Deep Learning Engineer Interview Questions and Answers for Freshers

The task is to color a graph with two colors in a way that no two adjacent vertices share the same color.

• Check if the graph can be colored using two colors without any adjacent vertices sharing the same color.

• Use graph coloring algorithms like Greedy Coloring or Backtracking to solve the problem.

• Consider connected components in the graph while coloring.

• If a vertex has an odd cycle, it is not possible to color the graph with two colors.

Implement a wildcard pattern matching algorithm to determine if a given wildcard pattern matches a text string completely.

• Create a recursive function to match the pattern with the text character by character.

• Handle cases for '?' and '*' characters in the pattern.

• Use dynamic programming to optimize the solution.

• Check for edge cases like empty pattern or text.

• Iterate through the pattern and text to determine if they match completely.

The loss function of YOLO is a combination of localization loss, confidence loss, and classification loss.

• YOLO uses a sum-squared error loss function to calculate the localization loss, which penalizes the difference between the predicted bounding box and the ground truth bounding box.

• The confidence loss penalizes the model for incorrect objectness predictions and no object predictions in grid cells.

• The classification loss is calculated using a softmax function to predict the...read more
