What if we try just overwriting overlapping data for the same dates first, since there could be some users (myself included) who only ran the two datasets in parallel for a short time. One simple way would be to set a cut-off date. Of course a huge CAVEAT in red text's gotta be ...
Another regularization approach, OHT [37], applies the so-called extended Hough transform on a list of ordered boundary points that enable to detect arbitrary building directions and extract different boundary segments. The comparison metrics considered are the building corners geometric accuracy (RMSE)...

To demonstrate the new functionality, we work with two datasets: leads and web marketing metrics. These datasets can be used to build a model that predicts if a lead will convert into a sale given marketing activities and metrics captured for that...
