What are the responsibilities of a “linear algebra library”? • Layer -1: Fundamentals • Multidimensional arrays & iteration • Layer 0: Performance primitives • Vector: dot, norm, vector sum, plane update • Layer 1: Low-level math problems • Linear systems 𝐴𝑥 = 𝑏 (& determinants, etc.) • Least-squares problems min 𝑥 𝐴𝑥 − 𝑏 2 • Eigenvalue & singular value problems 𝐴𝑥 = 𝜆𝑥 • Layer 2: Higher-level What are the responsibilities of a “linear algebra library”? • Layer -1: Fundamentals • Multidimensional arrays & iteration • Layer 0: Performance primitives • Vector: dot, norm, vector sum, plane

the weights are all different14. Figure 3 shows a model of a perceptron. Note that there is just 1 layer of neurons, the darker nodes, but those neurons are the McCulloch Pitt neurons mentioned previously (1) 1 input x output y bias 0 1 2 3 ... i 1 2 3 ... j Figure 2: A model of a single layer Perceptron. Note that only the darker nodes are actual neurons, the lighter ones are there to show perceptron. 4.2.2 The Multilayer Perceptron To make the perceptron more useful, we now have another layer. The problem with doing this is that the algorithm needed to train it is rather more compli- cated

Introduction ...... Struts on top, but you could also choose to just use the Hibernate integration or the JDBC abstraction layer. Spring is non-intrusive, meaning dependencies on the framework are generally none or absolutely minimal creation of contexts by, for example, a servlet container. The DAO package provides a JDBC-abstraction layer that removes the need to do tedious JDBC coding and parsing of database-vendor specific error codes
