Compression is prediction
• Modern data compression uses transforms, models, and entropy coders like arithmetic coding to shrink data.
• Arithmetic coding compresses entire datasets into a single number based on symbol probabilities.
• Higher symbol probabilities allow compression to fewer bits per symbol, measured by entropy.
• Context-aware models (order-N) vastly improve compression by predicting next symbols more accurately.
• Large language models (LLMs) excel at prediction, enabling superior compression but with high computational cost.#DataCompression #LanguageModeling #EntropyCoding
