Pt1 <- c(my_data[[5]], my_data[[6]]) This code uses the double brackets to select the 5th and 6th columns of the data frame as separate vectors, and then concatenates them into a single vector using the c() function. Now, when you run typeof(Pt1), you should get: [1] "...

You either duplicate the data from the left part or from the right part at a time so overall input to the model is different each time. As for one-hot encoding of labels, just the final shape has to match i.e. 24-dimensional vector. Now if it's a multiclass classification problem, ...

To construct a single piece of delimited text from a cell array of character vectors or a string array, use thestrjoinfunction. Algorithms When concatenating an empty array to a nonempty array,horzcatomits the empty array in the output. For example,horzcat([1 2],[])returns the row vector[...
This is short-hand for ``np.r_['-1,2,0', index expression]``, which is useful because of its common occurrence. In particular, arrays will be stacked along their last axis after being upgraded to at least 2-D with 1's post-pended to the shape (column vectors made out of 1-D ...
