@jjjzy Thanks for this information. This sounds like a workaround for now.

Yes. I was aware of this algorithm. However, we need to think about whether this can be quickly included due to dependency. Would like to keep requirements file slim. In...

this is a good point. The difficulty is exactly as you mentioned...unsupervised outlier detection is challenging and we do not know when and whether a certain algorithm could work for...

This is correct. No online learning or streaming setting is considered for now.

as suggested, please update combo library to 0.1.2 pip install combo --upgrade https://github.com/yzhao062/pyod/issues/276

this is a nice direction but feel like out of the scope of PyOD which only focuses on outlier detection. Happy to see if you would like to add some...

Agreed that a model save functionality should be added. Marked as a todo task. I am not sure whether pickle will work or not (hopefully yes), and I will also...

@epicsol-inc sorry for the late response. AE in pyod is written with keras, and saving the model can be tricky. To my understanding, keras models may not be pickable (https://github.com/keras-team/keras/issues/10528)......
