What Are The Different Types Of Machine Learning
There are three types of machine learning:
Supervised Learning
In supervised machine learning, a model makes predictions or decisions based on past or labeled data. Labeled data refers to sets of data that are given tags or labels, and thus made more meaningful.
Unsupervised Learning
In unsupervised learning, we don’t have labeled data. A model can identify patterns, anomalies, and relationships in the input data.
Reinforcement Learning
Using reinforcement learning, the model can learn based on the rewards it received for its previous action.
Consider an environment where an agent is working. The agent is given a target to achieve. Every time the agent takes some action toward the target, it is given positive feedback. And, if the action taken is going away from the goal, the agent is given negative feedback.

How Is The Apple Interview Different From Other Companies Interviews
The Two Against One style of interviewing is somewhat unique amongst the FAANG companies. This style is what it sounds like in that you are being interviewed by two Apple employees.
Outside of that though, the content you will encounter here will be very familiar to you, especially if you have read up on the other posts here on Byte by Byte that cover the and the .
Another difference may be in the enthusiasm that Apple employees have for their products. While its not mandatory, being an enthusiast and user of Apple products is a soft prerequisite. Of course, it wont be a make or break a thing if you are not, but it will probably raise a few eyebrows if youre enthusiastically against Apple products.
Find All Sum Combinations
The goal of this exercise is to use your backtracking skills to find all sum combinations.
Problem statement: Given a positive integer, target, print all possible combinations of positive integers that add to the target number.
The output will be in the form a list of lists or an array of arrays, as each element in the list will be another list containing a possible sum combination.
For example, if you are given input 5, these are the possible sum combinations.
1, 42, 31, 1, 31, 2, 21, 1, 1, 21, 1, 1, 1, 1
Try it yourself below before checking the solution.
vector< vector< int> > print_all_sum{ vector< vector< int> > output
We recursively go through all possible sum combinations, and when the running sum equals the target, print that combination.The algorithm will recursively check all the numbers that can sum up to the target.
In each recursive call, there is a for loop that runs from start to target, where start is initially 1. current_sum is the variable that is incremented with every recursive call.
Every time a value is added to the current_sum, it is also added to the result list. Whenever current_sum equals target, we know that the result list contains a possible combination for target, and this list is then appended to the final output list.
Base condition of recursion:if current_sum equals target print the output contents
Before each recursive call, an element is added to result. However, after each call, this element is also removed from the list to reset the list.

Getting In Touch With The Recruiter
The first step in the process is to either have a recruiter reach out to you or vice versa.
In the former, it is not uncommon for Apple recruiters to reach out to you if you are graduating from a competitive computer science program, have competed in hackathons, or have a compelling enough web presence to get approached by recruiters through LinkedIn and via other online channels.
For the latter, the most direct method of being put in touch with a recruiter is directly through the Apple Jobs board. The layout of the website is characteristic of Apples style in that it is very minimalistic and has a very clean-cut style.
Depending on your experience and their need, you may or may not receive an initial rejection from the automated system. Apple is typically quite good about sending a notification in either case.
If the position is not a fit, you will receive a response, and in the event that it is, a recruiter will touch base with you for further details, some of which are outlined in the remaining part of this post.
Another direct method is to keep a lookout for local job and career fairs where Apple will be present. These tend to be centralized in more densely populated areas, which makes sense from Apples perspective in having a high number of qualified candidates.
It may be worthwhile to see if there are any local channels, that is, universities, meetup groups, etc. that may give some location-specific information for your area.
Apple Machine Learning Engineer Interview Process
The interview process for ML engineer roles at Apple consists of three rounds
- The Initial Screen: A recruiter from Apple will get in touch with you to understand your skills, compensation, level of experience, and what your expectations are from the role. Youâll be contacted by the recruiter either through LinkedIn or directly if youâve applied through Appleâs careers page.
- The Technical Screen: This remote interview round predominantly tests your ability to solve coding problems, mostly around algorithms. A hiring manager conducts this round to understand your prowess with programming and your ability to display sound analytical abilities in solving problems. This round either takes place via a shared doc or an interviewing tool. Apart from the coding element, you can expect a few questions around ML and AI as well.
- The On-site: The on-site interview evaluates your coding skills, ML knowledge, and behavioral tendencies. If the role youâre applying to involves product design, you can expect a dedicated Product Design round in the on-site. Each of these rounds is conducted by one or many hiring managers. The rounds are usually time-bound, lasting about 30-40 minutes each.

What Is Naive In The Naive Bayes Classifier
The classifier is called naive because it makes assumptions that may or may not turn out to be correct.
The algorithm assumes that the presence of one feature of a class is not related to the presence of any other feature , given the class variable.
For instance, a fruit may be considered to be a cherry if it is red in color and round in shape, regardless of other features. This assumption may or may not be right .

Explain The Difference Between Lasso And Ridge
Lasso and Ridge are the regularization techniques where we penalize the coefficients to find the optimum solution. In ridge, the penalty function is defined by the sum of the squares of the coefficients and for the Lasso, we penalize the sum of the absolute values of the coefficients. Another type of regularization method is ElasticNet, it is a hybrid penalizing function of both lasso and ridge.
