What are the best resources to learn about deep learning?

To learn deep learning effectively, focus on three main areas: foundational courses, hands-on frameworks, and community resources. Start with structured courses to build core knowledge. For example, Andrew Ng’s Deep Learning Specialization on Coursera breaks down neural networks, CNNs, and RNNs with clear explanations and coding exercises. Another option is Fast.ai, which offers free, practical courses that prioritize coding over theory, using PyTorch to implement models quickly. Books like Deep Learning for Coders with Fastai and PyTorch by Jeremy Howard and Sylvain Gugger are also useful, blending code examples with conceptual explanations.

Next, experiment with frameworks like TensorFlow or PyTorch. These libraries simplify building and training models. TensorFlow’s documentation includes tutorials for tasks like image classification, while PyTorch’s dynamic computation graphs are helpful for research-oriented projects. Use platforms like Google Colab or Kaggle Notebooks to access free GPU resources, which speed up training. For example, you can test a pre-trained ResNet model on a custom dataset in Colab within minutes. Open-source projects on GitHub, such as the TensorFlow Models repository or PyTorch’s official examples, provide reusable code to study and adapt.

Finally, engage with communities and real-world projects. Kaggle competitions let you apply skills to datasets like MNIST or CIFAR-10, while forums like Stack Overflow or the PyTorch Discussion Board help troubleshoot issues. Follow blogs like Distill.pub for visual explanations of concepts like attention mechanisms. Conferences like NeurIPS or ICML publish papers that showcase current techniques—though focus on implementations in repositories like Papers With Code to see how ideas translate into code. By combining structured learning, practical coding, and community interaction, you’ll build a robust understanding of deep learning.
