Multi-scale Patch Aggregation (MPA) for Simultaneous ...

www.cse.cuhk.edu.hk

Recently, simultaneous detection and segmentation (S-DS) [14] becomes a promising direction to generate pixel-level labels for every object instance, naturally leading to the next-generation object recognition [24] goal. Accurate and efficient SDS can be used in a lot of disciplines as a fundamental tool, where both pixel-wise label and object

Homework # 5 Solution

www.cse.cuhk.edu.hk

Solution: Let s be the initial price of the stock. Denote X the number of increase periods among the 1000 time periods. Then the price at the end is suXd1000−X In order for thye price to be at least 1.3s, we need d1000(u d)X > 1.3 ⇒ X > log(1.3)−1000logd log(u/d) ≈ 469.2 That is, we need at least 470 increase periods.
