The learning method achieves a better fault-tolerant ability, compared with weight-decay-based regularizers. In , a regularization-based objective function for training a functional link network to tolerate multiplicative weight noise is defined, and a simple learning algorithm is derived. The function link network is somewhat similar to the ...

In this paper, we investigate a group sparse optimization problem via l p,q regularization in three aspects: theory, algorithm and application. In the theoretical aspect, by introducing a notion of group restricted eigenvalue condition, we establish an oracle property and a global recovery bound of order O(λ2/2-q) for any point in a level set of the l p,q regularization problem, and by virtue ... 32 bit microprocessor list

Notes. Higher momentum also results in larger update steps. To counter that, you can optionally scale your learning rate by 1 - momentum.. The classic formulation of Nesterov momentum (or Nesterov accelerated gradient) requires the gradient to be evaluated at the predicted next position in parameter space. The non-convexity of the solution space means that @generic_user likely wasn't finding the optimal weight at each regularization step, but was probably getting closer at each initialization. This allows for the loss to decrease with each re-initialization.

Jan 09, 2019 · This repository contains the code for the paper Decoupled Weight Decay Regularization (old title: Fixing Weight Decay Regularization in Adam) by Ilya Loshchilov and Frank Hutter, ICLR 2019 arXiv. The code represents a tiny modification of the source code provided for the Shake-Shake regularization by Xavier Gastaldi arXiv. Since the usage of both is very similar, the introduction and description of the original Shake-Shake code is given below. Bibliographic content of ICLR 2019. Robert Geirhos, Patricia Rubisch, Claudio Michaelis, Matthias Bethge, Felix A. Wichmann, Wieland Brendel: ImageNet-trained CNNs are biased towards texture; increasing shape bias improves accuracy and robustness. Historically, stochastic gradient descent methods inherited this way of implementing the weight decay regularization. The currently most common way (e.g., in popular libraries such as TensorFlow, Keras, PyTorch, Torch, and Lasagne) to introduce the weight decay regularization is to use the L 2 regularization term as in Eq.

The non-convexity of the solution space means that @generic_user likely wasn't finding the optimal weight at each regularization step, but was probably getting closer at each initialization. This allows for the loss to decrease with each re-initialization. Deep Reinforcement Learning (Deep RL) has been receiving increasingly more attention thanks to its encouraging performance on a variety of control tasks. Yet ...

We propose NovoGrad, a first-order stochastic gradient method with layer-wise gradient normalization via second moment estimators and with decoupled weight decay for a better regularization.

This class alone is not an optimizer but rather extends existing optimizers with decoupled weight decay. We explicitly define the two examples used in the above paper (SGDW and AdamW), but in general this can extend any OptimizerX by using extend_with_decoupled_weight_decay( OptimizerX, weight_decay=weight_decay). In order for it to work, it ...
