I'm using beamer package to produce slides. I put many figures on a slide by using the subfigure package. The problem is that for captions, the subfigure are labeled "a", "b".. "m", "n" and so on, for subfigures appearing on different slides. How could I reset the subfigure numbering when passing to a new slide?

With beamer's heavily redefined environments and macros to its custom overlay specification, the subfigure counter does not reset at the start of every figure environment. Easiest is to insert
\setcounter{subfigure}{0}% Reset subfigure counter
between the two frames (or before the next frame). If you're willing to have the frame be the designated "master" counter, you could add
\makeatletter
\@addtoreset{subfigure}{framenumber}% subfigure counter resets every frame
\makeatother
at your document start. Alternatively, if you want to tie the subfigure counter to a figure (rather than a frame), you could use
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox
\AtBeginEnvironment{figure}{\setcounter{subfigure}{0}}% Resets subfigure counter at start of figure environment
Based on OP's code, there are a total of 6 images to be shown in a two-columns format (side by side). It seems that the OP wants images in row 2(bin location) and row 3(tables) to show up in the same frame via 2 slides. If the observation is correct, \alt<2>{image1}{image2} should be used instead of \only<1> and \only<2> because <2> does not replace the <1>.
Code
\documentclass{beamer}
\begin{document}
\begin{frame}
\centering
\textbf{Noise effect}
\begin{columns}
\column{0.4\textwidth}
\begin{itemize}
\item $y_1(t)=\cos(2\pi f_1 t)$
\centering
\includegraphics[scale=0.14]{abc}\\
\alt<2>{\includegraphics[scale=0.7]{penguin}}
%\transfade{\includegraphics[scale=0.7]{noiseeffectsine}}
{\includegraphics[scale=0.7]{lion}}
\end{itemize}
\column{0.5\textwidth}
\begin{itemize}
\item $y_2(t)=\text{white noise}$
\centering
\includegraphics[scale=0.14]{abc}\\
\alt<2>{\includegraphics[scale=0.7]{penguin}}
{\includegraphics[scale=0.7]{lion}}
\end{itemize}
\end{columns}
\end{frame}
\end{document}

Instead of doing this for every figure, you could define it once in the preamble:
Alternatively, using the
chngcntrpackage:Though I would expect such a reset per figure as default subfigure behavior, but you did not post your code.
