The article discusses the challenges associated with teaching NLP models and operationalizing ideas. It highlights the potential issues of shortcuts, overfitting, and interference with data or other concepts. Various methods for teaching models, such as utilizing subject matter experts, adversarial training, and adaptive testing, are discussed. The article also introduces the concept of Collaborative Development of NLP Models (CoDev), which involves multiple users working together to develop models that align with their beliefs. Experimental findings demonstrate the efficiency of CoDev in operationalizing concepts and managing interference.
NLP models have strengths but also face challenges. Teaching them specific ideas is important to avoid biases or failures. Traditional teaching methods involve introducing fresh training data that demonstrates the desired concepts. However, it is difficult to ensure that models don’t rely on shortcuts or overfit on the data.
One potential solution is to ask subject matter experts to provide comprehensive data that accurately represents the concept. Another method is to use adversarial training or adaptive testing, where users input data and get feedback from the model. However, these methods don’t directly address how different concepts interact with each other or with the original data.
Microsoft researchers propose the Collaborative Development of NLP Models (CoDev) approach. It utilizes the combined expertise of multiple users to cover various topics. They train both a local model for each concept and a global model that incorporates the initial data and additional ideas. The models are updated based on instances where they conflict.
Every local model is a specialist in its specific concept and is continuously improving. The CoDev approach makes it easier for users to investigate the boundaries between ideas and existing data. Experimental findings show that CoDev outperforms other methods in identifying and resolving issues in NLP models. It also helps operationalize ideas even when starting with biased data.
By using a simplified version of CoDev, where samples from unlabeled data are iteratively chosen, the selection process is compared to random selection and uncertainty sampling. CoDev proves to be more effective in teaching sentiment analysis and NLI models. Overall, CoDev assists users in refining their concepts and aligning the models with their beliefs.
