Curriculum Learning in NLP: Enhancing Model Performance by Structuring Training Data
Curriculum Learning (CL) is a training strategy in Natural Language Processing (NLP) that emphasizes the order of training instances, starting with simpler instances and gradually progressing to more complex ones. This approach mirrors how humans learn and can lead to improved model performance.
In the context of NLP, CL has been applied to various tasks such as sentiment analysis, text readability assessment, and few-shot text classification. By structuring the training data in a specific order, models can build on previously learned concepts, making it easier to tackle more complex tasks. This approach has been shown to be particularly beneficial for smaller models and when the amount of training data is limited.
Recent research has explored different aspects of CL, such as using SentiWordNet for sentiment analysis, developing readability assessment models for non-native English learners, and incorporating data augmentation techniques for few-shot text classification. These studies have demonstrated the effectiveness of CL in improving model performance across diverse NLP tasks.
Practical applications of CL in NLP include:
1. Sentiment Analysis: By ordering training instances based on their sentiment polarity, models can better understand and classify the sentiment of text segments.
2. Text Readability Assessment: CL can help develop models that accurately assess the readability of texts for non-native English learners, enabling the selection of appropriate reading materials.
3. Few-Shot Text Classification: CL, combined with data augmentation techniques, can improve the performance of models that classify text into multiple categories with limited training examples.
A company case study involving CL is LXPER Index, a readability assessment model for non-native English learners in the Korean ELT curriculum. By training the model with a curated text corpus, LXPER Index significantly improved the accuracy of readability assessment for texts in the Korean ELT curriculum.
In conclusion, Curriculum Learning offers a promising approach to enhance the performance of NLP models by structuring training data in a way that mirrors human learning. By starting with simpler instances and gradually progressing to more complex ones, models can build on previously learned concepts and tackle more challenging tasks with greater ease.

What is curriculum learning in machine learning?
Curriculum Learning (CL) is a training strategy in machine learning that structures the order of training instances, starting with simpler instances and gradually progressing to more complex ones. This approach mirrors how humans learn and can lead to improved model performance. In the context of Natural Language Processing (NLP), CL has been applied to various tasks such as sentiment analysis, text readability assessment, and few-shot text classification.
How is machine learning used in NLP?
Machine learning is used in NLP to develop models that can understand, interpret, and generate human language. These models are trained on large datasets containing text data and can perform tasks such as sentiment analysis, machine translation, text summarization, and question-answering. By learning patterns and structures in the text data, machine learning models can make predictions and generate outputs that are relevant to the given task.
What is an example of NLP machine learning?
An example of NLP machine learning is sentiment analysis, where a model is trained to classify the sentiment of a given text segment as positive, negative, or neutral. By using machine learning techniques, the model can learn to recognize patterns and features in the text data that are indicative of sentiment, such as specific words, phrases, or sentence structures.
What is NLP in deep learning?
NLP in deep learning refers to the application of deep learning techniques, such as neural networks, to natural language processing tasks. Deep learning models, like recurrent neural networks (RNNs) and transformers, are capable of handling complex language patterns and structures, making them well-suited for NLP tasks. These models can be used for tasks such as machine translation, text summarization, and sentiment analysis, among others.
