Jamie and Greg walk through how it already shows up in everyday resource estimation workflows. From moving averages and detrending through to kriging residuals and convolutional neural networks, this episode focuses on practical application, not theory for theory\u2019s sake. This is Part 1 of a two-part discussion, laying the foundations for how convolution links classical geostatistics with modern machine learning approaches. Key topics and timestamps&amp;nbsp; 00:01 \u2013 Introduction to convolution - geostatistics and machine learning 00:21 \u2013 Separating geological trend from local variability in grade data 02:26 \u2013 Detrending, residuals, and the link to universal kriging 03:15 \u2013 Moving averages as a defensible trend model using convolution 03:41 \u2013 What convolution actually is, explained practically 05:08 \u2013 Choosing window sizes using variograms and cross-validation 05:57 \u2013 Stationarity, variograms, and kriging residuals 07:19 \u2013 How convolution relates to convolutional neural networks (CNNs) 09:22 \u2013 A step-by-step workflow mine geologists can apply with existing data 13:19 \u2013 Summary of key ideas and what\u2019s coming in Part 2 If you enjoyed this episode, please Subscribe for more mining-focused technical discussions across the mine value chain.
