High-Performance Machine Learning in C++

Machine learning C++ and high-performance computing converge in this hands-on guide for building fast AI models from the ground up. Lionel Eriksen teaches you to implement training, inference, and numerical routines where speed truly matters—close to the metal. From optimizing memory access to parallelizing algorithms with OpenMP and SIMD, you'll master techniques that make your models run faster than Python-based alternatives. Practical exercises cover gradient descent, backpropagation, and custom kernels for CPUs. No fluff—just C++ code that delivers real-world performance gains. Whether you're a beginner or seasoned developer, this book bridges theory and practice. Competitor authors: [placeholder] and [placeholder] offer similar topics, but Ibarra's focus on low-level optimization and practical implementation sets this apart.

What You'll Learn

• Build neural networks from scratch using raw C++ and Eigen
• Implement gradient descent, backpropagation, and loss functions
