Information Extraction Vector Semantics Dense Vectors Dan Jurafsky Sparse versus dense vectors • PPMI vectors are • long (length |V|= 20,000 to 50,000) • sparse (most elements are zero) • Alternative: learn vectors which are • short (length 200-1000) • dense (most elements are non-zero) 2 Dan Jurafsky Sparse versus dense vectors • Why dense

Introduction to Computer Architecture Function Calls For this program, you will write a series of tests for a linear search function. The search function, some data, and a basic test suite are provided for you, so you will only need to create the code that uses the existing test suite functions to ensure that the
