I have a script that uses keras.datasets.mnist. It reshapes into a 2D array and a 1D vector of labels: sklearn.exceptions.DataConversionWarning: A column-vector y was passed when a 1d array was ...

Figure 1: A 1D array of degenerate cavities for simulating a 2D rectangular lattice in a magnetic field. (a) The optical design for simulating .

In our prior study of an L-bit priority encoder (PE), a so-called one-directional-array to two-directional-array conversion method is deployed to turn an L-bit input data into an M × N-bit matrix.

The Matrix2 Accelerator is a high-performance multi-core vector processor for high-density computing that supports fused multiply-add instructions. We propose an efficient large-scale 1D FFT ...

There's nothing wrong with your code; when you have a discrete outcome, the residuals end up being an array even though you started with a vector, and for whatever reason RandomForestRegressor (your ...
