In this twitter thread https://twitter.com/jlowin/status/1061085224862433280, Jeremiah says that the author makes the error of echoing in this article https://heartbeat.fritz.ai/using-a-keras-long-shortterm-memory-lstm-model-to-predict-stock-prices-a08c9f69aa74



"3/6 The echo is the result of a model collapsing in a fit of maximum worthlessness. The model is saying, "My best guess is that tomorrow is pretty much going to be like today," or x_t+1 ≈ x_t. You don't need an AI for that. You barely need a calculator."



Whats wrong with the author model? how should he have done to avoid echo?



Thanks

In R, how to develop a multiplot heatmap.2 figure showing key labels successfully

1 2 I'm trying to develop a multiplot heatmap.2 saved to a pdf. I'm having some success but the axis labels are getting chopped off. Subplot titles are also desirable but again the labels are getting chopped. Here's my reproducible code: library(gridExtra) library(grid) library(gridGraphics) library(gplots) Col = colorRampPalette(c("red","orange","yellow", "white")) grab_grob <- function() grid.echo() grid.grab() par(cex.main=0.1, mar = c(1,1,1,1) ) #data<-read.table("heatmap.input.matrix.data.txt") lmat = rbind(c(2,3),c(4,1),c(4,1)) lwid = c(2.5,4) lhei = c(0.5,4,3) labRowvec <- c(rep(NULL, dim(matrix(runif(1000, 1,10),ncol=50))[1])) labColvec <- c(rep(NULL, dim(matrix(runif(1000, 1,10),ncol=50))[2])) gl <- lapply(1:12, function(i) heatmap.2(matrix(runif(1000, 1,10),ncol=50), dendrogram = "none",offsetRow=-0.5, offsetCol=-1,srtCol=0, density="density", lmat =lmat,lhei = l
