Resource Title : High-Resolution Representations for Labeling Pixels and Regions (HRNetV2) Paper : https://arxiv.org/pdf/1904.04514.pdf Motivation & Introduction Vision Task에서 High-Resolution representation learning은 중요한 역할을 한다. 하지만, 기존의 연구들의 대부분은 low-resolution 혹은 medium-resolution으로부터 High-Resolution을 복원하거나 dilated convolution을 통해서 medium-resolution을 계산하는게 전부이다. 비록 이렇게 resolution을 줄여야 receptiv..

정형 데이터에서 범주형 변수를 처리하는 방법은 되게 까다롭습니다. 이번 포스팅에서는 제가 알고 있는 범주형 변수들에 대해서 설명하고 어떤 의미를 가지고있는지에 대해 작성해보도록 하겠습니다. 먼저 범주형 변수란 일종의 카테고리를 가지는 변수를 의미합니다. 예를들어 식물의 종도 일종의 카테고리가 되고 음식점의 종류 등 어떠한 집단을 의미하는 변수들을 의미합니다. 이러한 변수들은 컴퓨터가 인식할 수 없기에 인식할 수 있도록 인코딩을 해주는 작업이 필요합니다. 대표적으로 많이 알려진 인코딩 기법으로는 One-Hot Encoding, Label Encoding, Frequency Encoding, Target Encoding 등이 있습니다. 먼저, One-Hot Encoding은 일종의 변수를 1과 0으로 나누는..

Input Format The STATION table is described as follows: where LAT_N is the northern latitude and LONG_W is the western longitude. Q1. Query the following two values from the STATION table: The sum of all values inLAT_Nrounded to a scale ofdecimal places. The sum of all values inLONG_Wrounded to a scale ofdecimal places. Output Format Your results must be in the form: lat lon where lat is the sum..

We define an employee's total earnings to be their monthly salary x months worked, and themaximum total earningsto be the maximum total earnings for any employee in the Employee table. Write a query to find the maximum total earnings for all employees as well as the total number of employees who have maximum total earnings. Then print these values as 2space-separated integers. Input Format T..

Samantha was tasked with calculating the average monthly salaries for all employees in the EMPLOYEES table, but did not realize her keyboard's 0 key was broken until after completing the calculation. She wants your help finding the difference between her miscalculation (using salaries with any zeroes removed), and the actual average salary. Write a query calculating the amount of error (i.e.:act..
