Summarized By: Jeff Musk on Thu Feb 06 2020
so I after. So my impression degree waas is in more like a statistics industry engineering organised on Ben. My area. It's more like in Marty very statistical, modern or manufacturing process. Right? So after that, I was thinking about it. I need to do any interesting to go some kind of medical stuff. So I went to only I resemble State university to do marry Paulist all. There was a kind of interviews, Prince ready research opportunity there. So I went there. I started working here. The kind of neuro engineering mostly working on hold to model the neuron systems off now. Human primate assistant. Your amount of animals after that say estate what years? And you're going to be you. Mercy for my post. All I decided. Hey, I would like to really want to go on the industry because the industry more exciting to me on that, huh? I joined a small startup company. You said you go all that time. She's financial consulting company. Kind of big talk financial consulting stuff. That's a purity. A more like a mercenary company. They they want different clients. The field models build mercenary solutions for them like a customer churn problem for detection. Problem are, you can't scare There is some kind of problems that how do you know how many days a patient He's going to stay in hospital for years? Right? That because that's a critical issue for the the Chelsea Trail of Carrie Insurance company. So but actually very interesting. Experienced There was that I actually I did not do really customer party, but my manager put me on to upended in. It was kind of emotionally competitions such as community Cobb, cable competitions. The reason. I guess the company is benefited from these kind of dubious because we're small companies, they need to have some kind of check records in different problems. So I was my I spent about two years. They're spending most of the attending those competitions on the pretty will in some of the competition, such as kidney pickup till rock number two, something like that. So yeah, that's really a good experience for me, especially, you say truly, especially from you. From my background, I work from study area but really emotionally, emotionally started from statistics probability. But actually it is more is way more advanced than then. Those kind off missed orgies. You can learn from that. It's just right. So that's really give me opportunity toe polishing my emotionally skills to get exposed to different moments such as recommendations such as feels care such as financials, etcetera. So then, yeah, so after that I I spent about two years doing those competitions and think, OK, I really need to be on your hands are really industry probably because the difficulty for the village, the challenges that you are not going to be who bean encountered in mercenary in you come mercenary competition is that in those competitions that they tell you screaming for you, most of them Onda, the problem redefined to you right on. All you want to do is to try different features you nearly missed already tried different, uh, different modeling missed orgy I were than something exactly improve your ranking. But once in several scenes, that's a missing on also critical industry. That really mean you need to be able to understand the business problem and try to translates that uses problem into some rational solution. That's something using also, in real life, they don't always prepared to you. You have to heal them. Are be ableto handle the different types of data gives men have, which is messy. So I decided to draw on, Leave the company on the night on the warm up laps in woman outside. That's also very interesting when we're there. We were I was not too emotionally. You keeps me the opportunity to be exposed to be later in the warmer every minutes off unit of Uber's I used the war mother come to shop. They have a lot of the hand. I was able to say they're on the practice. That was kind of the tools that is high, but he whatever. And I was living in a small team to pull some kind of internal Colonel Tool business intelligence called dashboards for the well being of use. After about 1/2 year, I'm still in Houston. My, my, my work, my life, emotionally blindsided by the hair and reading books to some was really some kind of fast machine. Learning was kind of high tech companies, so that that time I got the opportunity to work for Microsoft and I moved to Microsoft in the Europe in 14. My line. Uh and that's where I am. No

so so mean my current een. We are working with external capital partners on Microsoft, right? Extra used t give you some example. Names off the external popular's way were mostly working with all those kind of big enterprises such as you can't be. Yes, a Nestle can be, say, cities on the Starbucks. Those candy warm. I can be kind, The only company, right? So, Yuri, while we do that which car? This customer they called in customers off us or patters that you have no kind of problems e to the up other, either regular business operations. Right? So they feel because they have data, they have something that they want to build some kind of cloud based this devotion, they feel the those kind of solutions can be careful for their business way show to us when we jump in to understand that their business problem and trying to propose some kind of emotionally solutions on also you. This solution does not only include the emotionally model, right goes on, figure out how you can you know why this mother into their production system so that they can use our regular bait, right? So that's Connolly. That's my, uh, this major responsibility. It's year two that work with partners. Toe toe. We go out to design a mercenary solution. Hack older business problem. Right. So our weekly are so because we are condoms supporting. I mean, no matter where these cost customer is from, so you can be from Europe. Can different Asia can be from South Africa, uh, from South America. Whatever. We're global wise words. She's way we need to many times. We need to go fly into the customer side, walk with them to discuss with you understand their business problem. Toe Very Cleary on them. Come up with the machinery. Social. So So roughly we travel Armenia. I traveled to be about 20 to 30% of the time. Uh, little wise on the the many time. I mean, for my car. Stop these pretty vegetable. Flexible. Unless you have a meeting, you need You meet with someone in personal human crap to come to the office. But otherwise you can. You have the freedom to work anywhere you want. You can work through the on your phone office, we all your homework. Some could start a tail or something like that. So Yeah. So also, these days you know those kind of virtual meeting such as Microsoft teams where banks all resume sometimes that so you can use all the world is different virtual channels to meet with with your either police within Microsoft are your partners external.

