WiredBrief are delighted to bring to you an exciting presentation from the second edition of AI Waves, which looks at Nextbanks AI driven FinTech credit scoring solution
About this event
Exciting developments in Artificial intelligence (AI) are explored by AI Waves during their second instalment: āForget scorecards and turn your credit scoring into a money-making machineā, which looks at AIs application within FinTech.
This keynote focuses on NextBanks highly sophisticated credit scoring solution which helps solve traditional problems experienced in banking, relating to credit score transparency and maintenance. The use of AI within credit scoring has allowed large amounts of data to be used to determine specific actions / factors that affect credit user scores. These factors are then used to automatically create credit scoring models, which enable more proactive decisions to be taken by both banks and private users alike.
