所以实际上业务上落地,要不然就是尽量把noise label sample 在training之前或during training的时候做label clean,要不然就是定义一些更复杂的规则来区分开什么样的sample是noise的什么样的sample是hard的,基于graph的一些idea 挺不错的,可以通过sample
In the following graph, you can see the value of the loss function (y-axis) vs. the predicted probability y_i. Here y_i takes values between zero and one. Cross-entropy function depending on prediction value. We can see clearly that the cross-entropy loss function grows exponentially for...
Therefore, based on KRSL, hyper-graph regularization and L 2,1 -norm, we first propose a more robust ELM method named Kernel Risk-Sensitive Loss Based Hyper-graph Regularized Robust Extreme Learning Machine (KRSL-HRELM). In KRSL-HRELM, KRSL is introduced into ELM to enhance its ability to...
Over the last year it has become apparent that advanced machine learning modelsare capable to compete with and even outperform conventional numerical weather prediction models. One of these models is GraphCast, developed by Google, and able to produce deterministic forecasts of hundreds of weather ...
此外,我们还可以看到框架内部用户体验层面的融合。部分参与者指出,TensorFlow以往默认的基于graph的机制无法给予人们直观感受,对初学者而言更不友好。他们解释道:因为PyTorch具有更为直观的命令式模型规范,所以才采用PyTorch。 值得注意的是,由于受到PyTorch带来的冲击,TensorFlow 2.0也采用了PyTorch的接口,使其用户体验与PyTor...
Let's explore cross-entropy functions in detail and discuss their applications in machine learning, particularly for classification issues.
which is often non affordable. Metric learning techniques have allowed a reduction in the required annotated data allowing few-shot learning over deep learning architectures.Aims and Objectives:In this work, we analyze the state-of-the-art loss functions such as triplet loss,contrastive loss, and ...
