• Title: Deep Transfer Learning with Ridge Regression
• Authors: Shuai Tang, Virginia R. de Sa
• Abstract summary: Deep models trained with massive amounts of data demonstrate promising generalisation ability on unseen data from relevant domains. We address this issue by leveraging the low-rank property of learnt feature vectors produced from deep neural networks (DNNs) with the closed-form solution provided in kernel ridge regression (KRR) Our method is successful on supervised and semi-supervised transfer learning tasks.

• Abstract: The large amount of online data and vast array of computing resources enable current researchers in both industry and academia to employ the power of deep learning with neural networks. While deep models trained with massive amounts of data demonstrate promising generalisation ability on unseen data from relevant domains, the computational cost of finetuning gradually becomes a bottleneck in transfering the learning to new domains. We address this issue by leveraging the low-rank property of learnt feature vectors produced from deep neural networks (DNNs) with the closed-form solution provided in kernel ridge regression (KRR). This frees transfer learning from finetuning and replaces it with an ensemble of linear systems with many fewer hyperparameters. Our method is successful on supervised and semi-supervised transfer learning tasks.

  A different idea has been recently proposed, named Friendly Training, which consists in altering the input data by adding an automatically estimated perturbation. We revisit and extend this idea inspired by the effectiveness of neural generators in the context of Adversarial Machine Learning. We propose an auxiliary multi-layer network that is responsible of altering the input data to make them easier to be handled by the classifier.

• On The Transferability of Deep-Q Networks [6.822707222147354]
  Transfer Learning is an efficient machine learning paradigm that allows overcoming some of the hurdles that characterize the successful training of deep neural networks. While exploiting TL is a well established and successful training practice in Supervised Learning (SL), its applicability in Deep Reinforcement Learning (DRL) is rarer. In this paper, we study the level of transferability of three different variants of Deep-Q Networks on popular DRL benchmarks and on a set of novel, carefully designed control tasks.

  We propose a transfer learning approach to improve predictive power in noisy data systems with large variable confidence datasets. We propose a deep neural network method called Filtered Transfer Learning (FTL) that defines multiple tiers of data confidence as separate tasks. We demonstrate that using FTL to learn stepwise, across the label confidence distribution, results in higher performance compared to deep neural network models trained on a single confidence range.

• On transfer learning of neural networks using bi-fidelity data for uncertainty propagation [0.0]
  We explore the application of transfer learning techniques using training data generated from both high- and low-fidelity models. In the former approach, a neural network model mapping the inputs to the outputs of interest is trained based on the low-fidelity data. The high-fidelity data is then used to adapt the parameters of the upper layer(s) of the low-fidelity network, or train a simpler neural network to map the output of the low-fidelity network to that of the high-fidelity model.

Backpropagation, the workhorse for training these networks, is an inherently sequential process that is difficult to parallelize. We propose a neuro-biologically-plausible alternative to backprop that can be used to train deep networks.
