 ## Overview
 
 The following fusion patterns are subgraphs that the oneDNN Graph API recognizes
-as candidate for fusion. The patterns are described using oneDNN Graph
+as candidates for fusion. The patterns are described using oneDNN Graph
 operation (op) names with the following convention.
 
 @note oneDNN Graph performs limited input validation to minimize the performance
 overheads. The application is responsible for sanitizing inputs passed to the
-library. For large u8 or s8 inputs may lead to accumulator overflow, you can use
