We have composed an overview of activation functions in artificial neural networks here.

We analyze the optimization landscapes of feedforward neural networks here. We show especially that the landscapes of wide networks do not have spurious local minima.

We have discussed the role of statistics in artificial intelligence here.

We have established risk bounds for robust deep learning here.

We have put a new paper about layer sparsity in neural networks on arXiv.

We have derived statistical guarantees for deep learning here. Well done, Mahsa and Fang! ⚡⚡⚡

We have established a new strategy for calibrating the graphical lasso here. Great work, Mike! 🍷

We have uploaded a new paper on the lasso’s effective noise and on consequences for calibration and inference here. Thanks to Michael for the great collaboration!

We have uploaded a paper on tuning-free ridge regression here. Well done, Shih-Ting and Fang!
