-*BatchNormInference*  normalizes the output in each hidden layer.
+Let `x` be a *d*-dimensional input, \f$x=(x_{1}\dotsc x_{d})\f$. Since normalization is applied to each activation \f$E[x^{(k)}]\f$, you can focus on a particular activation and omit k.
+
+For a particular activation, consider a mini-batch \f$\mathcal{B}\f$ of m values. *BatchNormInference* performs Batch Normalization algorithm as follows:

+    This transformation converts the operation MXFFT into OpenVINO DFT (if the attribute 'is_inverse' is False),
+    or into OpenVINO IDFT (otherwise).
+
+    According to https://mxnet.apache.org/versions/1.0.0/api/python/symbol/contrib.html#mxnet.symbol.contrib.fft,
+    MxNet operation FFT accept 2 input data shapes: [N, d] or [N_1, N_2, N_3, d], data can only be real numbers.
+    The output data has shape: [N, 2*d] or [N_1, N_2, N_3, 2*d]. The format is: [real0, imag0, real1, imag1, ...].
+
+    Next, MxNet operation IFFT accept 2 input data shapes: [N, d] or [N_1, N_2, N_3, d]. Data is in format:
+    [real0, imag0, real1, imag1, ...]. Last dimension must be an even number. The output data has shape: [N, d/2] or
+    [N_1, N_2, N_3, d/2]. It is only the real part of the result.
+
+    But OpenVINO DFT and IDFT operations uses complex input data represented as real tensors of the shape
+    [N_1, ..., N_r, 2]. Also, the result of OpenVINO DFT and IDFT operations is always complex but represented as
+    a real tensor of the shape [M_1, ..., M_r, 2]. If OpenVINO DFT or IDFT have no input signal_size, the output shape
+    and the input shape are the same.
+
+    Hence, to convert MxNet FFT to OpenVINO DFT, we need
+    1) to convert input data from the shape [N, d] or [N_1, N_2, N_3, d] to shape [N, d, 1] or [N_1, N_2, N_3, d, 1]
+       respectively;
+    2) to pad converted data using pads_begin = [0, 0, 0] and pads_end = [0, 0, 1] for MxNet FFT input shape [N, d], or
+       using pads_begin [0, 0, 0, 0, 0] and pads_end = [0, 0, 0, 0, 1] for MxNet FFT input shape [N_1, N_2, N_3, d],
+       with mode=constant;
+    3) to put padded data into DFT input 0, using (-1) in 'axes' input;
+    4) to reshape calculated DFT output to the shape [N, 2 * d] for for MxNet FFT input shape [N, d], or to the shape
+       [N_1, N_2, N_3, 2 * d]
+
+    Finally, to convert MxNet IFFT to OpenVINO IDFT, we need
+    1) to reshape input data from the shape [N, d] or [N_1, N_2, N_3, d] to shape [N, d // 2, 2] or
+       [N_1, N_2, N_3, d // 2, 2] respectively;
+    2) to put reshaped input data to the input 0 of IDFT, using (-1) in 'axes' input;
+    3) to get real parts using Split + Squeeze.
