1 00:00:00,890 --> 00:00:04,100 The next skill we will be going over is machine learning. 2 00:00:04,760 --> 00:00:10,640 Machine learning engineers on Upwork charge anywhere between $25 an hour to $50 an hour. 3 00:00:11,000 --> 00:00:16,880 And data scientists on Upwork charge anywhere from $25 to $50 per hour as well. 4 00:00:18,010 --> 00:00:25,870 Machine learning is considered a branch of artificial intelligence or A.I. and machine learning is basically 5 00:00:25,870 --> 00:00:32,140 the practice of computer science, where data and algorithms are used to replicate human learning. 6 00:00:32,410 --> 00:00:38,710 As machines learn, they show gradual improvement in their accuracy and in their effectiveness. 7 00:00:38,710 --> 00:00:44,710 So if you do have a passion for data science, computer science, artificial intelligence and cutting 8 00:00:44,710 --> 00:00:50,230 edge technologies, you may have what it takes to become a freelance machine learning engineer. 9 00:00:51,130 --> 00:00:56,740 Machine learning engineers, also referred to as data scientists, are responsible for designing and 10 00:00:56,740 --> 00:01:03,550 building artificial intelligence based algorithms whose purpose is to continuously learn to ensure the 11 00:01:03,550 --> 00:01:05,230 algorithms continue to learn. 12 00:01:05,260 --> 00:01:12,010 Machine learning engineers are tasked with assessing, analyzing and organizing more data in order to 13 00:01:12,010 --> 00:01:14,380 optimize machine learning capability. 14 00:01:15,330 --> 00:01:20,580 Freelance machine learning engineers are called upon by a variety of different clients across multiple 15 00:01:20,580 --> 00:01:25,260 industries to incorporate machine learning capabilities into their operations. 16 00:01:25,260 --> 00:01:32,130 So that's often undertaken as part of an organization's overall artificial intelligence initiative. 17 00:01:32,130 --> 00:01:38,070 And machine learning projects are often implemented to streamline different tasks that were historically 18 00:01:38,070 --> 00:01:39,420 handled by humans. 19 00:01:39,570 --> 00:01:46,440 Now, as a result, staff can be deployed to handle more customer facing value added tasks as more companies 20 00:01:46,440 --> 00:01:49,230 implement these types of machine learning changes. 21 00:01:49,260 --> 00:01:54,960 The demand for machine learning freelancers will continue to grow, which is why it is such a great 22 00:01:54,960 --> 00:01:58,470 skill to start to develop if you are interested in it. 23 00:01:59,500 --> 00:02:02,590 The machine learning skill set consists of the following. 24 00:02:02,740 --> 00:02:08,140 The first is principles of deep learning through understanding of the principles of deep learning and 25 00:02:08,140 --> 00:02:08,990 machine learning. 26 00:02:09,010 --> 00:02:15,610 Those are the skills that will help you and enable you to learn how to become a machine learning engineer, 27 00:02:15,610 --> 00:02:21,610 as well as leverage all the available technology to ensure the machine learning achieves its purpose 28 00:02:21,610 --> 00:02:28,360 while also handling the tasks that it is set out to do while also continuing to learn. 29 00:02:28,360 --> 00:02:35,800 That is really the whole thing here is that it's not only to solve a problem, but it's also designing 30 00:02:35,800 --> 00:02:40,280 it in a way where it is actually learning and getting better at providing that task. 31 00:02:40,300 --> 00:02:41,680 As time goes on. 32 00:02:42,430 --> 00:02:46,250 The next skill in the machine learning skill set is software engineering. 33 00:02:46,270 --> 00:02:51,430 Now you want to have some software engineering skills because machine learning engineers should be adept 34 00:02:51,430 --> 00:02:57,520 at handling a variety of different software engineering responsibilities, including writing algorithms, 35 00:02:57,520 --> 00:03:00,190 natural language processing and more. 36 00:03:01,040 --> 00:03:02,720 Next is data science. 