Learning Objectives

  • An AI skills gap exists for ML applications.
  • For Industry 4.0 environments more AI and ML knowledge is needed.
  • Education needs to change to help AI and ML.

Artificial intelligence (AI) talent is difficult to find, and few industrial companies have enough in-house AI talent. AI will transform many jobs, and companies should give every employee the knowledge they will need to adapt to new AI-enhanced roles. AI resources help implement new business models and better services, but user acceptance is required.

During the last decade, AI design, development and implementation has expanded in many sectors. Organizations are struggling with AI business potential understanding and with finding AI talent.

A growing number of countries have recognized the opportunities provided by artificial intelligence and have prepared a national artificial intelligence strategy. In 2017, Finland was among the first countries to launch an artificial intelligence program. The objective of the program was to make Finland a leader in the application of artificial intelligence.

The Finnish Artificial Intelligence Programme identified a small portion of companies as forerunners in AI implementation, with the majority of companies still being at the early stages of using data and AI in their operations.

How to address the AI skills gap

A way to address the AI skills gap is to increase resources for digital, math and technical education in general. In addition, the current education system in Finland does not yet pay enough attention to applying AI in different fields. Academic and training programs are unable to keep up with the rapid pace of innovation with AI. AI education should start early and take place for every education stage. Academia, companies and public sector officials must work together and ensure comprehensive AI curriculums will be available. Massive open online courses (MOOCs) show the way and are a good example of a modern way to educate masses with basic AI knowledge. However, deeper understanding often requires tailored education modules.

The manufacturing sector is currently lagging behind in AI and ML use compared to many other industries. Adopting new technologies, especially in process industries, requires pedantic planning which is time consuming. Companies have long histories in optimizing production, and as the life span of investments can last for decades, changes cannot be made rapidly. In addition, the safety and environmental regulations require strict governance.

Drawing from the sector estimates of the PwC AI impact index, PwC [formerly known as PricewaterhouseCoopers, a professional services firm] estimates that by 2023, individual industry sectors may increase operating margins (how much of each euro of revenues is left over after both costs of goods sold and operating expenses are considered) by 60 to 100%. The difference in the industry specific “AI boost curve” shapes reflect the impact of two factors: 1) the speed the industries are capable of adopting different AI applications and 2) the AI solution development to address the industry-specific business issues.

AI manufacturing benefits

In manufacturing, short-term benefits are expected to mostly come from process automation and productivity-based solutions. In the mid-term, more complex processes can be automated as intelligent automation offers considerable potential, and predictive maintenance and optimization applications further boost performance.

Productivity gains from AI and ML are not only dependent on the introduction of the technology itself. There also is a need to change the organization of work and increase employees’ knowledge.

Skills gap in artificial intelligence adoption

Research shows the biggest barrier to AI and machine learning adoption is the skills gap. Most of the time, surveys refer to the technical skills needed to develop AI and ML solutions. However, the biggest skill gap in AI and ML spans across the organization.

The Finnish Artificial Intelligence Programme end report pointed out that based on its survey, Finland has high quality education for those aiming to be AI professionals (information technology, mathematics), but there is a gap in the AI applier field. In these fields, the effects of AI would be seen fastest. The working group stated that to achieve the ambitious AI targets, the most important things are to ensure versatile education will be available, investments are made in new education methods and programs are created to attract talent to Finland.

Continuous education of current employees is a challenge, and different operations and mechanisms are needed to address these concerns. A critical factor is to increase management awareness and knowledge regarding the opportunities AI will bring. This is how enough input can be secured for new flexible education methods.

AI employee competence requirements

Employee competence requirements are affected by the changes in the work demand in the job markets. The need for new talent is increasing at a rapid pace in tasks where AI will be developed and applied. This demand cannot be addressed by the usual education path. Rather, new operations and mechanisms are needed to help improve existing employee skills efficiently.

Much of the employee competencies are based on the on-the-job learning, and thus companies have more responsibility for competence development. Companies are actively seeking for ways to re-educate employees internally or in co-operation with other companies.

There are numerous approaches exist to educate, but little workplace learning in Industry 4.0 contexts exist. Organizations need an adequate performance appraisal strategy and adequate workforce training with self-regulated, reflective, collaborative and blended learning to lower risk of excluding workers from Industry 4.0 environments. Organizations without adequate training risk impacts on production efficiency, product diversity and quality.

Companies need to equip existing professionals with the AI skills to apply their knowledge in the AI-driven world. This is supported by a 2018 study of Future Workplace and The Learning House, which highlights that training the workforce for AI and ML skills could be the efficient way to fill the skills gap.

Letmathe & Schinner (2017) state the success of workers will depend on flexibility and problem-solving competencies as well as willingness to engage in lifelong learning; otherwise workers will be unable to keep up with the required changes in their workplaces and work procedures. This challenge also might explain why many companies are reluctant to invest in cyber-physical systems (CPS), which often includes AI. Competence management on the organizational level, as well as the reform of public education, are important factors for introducing CPS.

Case study: Machine Learning Academy (MLA)

Free and general-level online training on AI and ML is available from major technology providers (such as IBM, Microsoft, Amazon and Google) or from MOOCs organized by prominent universities.

An example is “Elements of AI,” a 6-module online course created in co-operation by the Finnish technology company Reaktor Ltd. and the University of Helsinki. Typically, the aim of this type of training is “to demystify AI” to encourage a broad group of people to learn what AI is, what is it good for and what are its limitations.

