EigenPro [1-3] is a GPU-enabled fast and scalable solver for training kernel machines. It applies a projected stochastic gradient method with dual preconditioning to enable major speed-ups. It is currently based on a PyTorch backend.
- Fast: EigenPro is the fastest kernel method at large scale.
- Plug-and-play: Our method learns a quality model with little hyper-parameter tuning in most cases.
- Scalable: The training time of one epoch is nearly linear in both model size and data size. This is the first kernel method that achieves such scalability without any compromise on testing performance.
- Support for multi-GPU and model-parallelism: We are adding support for multiple GPUs and model-parallelism.

In the experiments described below, P denotes the number of centers (model size), essentially representing the model size, while 'd' signifies the ambient dimension. For all experiments, a Laplacian kernel with a bandwidth of 20.0 was employed.
We used extracted features from the pretrained 'mobilenet-2' network available in the timm library. The benchmarks processed the full 5 million samples of CIFAR5M with d = 1280 for one epoch for two versions of EigenPro and FALKON [4-6]. All of these experiments were run on a single A100 GPU. The maximum RAM we had access to was 1.2TB, which was not sufficient for FALKON with 1M centers.
We used 10 million samples with d = 1024 for one epoch for two versions of EigenPro and FALKON. All of these experiments were run on a single V100 GPU. The maximum RAM available for this experiment was 300GB, which was not sufficient for FALKON with more than 128K centers. The features are extracted using an acoustic model (a VGG+BLSTM architecture in [7]) to align the length of audio and text.