37 00:03:02,750 --> 00:03:08,600 You want to have some sort of familiarity with data science because a machine learning engineer will 38 00:03:08,600 --> 00:03:15,330 be dealing with a large data set and they need to know how to process them via Python, Java and SQL. 39 00:03:15,350 --> 00:03:21,110 In addition, machine learning engineers should have knowledge of data modeling, big data hypothesis 40 00:03:21,110 --> 00:03:23,540 testing and mathematics proficiency. 41 00:03:24,220 --> 00:03:31,000 And lastly, problem solving skills is a very vital part of a proper machine learning skill set. 42 00:03:31,030 --> 00:03:36,820 Now, machine learning is no different than any other type of project where you are going to be problem 43 00:03:36,820 --> 00:03:37,360 solving. 44 00:03:37,390 --> 00:03:43,210 However, as a machine learning engineer, your job is to actually write the algorithms designed for 45 00:03:43,210 --> 00:03:43,960 automation. 46 00:03:43,960 --> 00:03:49,840 And this is where some of the challenges and obstacles come up, that it's your job to overcome those 47 00:03:49,840 --> 00:03:55,030 and to deliver solutions that successfully streamline the intended workflow. 48 00:03:55,030 --> 00:04:00,610 And it's all about replicating the human logic, and that is what requires extensive software development 49 00:04:00,610 --> 00:04:02,530 and problem solving skills. 50 00:04:02,530 --> 00:04:08,950 And even before they occur, machine learning needs to pretty much understand when a problem may come 51 00:04:08,950 --> 00:04:14,530 up and then have that machine actually be able to handle it and solve it itself. 52 00:04:15,510 --> 00:04:20,820 So to summarize, as a machine learning engineer, you want to focus on your problem solving skills, 53 00:04:20,820 --> 00:04:26,700 your time management skills as well, because excellent time management skills allows freelancers to 54 00:04:26,700 --> 00:04:32,550 successfully juggle complex and competing priorities and arrive at solutions that meet their clients 55 00:04:32,550 --> 00:04:35,460 objectives as well as communication. 56 00:04:35,460 --> 00:04:41,250 Because most machine learning projects involve extensive teamwork and collaboration with various different 57 00:04:41,250 --> 00:04:42,090 stakeholders. 58 00:04:42,090 --> 00:04:49,050 So communicating effectively in writing as well as verbally goes a long way in eliminating misunderstandings, 59 00:04:49,050 --> 00:04:55,440 as well as providing project clarity and articulating potential alternatives that may be more suitable 60 00:04:55,440 --> 00:04:56,250 in the long run. 61 00:04:56,250 --> 00:04:59,460 As it relates to the Machine Learning Project that you are working on. 62 00:05:00,660 --> 00:05:02,370 As a machine learning engineer. 63 00:05:02,400 --> 00:05:06,990 A healthy curiosity, especially regarding technology, is important. 64 00:05:07,020 --> 00:05:13,320 Virtually all computer programming and algorithm based work involves a high degree of curiosity. 65 00:05:13,350 --> 00:05:19,380 A healthy curiosity often separates exceptional freelance machine learning engineers from average ones 66 00:05:19,380 --> 00:05:21,570 who struggle to find work in charge. 67 00:05:21,570 --> 00:05:22,830 What they are really worth. 68 00:05:23,700 --> 00:05:30,450 To summarize, machine learning engineers typically charge a median hourly rate of $25 an hour to $50 69 00:05:30,450 --> 00:05:38,130 an hour, and their top hourly rate is $100 plus per hour while the demand is medium and the competition 70 00:05:38,130 --> 00:05:38,790 is low. 71 00:05:38,790 --> 00:05:44,220 So once again, just like with data visualization, the demand is pretty substantial. 72 00:05:44,220 --> 00:05:47,520 However, the competition isn't that intense. 73 00:05:47,520 --> 00:05:49,800 So this is a great skill set to get into. 74 00:05:49,830 --> 00:05:55,470 If you have everything we went over, if you have that curiosity and you are deeply interested in machine 75 00:05:55,470 --> 00:05:59,850 learning and A.I., this can be a great skill for you to develop. 76 00:05:59,850 --> 00:06:01,380 I'll see you in the next lesson.
