Why small and wide data is more relevant than big data

Gartner recently predicted that  70% of organisations by 2025 will shift their focus from big to small and wide data for more context for analytics and making AI less data hungry.

“Disruptions such as the pandemic is causing historical data that reflects past conditions to quickly become obsolete, which is breaking many production AI and machine learning (ML) models,” said Jim Hare, distinguished research vice president at Gartner. 

In addition, decision making by humans and AI has become more complex and demanding, and overly reliant on data hungry deep learning approaches, he noted.

D&A leaders need to turn to new analytics techniques knows as “small data” and “wide data”, Gartner advised. 

“Taken together they are capable of using available data more effectively, either by reducing the required volume or by extracting more value from unstructured, diverse data sources,” Hare said.

Small and wide Data allow more robust analytics and AI
Small data is an approach that requires less data but still offers useful insights, while including certain time-series analysis techniques or few-shot learning, synthetic data, or self-supervised learning, Gartner said. 

Wide data enables the analysis and synergy of a variety of small and large, unstructured, and structured data sources, the firm pointed out. 

It applies X analytics, with X standing for finding links between data sources, as well as for a diversity of data formats, Gartner explained. 

These formats include tabular, text, image, video, audio, voice, temperature, or even smell and vibration, the advisory firm added.

“Both approaches facilitate more robust analytics and AI, reducing an organisation’s dependency on big data and enabling a richer, more complete situational awareness or 360-degree view,” Hare pointed out. 

“D&A leaders apply both techniques to address challenges such as low availability of training data or developing more robust models by using a wider variety of data,” he said.

Potential applications
Potential areas where small and wide data can be used are demand forecasting in retail, real-time behavioural and emotional intelligence in customer service applied to hyper-personalisation, and customer experience improvement, Gartner predicted.

Other areas include physical security or fraud detection and adaptive autonomous systems, such as robots, which constantly learn by the analysis of correlations in time and space of events in different sensory channels, the firm added.
