label3,
text1, label1, label2, ,
text1, label1, label2, , ,

At least that worked for me on 27th Jan 2019

One column per label is the way to go. If you have less than 1000 labels, you probably have a mistake in your CSV file, where the parser is getting confused and thinks some of the tokens in the text of the example are labels. Please make sure that your text is correctly escaped with quotes around.

Auto Text Classification using Google's AutoML, Natural language processing and within this automatic text classification into There should not be any duplicate text inputs, the model will give a warning if there is such a case. AutoML also has the functionality to work on Multi label classification Models. For this article, I will be using a news classification data set. Consider how AutoML Natural Language uses your dataset in creating a custom model Your dataset contains training, validation and testing sets. If you do not specify the splits (see Prepare Your Data ), then AutoML Natural Language automatically uses 80% of your content documents for training, 10% for validating, and 10% for testing.

AutoML Natural Language - AI Hub, AutoML Natural Language Beta enables you to train custom ML models with effort and machine learning expertise to classify content into a custom set of categories. Create labels to customize models for unique use cases using your own Text can be uploaded in the request or integrated with Google Cloud Storage. A dataset contains representative samples of the type of content you want to translate, as matching sentence pairs in the source and target languages. The dataset serves as the input for training a model. The main steps for building a dataset are: Create a dataset and identify the source and target languages.

Choosing between TensorFlow/Keras, BigQuery ML, and AutoML , Comparing text classification done three ways on Google Cloud Platform The training dataset comes from articles posted on Hacker News (there's a The first step is to launch Auto ML Natural Language from the GCP web console: and can deal with multi-class labels, but removing them is cleaner). To use the Cloud Natural Language API, you must to import the language module from the google-cloud-language library. The language.types module contains classes that are required for creating requests. The language.enums module is used to specify the type of the input text.

NLP With Google Cloud Natural Language API, Google has joined the natural language processing bandwagon with its Natural Language API and Google AutoML Natural Language. For example, for the input sentence “A computer once beat me at chess, but it was For classification and sentiment models, the datasets contain just two columns, the text and the label. This tutorial demonstrates how to create a custom model for classifying content using AutoML Natural Language. The application trains a custom model using a corpus of crowd-sourced "happy moments" from the Kaggle open-source dataset HappyDB.

  • Thanks a lot for the example and the details. We will add the "null" issue to our documentation.
  • Thank you @mona-attariyan for the answer. I found the answer later. For proper text display I added it an answer.
