 Mar 13 answered If $\lim_{x\to 0}\frac{\cos^2x-\cos x-e^x\cos x+e^x-\frac{x^3}{2}}{x^n}$ is a non zero finite number number, find $n$ where $n\in\mathbb{N}$ Feb 22 awarded Excavator Feb 22 comment Why does a radial basis function kernel imply an infinite dimension map? stats.stackexchange.com/a/58607/10823 Feb 22 revised Why does a radial basis function kernel imply an infinite dimension map? Fixed latex, fixed incorrect notation usage and added missing details Feb 2 comment Show that $\frac{1}{1+k}=\frac{\frac{1}{k}}{1+\frac{1}{k}}\leq \ln(1+\frac{1}{k})\leq\frac{1}{k}$ @JellyBelly math.stackexchange.com/questions/504663/… Feb 2 revised Show that $\frac{1}{1+k}=\frac{\frac{1}{k}}{1+\frac{1}{k}}\leq \ln(1+\frac{1}{k})\leq\frac{1}{k}$ added 36 characters in body Feb 1 answered Show that $\frac{1}{1+k}=\frac{\frac{1}{k}}{1+\frac{1}{k}}\leq \ln(1+\frac{1}{k})\leq\frac{1}{k}$ Jan 27 comment Derivative of trace of matrix product cal.cs.illinois.edu/~johannes/research/matrix%20calculus.pdf Jan 23 answered Finding $\sum_{k=1}^{\infty}k^2 \frac{2^{k-1}}{3^k}$ Jan 20 comment Solving SVM classifier with two weight vectors @user2204324 Updated based on your recent edits. Jan 20 revised Solving SVM classifier with two weight vectors added 597 characters in body Jan 20 comment Solving SVM classifier with two weight vectors @user2204324 just updated the constraints as well. Jan 20 revised Solving SVM classifier with two weight vectors added 243 characters in body Jan 20 answered Solving SVM classifier with two weight vectors Jan 13 comment Prove that $\int_{2}^{\infty} \frac{dx}{x^{1-\epsilon}\cdot \ln(x)^{\beta}}$ diverges for every $\beta$. Put $\ln x = y$. Should make your analysis easier. Jan 13 comment Mutual Information Always Non-negative @becko The same arguments hold, you just have to replace the summations by integrals. Jan 11 answered How to prove $\cos \theta + \sin \theta =\sqrt{2} \cos\theta$. Dec 16 awarded Tenacious Nov 21 comment Prove that Pb(x) = x / $||$x$||$ if $||$x$||$ $\gt$ 1 or x if $||$x$||$ $\leq$ 1. Hint: Think of 2D space. Draw the norm ball, which is essentially a circle at the center in 2D. Take any point x in the plane. If you draw a line from the center to that point x, then this line will intersect with the exterior of the norm ball, what is that point? Nov 8 awarded Nice Answer
