  Lamp provides utilities to build state of the art machine learning applications

  Overview

  Notable types and packages:

  • lamp.STen is a memory managed wrapper around aten.ATen, an off the heap, native n-dimensionl array backed by libtorch.
  • lamp.autograd implements reverse mode automatic differentiation.
  • lamp.nn contains neural network building blocks, see e.g. lamp.nn.Linear.
  • lamp.data.IOLoops implements a training loop and other data related abstractions.
  • lamp.knn implements k-nearest neighbor search on the CPU and GPU
  • lamp.umap.Umap implements the UMAP dimension reduction algorithm
  • lamp.onnx implements serialization of computation graphs into ONNX format
  • lamp.io contains CSV and NPY readers

  How to get data into lamp

  Use one of the file readers in lamp.io or one of the factories in lamp.STen$.

  How to define a custom neural network layer

  See the documentation on lamp.nn.GenericModule

  How to compose neural network layers

•  package nn

  Provides building blocks for neural networks

  Provides building blocks for neural networks

  Notable types:

  • nn.GenericModule is an abstraction on parametric functions
  • nn.Optimizer is an abstraction of gradient based optimizers
  • nn.LossFunction is an abstraction of loss functions, see the companion object for the implemented losses
  • nn.SupervisedModel combines a module with a loss

  Optimizers:

  • nn.AdamW
  • nn.SGDW
  • nn.RAdam
  • nn.Yogi

  Modules facilitating composing other modules:

  • nn.Sequential composes a homogenous list of modules (analogous to List)
  • nn.sequence composes a heterogeneous list of modules (analogous to tuples)
  • nn.EitherModule composes two modules in a scala.Either

  Examples of neural network building blocks, layers etc:

  • nn.Linear implements W X + b with parameters W and b and input X
  • nn.BatchNorm, nn.LayerNorm implement batch and layer normalization
  • nn.MLP is a factory of a multilayer perceptron architecture
