From the above paper, a Mixed Convolution is a group of convolutions with varying filter sizes. The paper suggests that [3x3, 5x5, 7x7] can be used safely without any loss in performance (and possible increase in performance), while a 9x9 or 11x11 may degrade performance if used without proper architecture search.

From Master branch:
pip install git+https://github.com/titu1994/keras_mixnets.git OR git clone https://github.com/titu1994/keras_mixnets.git cd keras_mixnets pip install .
Due to the use of Model Subclassing, the keras model built *cannot be deserialized using
load_model. You must build the model each time. tf.keras supports writing Layers which have additional Layers within them, but as Keras itself does not support it yet, these models cannot be deserialized using
from keras_mixnets import MixNetSmall # Medium and Large can also be used model = MixNetSmall((224, 224, 3), include_top=True)
Weights for these models have not been ported yet from Tensorflow.