s o these days because of the, you know, emotion green or a i d pairing the very, very popular off very about solution Bunning. Different problems, right? So, so high smelling Very so you before it running. S o r on the price off the most talked about you a popular in tools. People didn't send his issues right off course. Our use more and more popular you need People were always statistical backgrounds on the price on it's more like a more popular in the hole. Where is more inspector reason you're back. Well, the ground, the other the merging off the emerge, the theory rising off the deep, earning so so pious signs more advanced than you talking about gardening for s o. From that perspective, we were mostly high. Some here. I'm talking about deep yearning for him work that a lot of people from work for money is the most popular ones are just pencil roll on appearance. Pytorch is also coming up very quickly. So we are also depends depends on also with the tour which shoes most many times Utah also because way when we work with partners, we also we young people collaborating with our partners. Where I sit, for example, we have you won project. We have a signed his work from my personal, but we're also expecting to take a census from the other side. So you really would shoot the framework off the scenes that the partner is comfortable, ways or the like. Once every department might be more familiar with our but with the Assad as they are, they are. You have the intention, but there are still too high sound.

What things do you like about your job? Were there any pleasant surprises?

So the the scene, I think other said now our job is working ways. External partner Spry So we were on a project for one partner for the truth three or four months. Then we did never. When you've ever between two, their production symptons and we'll be right. We leave this project and then we jump into another part. So that means OK, every other while So every through two or three or four months, they're always running into a new challenge. Right? So sorry the challenge might be summer. These from Mersin Element sports wise might be similar about for the business problems might be right. So you always get these falls with deeper in bastion We are deep friend fractionally missed or itchy so that that's really makes me kind of excited about the work. All right, so you are saying that the UK on instead we are partner might be global, so you might get the chance to travel to people Order off this word. So that's also another kind of exciting experience for you, as ah has Ah kindof I mean, your work is sponsoring you to travel across the war. That's a very good experience for your life

Also, as I said when we worked with extra off your solutions for our experiment partner, it's your nationally, just one component. Until a solution. The jury is underpants. Emotions, especially. It's a mercenary model. You when when is making predictions, just needs to get that have from somewhere. So you need to have a pipeline. They have a plan to get it on customer assistant into your into your you know, her parents off mercenary model the only so he can be consumed by the model. So that means okay, many times we have to collaborate was developers write software engineers because they are one who is responsible for building imaginary people. Yeah, So you are many times off Roger's being already you to work with some kind of a project manager. They're goingto help you to know the connection between between folks with the Microsoft are not so keen on customers. So is all of this month thing, miss Three typical tables with crab. So the most efficient way to be working with them that Yuri for project we worked with, we have to go over to major groups of people. Please, who are actually coded. Why is the developer of the sentence. So you need another to me to make sure that, uh, both parties can work one more efficiently. The best way to make that that makes it happened that you both developers on dating scientists think more of ya Lost interview speaking to party, right? You're agreeable. They want you, they say, How the fucking means that all of the one you're trying the no mother wants call you way concerned. We got through with the model, so let them overcome addiction. Right? So once you have the interface redefines on the post party, it's come work. So that's mostly patiently. Otherwise, the whole oppression the old fashion off emotions hopeful. Deploy the machinery models that Okay. Beans, tomato armed in the call, the boat parts that hair. I have a model employee, right? So that's not the most division with these days. We have ah, waste will deploy the modified. They sent it to themselves. Can't see company remain angel clinics

What major challenges do you face in your job and how do you handle them? Can you discuss a few accomplishments?

