Supervised Learning: if you are training your machine learning task for every input with corresponding target, it is called supervised learning, which will be able to provide target for any new input after sufficient traini...
LeetCode Question Write a query in SQL to obtain the name of all those physicians who completed a medical procedure with certification after the date of expiration of their certificate, their position, procedure they have done, date of procedure, name of the patient on which the procedure had ...
and is the learning rate, the parameter we need to tune for the algorithm. This parameter determines how fast we move toward the local optimum. If is too large, we will miss the optimal point; if is too small, the convergence process will be inefficient. ...
DS Interview Question Are expected value and mean value different? LeetCode Question Write a query in SQL to obtain the name of the physicians who are trained for a special treatment. Sample table: physician Employeeid | name | position | ssn ---+---+---+--- Sample table: procedure co...
5. Once you get the optimal model, you can publish this model to production using a pickled model (in python) or POJO (in java). This model can then be queried by using the exact same process of cleaning as done in #2 and #3 for the new articles. ...
How would you handle overflow for very large input integers? 【解答】在最开始的两个数定了以后,后面就一路计算和检查下去,看是不是 additive number 就好了。因此在最开始使用两层 for 循环去遍历前两个数(整型)的各种可能的组合。 代码语言:javascript 代码运行次数:0 运行 复制 public class Solution { ...

Notes: It is intended for this problem to be specified vaguely (ie, no given input specs). You are responsible to gather all the input requirements up front.Update (2015-02-10): The signature of the C++ function had been updated. If you still see your function signature accepts a const...
Should we even treat missing values is another important point to consider? If 80% of the values for a variable are missing then you may drop the variable instead of treating the missing values. Deleting the observation...
This is a good way for interviewers to test for the team-collaboration spirit of the candidate and also if he can figure out a way given a particular situation. A good answer would be: This situation typically happens while training models offline and getting them into production, since the ...
