WebExample 2: x^2 (1-x) Example 3: 1/2*abs (x)x^2. Select an option to approximate: Legendre, Chebyshev, Cosine or Sine. Drag the slider n to approximate. Remark: Notice that the approximation is INCORRECT since the first three coefficients are zero by default in the simulation. Calculate the CORRECT coefficients, rounded to two decimals places ... Webfor Polynomial Approximation Itai Shapira Harvard University Abstract We analyze the number of neurons that a ReLU neural network needs to ap-proximate multivariate monomials. We establish an exponential lower bound for the complexity of any shallow network that approximates the product function x → Qd i=1xi onageneralcompactdomain.
