Large data becomes unwieldly

“Data is our strategic asset”

Only when we can extract actionable insights.  Data first needs to be cleaned, structured, enriched, then modelled.

Location data

• Address matched to other sources is powerful.  E.g. Census – Challenge: how to make sense of so much data

• Clustering is useful to find patterns in location for a customer base– Take a large number of variables (Census and internal data)– Find what data points occur together frequently, or are correlated– Assign them to a group– We now have a manageable and rich data set

Seasonality modelling

Requires two years of data for each customer

Behavioural clustering

Seasonality

LocationIndustry

1. Train seasonality models where we can (2 years of data)

2. Cluster customers by seasonality

3. Predict seasonality cluster by Industry and Location groups

4. Infer the trend

We now know the amount to lend

Signal and noise

We can get a lot of data this way, but how much is really useful?

• Need to ensure it is reliable• Must be collected over time (can take many months)• Machine learning is key to determine useful variables• Constructing reliable outcomes is critical. E.g.

– Rapid growth– Fraud– Bankruptcy

Summing up

• Majority of work in analytics and data science is in creating useful and predictive data sets

• Data enrichment is key – create long term plans for data assets from many sources

• Machine learning is critical to separate the signal from the noise– Ensure that outcomes of interest are recorded accurately
