Research being undertaken by Naveen Nair at the IITB-Monash Research Academy is looking at how to take sequence labeling to the next level, improving our understanding of how people perform activities and the relationship between each of their actions, so that the technology can become more efficient. For example, how can tasks be labeled in a smart home for the elderly so that it assists them by inferringtheir day to day actions.

Traditionally sequence labelling considers each action as part of a single variable and does not consider the overall context of the activity or the relationships between different actions that have been observed. Nair’s research focuses on finding the relationship between individual actions that have been observed. The learnings from these observations are then used to develop better inference models.

For example, each evening a person may open their bedroom door and then turn off the bedside heater. Where traditional sequence labeling would view these as two separate events, this research captures the relationship between the two actions, thereby resulting in a more meaningful system.

The system developed by Nair automatically learns such relationships in an efficient and optimal way.This information could be used to optimise the way devices are utilised in a smart home. Whereby, when a person opens (and closes) their bedroom door and turns off the bedside heater, the system infers that the person is going to sleep and automatically switches off the television in the living room.

The research being undertaken by Naveen Nair is under the guidance of Professors Ganesh Ramakrishnan (from the Indian Institute of Technology, Bombay, India) and Shonali Krishnaswamy (from Monash University, Australia). IITB-Monash Research Academy is a Joint Venture between the IITB and Monash. Opened in 2008, the IITB-Monash Research Academy is a graduate research school located in Mumbai that aims at enhancing research collaborations between Australia and India. Students study for a dual PhD from both institutions, and spend time during their research in both India and Australia.

The research will have a variety of practical applications according to Naveen Nair “As my research is based on learning optimum features for structured output, it will improve accuracy and can be used to perform efficient activity recognition. In the observations I have made with elderly people living alone, the inference model developed will be able to estimate the health of a person (as activities of daily living are indicators of health condition). It may also aid systems that optimise device utilization. Other potential applications for this technology may be as broad as in named entity recognition whereby more accurate identification of words within text are then used to extract journalistic articles.”

With its wide range of practical applications, such as labeling activities in a smart home so as to optimise the utlisation of each device and minimise power consumption, this research is very exciting and has the potential to stimulate new research with further application.