Based on experience at: Principal Data & Applied Scientist, Microsoft
Summarized By: Jeff Musk on Thu Feb 06 2020
So the major challenges? Uh, I think that, um So the first of major manage is that okay? You have to even before you before you jump in to build the model, you have to understand that is his problem. Customer has, right? Yeah. As I said, we running into different business park problems was different. Popular's every other while every true three or four months sounds about right. So every time we will start a nuke, new engagement or new project, you have to really understand the business problem. You have two mothers understand why the customer meet needs this kind of solution you sponsored by this partner. How wants the art? You know, that's really are very critical scene. Because if you start, if you propose it wrong, the long promotional solution that's a disaster. But her party, right? So that's the first challenge you will encounter the second challenge me that okay these days, Although you can't find footfall almost every say problem. You can be fun to some kind of discovery posturing. Looks like those repositories kind be used to tackle your business. You probably problem once you are just right. But based on my experience, in bomb off them. Cast, huh? I have never seen anyone of them coming directly used to tackle your problem. You'll have to make some change or you either you had You have to have good inside. The business problem you have through the inside have have could be inside to the to the U. So the kindof sirrah screen these algorithms who are using right the based on that understanding, you make some problem, make some change for the meticulousness ocean, get from open space and then you come. That's the only way that I can make it work. For most of the problems you have a second. This day is also home. And he's thinking about hey machinery in as I envy me They turned quietly burning have made it work. But that's not true. You need you have got the inside of the visit Probably affected. Also good. Really Get mother thanking the to these words and natural. So the few accomplishments One scene I think when we have ah published paper all because of pasta is talking about how I'm healed. The, uh, happened observational deconstruction to Paco to assess the acne is diverting level based on self images, right? So will you were in this part that we were working with bestest yourself. We were trying to. So that's it for this for acne assessment. You early people have two patients have to go through with the largest operated vehicle. That's very either come counseling and knocking company. Not convenient for the customer. Yuri. They're happy with one month or something even longer together, off women. So now we have. We have. We have cellphones, smartphones. The destruction will be all for the nest. Ms. Kane tells me that we feel the mercenaries promotion. You promised erosion so that the customer can just take the self English on they the you read their This is virtually never waas assessed by the by the way I heard it model. So when we feel this solution, which is is the performance from the accuracy off, the tomato is better is anything is better than the largest. So that's a really good Children way have achieved so far

way Talk about recent developments in the Marine. I think the fourth growing has to dimension as the pop. It just growing very fast. You different. There are a lot of new agrees and coming out new with our applications coming out right. So I think those are the used things. If he's changing or you just, um you just bring in the machinery in I Europe so originally released emotional you have together do very, uh, with a handcrafted reach, engineering under tow to make your mother work right on out of these days because Richard, you nearly is still very important. But now these days, especially encumber separation or natural language because it's in those kind of picture in January, it's morning burden on the low down fishing here is significantly reduced in most areas. So I think that, of course, the lots of eyes are after the D printing coming out. Uh, when the area off the mercenaries border because of this new guy mythologies So that's very cool. Very good. So so, so back off course. When you these days, when a very important scene, you have to be very careful about how aware and comply I return you the above calling responsible act right. You have to be able to protect the privacy of people who have toe protect the combo of each George's purity of the data. And also you have to be ableto avoid discrimination model. Right? So there's a very broad their homes being a very broad discretion regarding those kind of responsible. Yeah, they're careful.

well, the current process for this role, Yuri said example, we have openings way we'll go to different the HR people. It's going to go to the job post outside such as the bean Caribbean girl took so figure to do some theatre in because the candidates then we would have ah one s o h ard after the HR sculpt down toe, leanest all candidates, their country chose kind of this. Um, there are several chocolate stream with instructions. Not you need sponsorship for your for your working information on what's the degree? What condo working you have before, So that can't those are hardly apartments. You're excited for the same team, right? So of course we my machine, we wouldn't just Jeez, we also have a lot off undergrad college graduates. Some Massport is something like that. So one coursing that you're really you can get some kind of summer internship opportunity. Was Microsoft that come with the hiring process? Much? Is there for your computer off course, The home of the summer internship interview process? Roughly the same. That's the turning point in the process way. Call this the stand sundered for a summer internship because of course. If you can't get into the summer internship, we can't get the opportunity to work with you in the summer. Tommy, you did pretty well and you will get the opportunity to be there to pull another summer intern. You don't get it full time employees offer after you graduate. So that's the same home. So then after it. So back to the FT hiring process I should keep after the A round off HR phone interview there could refer the scope down toe. Smaller, smaller, least of people. The rebels have. Ah, one wrong Max money to round up my interview to make sure that you're happy. Uh, right. Data science background on your safety young, we will check with you. What is your? That is big background with your money. Everyone's on with your price on language is called me, not with recording capability. Most important for me, while you do, people will look whether he has a knee off. He or she has a need. Uh, they sent sense, right? So because that's more important than you money. Others, right? So what's that? He's had you become successful success with past the point of the book welcome. Invited me to be on campus too, to meet with four or five books with gin to make sure that we are personality wise. You It's easy to collaborate with you.

