This allows us as developers to write the simple generic code, but we still get all of the benefits of ...

"WebbSlices are similar to arrays, but their length is not known at compile time. Instead, a slice is a two-word object; the first word is a pointer to the data, the second word the length of the slice. The word size is the same as usize, determined by the processor architecture, e.g. 64 bits on an x86-64. Slices can be used to borrow a section of ... " - Rust add two vectors

WebbThe ndarray crate supports a number of ways to create arrays -- this recipe creates ndarray::Arrays from std::Vec using from. Then, it sums the arrays element-wise. This recipe contains an example of comparing two floating-point vectors element-wise. Floating-point numbers are often stored inexactly, making exact comparisons difficult. Webb23 mars 2024 · For encoder-decoder attention, we need query vectors for the decoder token embeddings, and key and value vectors for the topmost encoder token embeddings. That’s why we split W into two — a 512x512 and a 512x1024 matrix ( 🤖 ) — and perform two separate projections: one to obtain the key and value vectors from the encoder’s …

This function takes two vectors as arguments and returns a new vector that is the concatenation of the two input vectors. Like so: use std::iter; let a = vec! [1, 2, 3]; let b = vec! [4, 5, 6]; let c = iter::concat (a, b); This will create a new vector c with the elements [1, 2, 3, 4, 5, 6].
