GATE CSE 1999 | Question: 2.7, UGCNET-June2014-III: 25
Consider the schema $R=(S,T, U, V)$ and the dependencies $S \rightarrow T, T \rightarrow U, U \rightarrow V$ and $V \rightarrow S$. Let $R = (R1\text{ and } R2)$ be a decomposition such that $R1 \cap R2 \neq \phi$. The decomposition ... but not $\textsf{3NF}$ in $\textsf{3NF}$ but not in $\textsf{2NF}$ in both $\textsf{2NF}$ and $\textsf{3NF}$

UGC NET CSE | November 2017 | Part 3 | Question: 71
Consider a single perceptron with sign activation function. The perceptron is represented by weight vector $\begin{bmatrix} 0.4 & -0.3 & 0.1 \end{bmatrix}^t$ and a bias $\theta=0$. If the input vector to the perceptron is $X=\begin{bmatrix} 0.2 & 0.6 & 0.5 \end{bmatrix}$ then the output of the perceptron is $1$ $0$ $-0.05$ $-1$