Machine Learning Academy (MLA) from Dimecc Ltd. in co-operation with Futurice Ltd., is a focused and industry-tailored approach for closing or at least narrowing the AI competence gap. The first course focused on the Finnish machine manufacturing industry in fall 2018. The second course closed at the end of April 2019. This initiative was also highlighted in the final report of Finland’s National AI Programme as an innovative example of AI-related education.

MLA’s primary target audience consists of research and development (R&D) supervisors and engineers as well as business and product owners who are managing and/or participating in AI/ML development projects. To succeed in these tasks, they need to understand how to specify, plan, evaluate and manage development or insourcing of sub-entities that contain elements of AI and ML. For example, for R&D engineers it is important to understand how introduction of these new technologies will change the capabilities, boundaries, schedules and interfaces of their product development processes. After the course, participants will have an understanding of the fundamentals of AI and ML as well as an ability to recognize and manage development tasks that aim to benefit from use of these new methodologies.

MLA consists of seven full-day training modules with supporting pre-reading materials, hands-on exercises and homework. The training starts with high-level topics, such as reviewing typical business drivers and examples of ML applications.

In the more technical modules, various ML methodologies are covered (supervised learning, unsupervised learning and deep learning), followed by data understanding and ethics of AI. The sixth module helps the participants understand how real-life AI/ML projects are executed, and course projects are reviewed in the last module.

Throughout the course various types of business and technical canvases are introduced and used as learning tools. Their main purpose is to help the participants understand where they need to focus and which stakeholders they need to engage with during the different phases of data science projects. For example, the “Business Objective and Context” canvas used in the first module directs its users to work together with business owners and those who fund the project when answering questions such as: “What is the business objective [of this project]?” and “How does it fit with our business strategy?”

Cross-disciplinary project team expertise is often used in a typical data science project.

Given MLA’s primary target group, it is not surprising in their feedback the participants appreciated getting more understanding on how ML projects can drive and shape actual business impacts. Also, topics related to preparing and running practical ML projects were valued, such as data preparation (collecting, cleaning, pre-processing, filtering, analyzing, etc.) and comparison of different ML methods. According to one participant, “Often we do a lot of work just to see that we are stuck with insufficient data.”

Students plan and specify a machine learning project

During the MLA course, the participants are expected to plan and specify a real machine learning project. The course modules are arranged in such a way that their content follows the flow of a typical ML project (see Figure). The course arrangements also provide the participants with several opportunities to discuss their projects with lecturers and the other students and share and compare their approaches.

To complete the project assignment, the participants also need to get contributions from various internal stakeholders, such as business and process owners, technology developers and product managers. As topics related to the course project are introduced and addressed throughout the course, the participants are encouraged to engage with these stakeholders and get their commitment to the new approach. The aim is by the end of the course, each participant has a project specification which key stakeholders are already familiar with and which is detailed enough for starting an in-house development project or sourcing it from an external supplier. In the spirit of co-creation, each participant presents a course project in the last module at an appropriate level of detail.

Although the participants of the first MLA course came mainly from R&D, their project topics covered a wide variety of companies’ internal functions, such as finance (smart cash forecasting, customer risk analysis), sales (pricing and tool, automated offer generation), manufacturing (intelligent scheduling, process control for quality optimization), customer care (predictive and preventive maintenance) and human resources (improved competence development through job market analysis).

AI field project for machine learning

A concrete example was Ponsse Plc´s field project, which focused on after-sales services, especially field maintenance of the harvesting equipment where ML was used to recognize the needed oil change interval. Hydraulic oil and filters are currently changed at fixed intervals, approximately every 1,800 hours, and optimized change interval would mean remarkable savings.

MLA lasts about three calendar months, and the planned total effort for participants, including the project work, is 100 working hours. Feedback and experience from the first two MLA courses suggest this is enough to achieve the planned learning targets, depending on the participants’ ability to study on top of their daily duties. Also, the course project seems to be a good way to make the learning more concrete and get commitment from various stakeholders.

Learning about AI, machine learning

The skills gap in ML adoption and training has implications for the manufacturing and machine building industries.

Although the skills gap is likely to remain for the foreseeable future, there is clear need for tailored AI/ML training programs to help companies develop employees and encourage them to start experimenting with AI.

Four ways to improve artificial intelligence, machine learning education

Recommendations to help companies, academia and governments companies with AI and ML training:

  1. Develop a customized curriculum for your industry.Instead of trying to compete generally in AI with leading tech companies such as Google, we recommend becoming a leading AI company in your industry sector where developing unique AI capabilities will allow you to gain a competitive advantage. How AI affects your company’s strategy will be industry, company and situation-specific.
  2. Focus on educating the whole company personnel.Rather than establishing separate AI units within the organization, we recommend that AI competencies and understanding should be increased at all levels – from the management level to the shop floor. The same principle applies on the society level.
  3. AI training should encourage concrete pilots and use cases.Build AI training curriculums that encourage concrete pilots and use cases. This helps to turn AI concepts into practical value.
  4. Reform existing public education.Explore opportunities to establish an AI education voucher or an education account which would stimulate functioning adult education markets. Increase the amount of web-based training courses and open university courses for all. Integrate AI education also with vocational school curriculums.
