Balaji is a Principal Scientist at Adobe Research, India. His current research interests span the areas of natural language generation and multimodal content synthesis towards automating enterprise authoring workflows. In the past, he has worked on problems in text mining, social data analytics, high performance computing, scalable machine learning and speaker recognition.
Multimodal Content Synthesis: The experience that is consumed in various digital media involves multiple content modalities. In this line of work, the key focus is on understanding the impact of different modalities in conveying a target information and utilizing the understanding to synthesize appropriate multimodal content combination to deliver the right experience for the target medium and user need. While existing research are often limited to a single modality, this research aims to look at the combinations of different modalities and the challenges that ensues.
Tailored Natural Language Generation: There has been a growing interest in language modelling for several downstream application. Here, the key focus is to generate text that is tailored (both informationally and stylistically) to various enterprise needs. Existing works rely on the availability of parallel corpus for training end-to-end models for such task. However, our research tries to explore low resource scenarios to enable scaling of these models to enterprise settings where parallel data may not be readily available.
Causal Impacts of Content on Consumption: Enterprise content are often written to achieve certain business goals. Here, the focus is to get a holistic understanding of how a content’s information and style impacts its business goals. Our research explores causal modelling to bridge the content’s performances to its presentation, to empower marketers and copywriters towards creating impactful content.
Explainability & Interpretability in Generation: A key towards reliable adoption of automatic workflows is for the models to become more explainable and interpretable. While a large focus in NLP is to use attention (and/or other mid-layer representations) to be interpretable, they are limited to text classification and natural language inference tasks. Our research here focuses on exploring ways to make neural generation more explainable and interpretable.
