I want to put my figures and plots at the top of the page. This with figure works

\begin{figure}[h]

\begin{minipage}[b]{1.0\linewidth}
  \centering
  \centerline{\includegraphics[width=8.5cm]{results}}
%  \vspace{2.0cm}
  \centerline{(a) Result 1}\medskip
\end{minipage}
%
\begin{minipage}[b]{.48\linewidth}
  \centering
  \centerline{\includegraphics[width=4.0cm]{results}}
%  \vspace{1.5cm}
  \centerline{(b) Results 3}\medskip
\end{minipage}
\hfill
\begin{minipage}[b]{0.48\linewidth}
  \centering
  \centerline{\includegraphics[width=4.0cm]{results}}
%  \vspace{1.5cm}
  \centerline{(c) Result 4}\medskip
\end{minipage}
%
\caption{Example of placing a figure with experimental results.}
\label{fig:res}

\end{figure}

    BING &  \textbf{0.01} \\

Best Answer

The equivalent environment of figure for tables is the table environment. Wrap your tabu in a table environment:

\begin{table}[t]
  \begin{tabu} to 0.8\columnwidth { | X[c] | X[c] | }
  ...
  \end{tabu}
  \caption{Some caption.}
\end{table}
