Periodic Reporting for period 3 - INTERACT (Interactive Machine Learning for Compositional Models of Natural Language)

Sintesi del contesto e degli obiettivi generali del progetto

The goal of INTERACT is to develop interactive learning techniques so that we can train AI systems with minimal human supervision. The main focus is on applications in natural language processing such as automatic text classification. Currently, one of the main bottlenecks in training AI systems is the large amount of human annotated data required. Progress in achieving the goals of INTERACT will have an impact in the reach of AI technology. By reducing human annotation costs we wish to bring the power of customized AI systems to a larger public.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

We have done work in three main directions: 1) We have developed active learning algorithms for training machine learning models under annotation budget constraints and shown that they can significantly reduce the amount of annotated data necessary to achieve a given performance in some sequence classification benchmarks. 2) We have developed a novel model for semantic parsing specifically designed to improve generalization to unseen patterns that can be made by combining elements observed at training. We are currently working in developing active sampling strategies for this model. 3) We have studied the properties of word embeddings that best explain their performance in the few-shot learning scenario. We showed that the structural alignment between the space induced by a representation and the target class labels is critical. We are currently working on exploiting these insights to design efficient active sampling strategies for text classification. With respect to tools we have developed a software library for training linear deep-learning models and we have also started the development of a library for general low-rank matrix completion that will reduce several machine learning problems to matrix completion.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

Currently, most machine learning systems require large amounts of supervised training data in order to achieve reasonable performance. This is even more evident for complex tasks in natural language processing such as relation extraction or semantic parsing. This is because language is rich and complex and a good strategy for selecting the most informative pieces of data to annotate is needed. In INTERACT we expect to make a significant advancement on clever sampling strategies for learning complex functions in the context of natural language tasks, with these strategies we hope to achieve a drastic reduction in the amount of annotated data required to train a model.
