ImageNet Classification with Deep Convolutional Neural Networks
Summary
AlexNet introduced a deep convolutional network with ReLU activations, dropout regularization, and multi‑GPU training, achieving 15.3% top‑5 error on ImageNet 2012, far surpassing prior results. The paper demonstrated that large‑scale CNNs are feasible and set the foundation for modern deep vision.
- ReLU non‑linearity trains several times faster than tanh, enabling deep networks on large data.
- Dropout applied to fully‑connected layers dramatically reduces overfitting.
- Model parallelism across two GPUs with limited inter‑GPU communication improves accuracy and training speed.
- Architecture of 5 conv + 3 FC layers (~60 M parameters) achieved 15.3% top‑5 error, a record at the time.
Deep‑learning engineers and researchers building large‑scale vision models should know the techniques that made modern CNNs practical.
