StringTable (String Constant Pool) String Fundamentals Strings in Java can be created in two primary ways: String text1 = "java"; // Literal declaration String text2 = new String("code"); // Object instantiation Key characteristics of String class: Declared as final, preventing inheritance Implements Serializable ...

Attention Mechanisms Multi-Head Attention The attention mechanism computes: The scaling factor \(\sqrt{d_k}\) prevents large inner product values that could cause gradient instability. Assuming Q and K elements have mean 0 and variance \(\sigma^2\), the variance of \(QK^T\) grows with \(d_k\). Scaling by \(\sqrt{d_k}\) maintains stable varianc ...
