  2. Normalization (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(machine...

    Adaptive instance normalization (AdaIN) is a variant of instance normalization, designed specifically for neural style transfer with CNNs, rather than just CNNs in general. [ 27 ] In the AdaIN method of style transfer, we take a CNN and two input images, one for content and one for style .

  3. Batch normalization - Wikipedia

    en.wikipedia.org/wiki/Batch_normalization

    In a neural network, batch normalization is achieved through a normalization step that fixes the means and variances of each layer's inputs. Ideally, the normalization would be conducted over the entire training set, but to use this step jointly with stochastic optimization methods, it is impractical to use the global information.

  4. Instance selection - Wikipedia

    en.wikipedia.org/wiki/Instance_selection

    Instance selection (or dataset reduction, or dataset condensation) is an important data pre-processing step that can be applied in many machine learning (or data mining) tasks. [1] Approaches for instance selection can be applied for reducing the original dataset to a manageable volume, leading to a reduction of the computational resources that ...

  5. Normalisation by evaluation - Wikipedia

    en.wikipedia.org/wiki/Normalisation_by_evaluation

    And if the datatype of normal forms is typed, the type of reify (and therefore of nbe) then makes it clear that normalization is type preserving. [ 9 ] Normalization by evaluation also scales to the simply typed lambda calculus with sums ( + ), [ 7 ] using the delimited control operators shift and reset .

  6. Feature scaling - Wikipedia

    en.wikipedia.org/wiki/Feature_scaling

    Without normalization, the clusters were arranged along the x-axis, since it is the axis with most of variation. After normalization, the clusters are recovered as expected. In machine learning, we can handle various types of data, e.g. audio signals and pixel values for image data, and this data can include multiple dimensions. Feature ...

  7. AlexNet - Wikipedia

    en.wikipedia.org/wiki/AlexNet

    This increases the size of the training set 2048-fold. Randomly shifting the RGB value of each image along the three principal directions of the RGB values of its pixels. It used local response normalization, and dropout regularization with drop probability 0.5. All weights were initialized as gaussians with 0 mean and 0.01 standard deviation.

  8. Data cleansing - Wikipedia

    en.wikipedia.org/wiki/Data_cleansing

    Data cleansing may also involve harmonization (or normalization) of data, which is the process of bringing together data of "varying file formats, naming conventions, and columns", [2] and transforming it into one cohesive data set; a simple example is the expansion of abbreviations ("st, rd, etc." to "street, road, etcetera").

  9. Softmax function - Wikipedia

    en.wikipedia.org/wiki/Softmax_function

    The normalization ensures that the sum of the components of the output vector () is 1. The term "softmax" derives from the amplifying effects of the exponential on any maxima in the input vector. The term "softmax" derives from the amplifying effects of the exponential on any maxima in the input vector.
