Before revision:  This gain can be achieved at little extra cost to practitioners since it uses data currently available to them . Consequently, our machine learning algorithms can improve the detection of long-term income support recipients accruing a welfare cost nearly AUD 1 billion higher than individuals identified in the current system .
After revision:  This gain can be achieved at little extra cost to practitioners since the algorithms use administrative data currently available to them . Consequently, our machine learning algorithms can improve the detection of long-term income support recipients accruing a welfare cost nearly AUD 1 billion higher than individuals identified in the current system .
