Revisiting Batch Normalization: Why It Worked and Why We Moved On
Batch normalization was a breakthrough that made deep networks trainable, but its practical cost eventually outweighed its theoretical elegance. The technique worked because it stabilized internal covariate shift, smoothing the optimization landscape and allowing higher learning rates. Yet researchers moved on as its reliance on batch statistics became inconvenient for smaller batches, recurrent architectures, and inference. It's worth revisiting why this old friend succeeded before we dismissed it. For a deeper look at how research priorities shift, see "From Research Fatigue to Fresh Ideas."
Teaching Foundation Models New Skills Without Breaking Them
Teaching foundation models new skills without breaking what they already know is one of the hardest challenges in AI. A new reinforcement learning approach, on-policy self-distillation, might finally offer a path forward. It's a promising idea, one that could reshape how we think about post-training. For a deeper look at how models are learning to build their own tools, see our coverage of Recursive's Flint.
Discover how AI transforms stereo tracks into immersive spatial audio experiences.
For six months, a developer wrestled with a stubborn problem: most music lacks a quality spatial mix. The result is Stereo2Spatial, an open-source model that converts stereo tracks into spatialized binaural audio. The journey wasn't smooth, though. Latent-space attempts hit quality ceilings, and raw waveform training kept collapsing into instability. A clever fix from the WavFlow paper finally stabilized things.
