卷积神经网络(Convolutional Neural Networks, CNN)是一类包含卷积计算且具有深度结构的前馈神经网络(Feedforward Neural Networks),是深度学习(deep learning)的代表算法之一。卷积神经网络具有表征学习(representation learning)能力,能够按其阶层结构对输入信息进行平移不变分类(shift-invariant classification),因此也被称为“...
(1)空间不变性(Spatial Invariance):卷积层的权重共享特性使得网络能够学习到对输入图像中物体位置变化不敏感的特征,这是MLP所不具备的。 (2)多尺度特征学习:通过堆叠多个卷积层和池化层,LeNet能够学习从低级到高级的多尺度特征表示。 (3)自动特征提取:与MLP相比,LeNet不需要手动设计特征提取方法,它能够自动从数据...

这两个操作有两个非常关键的特点:它们是线性的,而且具有平移不变性shift-invariant。平移不变性指我们在图像的每个位置都执行相同的操作。线性指这个操作是线性的,也就是我们用每个像素的邻域的线性组合来代替这个像素。这两个属性使得这个操作非常简单,因为线性操作是最简单的,然后在所有地方都做同样的操作就更简单了...
Multiply the audio by a random amplitude factor to reduce or increase the volume. This technique can help a model become somewhat invariant to the overall gain of the input audio. Warning: This transform can return samples outside the [-1, 1] range, which may lead to clipping or wrap dis...

# The following code templates implement the checks for this invariant: SAVE_TENSOR_STORAGE = CodeTemplate("""\ c10::optional<Storage> ${tensor_name}_storage_saved = ${tensor_name}.has_storage() ? c10::optional<Storage>(${tensor_name}.storage()) : c10::nullopt; ...
Now, let’s say we want to compute the embeddings for the target node 0 at layer K=1, then we aggregate (it is permutation invariant function to its neighbours) all the feature vectors of nodes (including itself) which are at a 1-hop distance from the n...
SIFT(Scale-Invariant Feature Transform)和 HOG(Histogram of Oriented Gradients)是常用的图像特征提取方法,它们在 SVM(Support Vector Machine)图像分类中起着重要作用:SIFT:特征点检测:SIFT 检测图像中的关键点(如角点、边缘等),这些点在尺度和旋转上具有不变性。特征描述符:在检测到的关键点周围,SIFT 计算特征描述...
