The importance of National Statistics Day in India, and the remarkable contributions of Prof. Prasanta Chandra Mahalanobis to national planning and data analytics, cannot be underscored enough. Mahalanobis, also known as the ‘Plan Man’ of India, has significant relevance even today, especially as India strives to navigate through the complexities of Big Data and the transformative power of artificial intelligence (AI). Reflecting on his methods and strategies can provide valuable insights on effectively dealing with these modern challenges.
Prof, P.C. Mahalanobis: A Pioneering Contributor to National Development
Born in Calcutta (now Kolkata), the grandson of Gurucharan, a social reformer and disciple of Debendranath Tagore, Prof. P.C. Mahalanobis, made significant strides in the field of data collection, analysis, and planning for national development. His legacy began in 1931 with the establishment of the Indian Statistical Institute (ISI) in Calcutta, which aimed to promote research and education in statistics and related fields.
In 1933, Mahalanobis founded Sankhya, the first Indian statistical journal. His contributions to the nation didn’t stop there. In 1955, appointed by Prime Minister Jawaharlal Nehru, he became a member of the Planning Commission of India, playing a critical role in designing India’s strategy for industrialisation and economic growth in the Second Five-Year Plan (1956-61). This plan, also famously known as the Mahalanobis Plan, was based on his mathematical model emphasising heavy industries and capital goods. Beyond his contributions to statistics, Mahalanobis is also noted for his involvement in shaping Rabindranath Tagore’s Visva Bharati University. In acknowledgement of his exceptional contributions, he was awarded the Padma Vibhushan in 1968.
Implementing Mahalanobis’s Approach to Tackle Big Data and AI Challenges
Mahalanobis’s methods offer significant insights to regulate AI and confront the associated challenges, such as job displacement, ethical dilemmas and the spread of misinformation. His practice of incorporating built-in cross-checks in his surveys, echoed from Kautilya’s Arthashastra, underscores the importance of ensuring data integrity. This approach highlights the crucial need for rigorous data preprocessing and the establishment of fairness in AI algorithms.
Applying this method means assessing and mitigating biases when deploying AI in processes like hiring, thereby enabling equal opportunities for all candidates. Recognizing and addressing these challenges is essential for creating responsible and inclusive AI systems.
Integrating Multiple Data Sources in Big Data and AI
Mahalanobis consistently advocated integrating diverse data sources to capture a comprehensive snapshot of the economy and society. Translated into the context of Big Data and AI, this involves incorporating various data streams, such as structured and unstructured data, social media inputs, satellite imagery, and sensor readings.
This integration can facilitate comprehensive analyses and drive innovative applications. In agriculture, for instance, the combination of weather data, satellite images, and farmer-generated data can offer valuable insights on crop health, pest outbreaks and best irrigation practices. Consequently, AI-driven solutions like precision agriculture can be developed, improving crop yields and enhancing farmers’ livelihoods.
The Pertinence of Statistical Models
For Mahalanobis, statistical models were crucial in deriving meaningful inferences and predictions. With the advent of Big Data and AI, advanced machine learning algorithms and predictive modelling techniques have assumed a key role in analysing voluminous datasets.
These models can find application across diverse domains, such as healthcare, finance, and urban planning. For example, applying predictive models to healthcare data enables policymakers to identify population health trends, predict potential disease outbreaks and allocate resources more effectively. This approach thus facilitates evidence-based decision making and proactive interventions.
The teachings and principles of Mahalanobis continue to guide modern analytics and AI, his pioneering drive for data integrity and comprehensive analyses resonate in today’s data-driven landscape, proving his timeless relevance.
