Embodiment Factors

Table: The embodiment factor is the ratio of compute to communicate in the model.

compute	\[\approx 100 \text{ gigaflops}\]	\[\approx 16 \text{ petaflops}\]
communicate	\[1 \text{ gigbit/s}\]	\[100 \text{ bit/s}\]
(compute/communicate)	\[10^{4}\]	\[10^{14}\]

DELVE Overview

DELVE will contribute data driven analysis to complement the evidence base informing the UK’s strategic response, by:

• Analysing national and international data to determine the effect of different measures and strategies on a range of public health, social and economic outcomes
• Using emerging sources of data as new evidence from the unfolding pandemic comes to light
• Ensuring that the work of this group is coordinated with others and communicated as necessary both nationally and internationally

Delve Timeline

• First contact 3rd April
• First meeting 7th April
• First working group 16th April

Data at the Heart

• Use data to answer policy questions.
• Make international comparisons for input.
• Challenges: around getting data.

What is Machine Learning?

\[ \text{data} + \text{model} \stackrel{\text{compute}}{\rightarrow} \text{prediction}\]

The Big Data Paradox

• We collect more data, but we understand less.

Wood or Tree

Big Model Paradox

• Add complexity to the model to make it realistic.
• Move model “beyond human intuition”
• But model still falls well short of mark in terms of representing reality

Increasing Need for Human Judgment

The domain of human judgment is increasing.

How these firms use knowledge. How do they generate ideas?

Data as a Convener

• Data allows externalisation of cognition.
• Even when not existing, can ask: What data would we want?

Delve Data Report

• Surveillance data situation.
  • REACT Study (Imperial)
  • ONS Coronavirus (COVID-19) Infection Survey
  • RECOVERY Trial (Dexamethasone)
• Happenstance data.
  • Our report’s focus (The DELVE Initiative, 2020g)

Delve Data Report: Recommendations

• Update statutory objective of ONS to accommodate happenstance data.
• ONS and ICO to collaborate on data driving license to standardise access processes.
• Interdisciplinary pathfinder projects across government, business and academia
  • Nowcasting of economic metrics
  • Movement of populations (mobile phone data).
