Some unimplemented aspects of vw can give meaningful content there ... long term of course, but it may help at least for debug via logs\n\nStephan's Exact steps from latest crash:\n- in AC click tile 8, Titanic Dataset\n- on start page, select \"Predictive Modeling\" + \"survival\" + all other variables for predictors\n- let the flow complete to the end (currently does not fail) you see a confusion matrix visualization\n- go back to algorithm selection decision tile (orange) and on the palette enter values for VW Regression (16 + logistic + 10) and click Apply\n- Red tile will come up after a little more than 2 minutes, saying something like \"action did not come back in time\"\n- At that point the cluster's engine is dead!"}}
