Had the original learning data included only ducks but no rabbits there would have been different results. Had there been different images of ducks the results would have been different. Machine learning is only a complex form of pattern recognition.  The accuracy of what you get out is related to a) The quality of the learning data and b) The quality of the tested data when to try identification.<\/p>\n\n\n\n<p>If your application of machine learning is safety critical and needs 100% accuracy, then machine learning might not be right for you.<\/p>\n\n\n\n<p>Read about <a href=\"https:\/\/www.beaconzone.co.uk\/machinelearning\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"AI Machine Learning with Beacons (opens in a new tab)\">AI Machine Learning with Beacons<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When working with Machine Learning on beacon sensor data or indeed any data, it&#8217;s important to realise AI machine learning isn&#8217;t magic.
