The output sequence of the mixture source is chosen from the source $i \\in \\{1,\\ldots ,K\\}$ with a $d_i$-dimensional parameter vector at random according to probability vector $\\mathbf{w} = (w_1,\\ldots,w_K)$. The average minimax redundancy of the universal compression of a new random sequence of length $n$ is derived when the encoder and the decoder have a common side information of $T$ sequences generated independently by the mixture source.
