Webtorch.nn.functional.huber_loss — PyTorch 2.0 documentation torch.nn.functional.huber_loss torch.nn.functional.huber_loss(input, target, reduction='mean', delta=1.0) [source] Function that uses a squared term if the absolute element-wise error falls below delta and a delta-scaled L1 term otherwise. See … Web27 jun. 2024 · 与平方误差损失相比较，Huber Loss对数据中的噪声（异常值）不敏感。在0处也是可微的。Huber Loss 基本上算是绝对误差，当误差很小的时候就变成了二次方值（下面公式可以看出）。误差有多小时，Huber Loss 会变成二次方值 取决于超参数，这个超参数是需要手动 ... heather menzies wikipedia

Web8 feb. 2024 · Using the loss function is as simple as specifying the loss function in the loss argument of model.compile (). model = tf.keras.Sequential( [ tf.keras.layers.Dense(units=1, input_shape=[1,]) ]) model.compile(optimizer='sgd', loss=my_huber_loss) model.fit(xs, ys, epochs=500, verbose=0) Web8 feb. 2024 · The definition of Huber Loss is like this: Lδ(a) = { 1 2(y −f(x))2 δ( y− f(x) − 1 2δ) for a ≤ δ, otherwise [ ] def my_huber_loss(y_true, y_pred): threshold = 1. error = y_true - y_pred... In statistics, the Huber loss is a loss function used in robust regression, that is less sensitive to outliers in data than the squared error loss. A variant for classification is also sometimes used. heather menzies-urich photos
