I have access to ArcGIS 10.3. Do I need to get ArcGIS Pro to have access to machine learning? I've read that this is a built-in function in ArcGIS Pro. links: http://www.esri.com/esri-news/arcuser/spring-2018/machine-learning-in-arcgis https://www.youtube.com/watch?v=duZ7jor_YrU
Machine learning is a broad term that includes several algorithms. More and more of these algorithms are available in ArcGIS IF YOU HAVE the spatial analyst or the image analyst extension.
Here are the main novelties. As far as I know they are available from ArcMap (no need of ArcGIS Pro).
Since ArcGIS 9.2, you have a multivariate toolset that include a supervised (Maximum likelihood) and an unsupervised (isoCluster) classifier.
You then have to wait for ArcGIS 10.3 to have support vector machine classifier, and 10.4 for a random forest classifier.
And with ArcGIS 10.6 you have support for some deep learning classifiers (you can convert a model from Tenserflow or microsoft CNTK into a classifier running with ArcGIS.
