MaxPooling1D(pool_size=2, strides=None, padding='valid', data_format='channels_last') Max pooling operation for temporal data. Two-dimensional interpolation with scipy. The codes. Guido stated that any solution to better string interpolation would not use locals() or globals() in its implementation. The computation will eventually finish, but this can take several hours (the scaling is probably somewhere between N^2 and N^3). String interpolation uses codes starting with the % symbol as placeholders for inserting variables within the string. OK, what you need is a regression (see: Wolfram, Wiki) or aproximation (see: Wiki).