When I when I interviewed for my for that Cindy of company after I a variety of the Arizona's the university, the interviewer asked me one question said we don't you? He's more like a fraud detection credit card transaction for detection problem, right? So when she asked one question, Uh, assuming that you are based on your your purchasing place trades that way. You know Paris. What here? Something's happened that way. But we know your typical since the typical says you buy the kind of gross ruin some Windows foresight owns on some kindof um, some crow. Something exact. Right? So all this started in your transaction happened. There's once very strange in that things happen that you bought a kind of old write online. There's no credit card. They'll soon about your happens. Then you got a on Army corps from the credit card company. Why they are calling you something like that, right? Suddenly, you many times commercially problem this situation that although you're working on this problem, but you have put your feet in the shoes off as the one in that area on the many times will have the experience right while you're having it.

Thank you's come bur just the Yulee son condo so long you just your daily job could be just around some running from secret prairies to put the application But they announce this or build in some kind of bash sports out for business Use it. So that's also thinking late twenties work. Another kind of business works more like, Oh, just because you feel the mercenary in models for basically it's so provides much money model on super model. Well, he's been about yours, but also with the Microsoft there, some other incidents were It's like it's work. It's more like a funeral business, right? So that means with Allstate sends provisions are facing more than just a portion of the tools that I didn't sense. Mercenaries Devotions Off service is Microsoft Visibility Asia Freedom. Those lectures strain all. There's another for the force. One would be something like that. Well, yes. Being back home for Michael for research 100 search hundreds. So there are lots of other things and he's working there, So they are. So these are the four different rolls off with scientists with Microsoft. So so course you've You mean the difference between those 40 barrels? That one's better steam for us, Mike, that external basic right customers, let me is okay. In addition to those kind of hard skills such as you should be able to I understand the difference. You have experience on expertise, seen the three industries, but such a refill. Just professional. What? We also need you Those are we calling? Consider Daniels. Actually, there are skill or something. I also you need to be able to understand how you tackle that. They hold you on their help. You feel the machinery solution goes out from Bihar skills. Another didn't stop steel with unsavory. That'll help you help you trace. Hold the communicate with the customer. Right. So now that is not steal. So I mean, uh, authority won't you move from the other three different types off the rolls off? They started moving you off my current organization. You might have to take some time to build up your off steals called to please the customer help you control the expectation of customers. Right. So that takes time. So yet you love you, you drunk ass ways

so, especially from the warmer. Um So I was leading a small teen. We are building. The internal dashboards will help the fortunes. People merchants to understand want items they need to power has olive one for the commercials. They need to make sure they need to understand what? What I what kind of demand these trendy overtime, right? Every level you stir is common. They might want to know what items people are kind of assertion a lot on their only warmer account size so that they can be prepared for the well. That was kind of a canyon givens, right? So you'll be yesterday's commune 45 weeks earlier. These was concerned queries are increasingly beginning. Right Was know that they want you avoid that metes. The items are also stock so that the articles and opportunity So then why? What will we be that you don't really want to basically travel high? They wave which records all the queries people assertion warm, other common. What I have decreed. What happens bar something that's that around some high priest to understand the true and understand which I think a popular or something like that. Then we'll be able to deal with the president This kind of ministries without my dashboard so that you don't have to. I always work on those kind of apple buries those things come mixed The herb posits morning picture.And what about working hours? The war? Mind that we have a condo policy, I guess that's probably very common in big area that you can choose who work from home every Tuesday, or search that eventually you have two days to chose to stay home. I guess they were one reason behind this. Is that because the house party so, so hard there. So people anybody be far from the office or save the town six then.

So I think one scene I saw were at that time, we took 10 courses before you can apply for master degree there. So one of the several courses, I think there are very useful there on. Also, prepare me ways. Those kind of studies go sinking poll, uh, some fundamentals for mercy Lord, in such as the, uh, we have ah course called the Partition. Her presentation off model. Right. So that means oka Also at that time, we worked the models with heart the air war mostly kind of nearly your models near linear regression re traditional lawsuit. But it gives you helps you to understand the prediction result is that how to interpret your prediction results? How do you interpret your coefficients off the model house contest? The significance off the coefficients, right? Those gave you the candle. Really? A statistical sinking towards the machinery because every says a status every many kinds will have to encounter this situation is actually model features selection last year.
