Forecasts with ARIMA Models

In our time series class this morning, I was discussing forecasts with ARIMA Models. Consider some simple stationnary AR(1) simulated time series > n=95 > set.seed(1) > E=rnorm(n) > X=rep(0,n) > phi=.85 > for(t in 2:n) X=phi*X+E > plot(X,type="l") If we fit an AR(1) model, > model=arima(X,order=c(1,0,0), + include.mean = FALSE) > P=predict(model,n.ahead=20) > plot(P$pred) > lines(P$pred+2*P$se,col="red") > lines(P$pred-2*P$se,col="red")...

R based game “2048” with a simple API for ML benchmarking

For a long time I have been on the lookout for a ready-to-use R-based API for testing ML algorithms. My ideal “tool” would be an R-based API for the game “go” (“weiqi” in Chinese and “baduk” in  Korean), but I found none so far. Since writing a rules engine is quite time-consuming, I would not venture developing one until

Install all required R packages on your Shiny server
