• Abstract: In this paper we conduct a longitudinal analysis of the structure of labour markets in the US over 7 decades of technological, economic and policy change. We make use of network science, natural language processing and machine learning to uncover structural changes in the labour market over time. We find a steady rate of both disappearance of jobs and a shift in the required work tasks, despite much technological and economic change over this time period. Machine learning is used to classify jobs as being predominantly cognitive or physical based on the textual description of the workplace tasks. We also measure increasing polarisation between these two classes of jobs, linked by the similarity of tasks, over time that could constrain workers wishing to move to different jobs.

The parameters for the academic perspective are discovered using 35,000 article abstracts from the Web of Science for the period 1958-2022. A complete machine learning software tool is developed for data-driven parameter discovery.

  Rapid technological innovation threatens to leave much of the global workforce behind. Governments and markets must find ways to quicken the rate at which the supply of skills reacts to changes in demand. This paper presents a pipeline which makes one-shot multi-step forecasts into the future using a decade of monthly skill demand observations.

• Low-skilled Occupations Face the Highest Upskilling Pressure [0.0]
  We examine how job contents evolve as new technologies substitute for tasks, shifting required skills rather than eliminating entire jobs. We find that re-skilling pressure is greatest for low-skilled occupations when accounting for distance between skills. Jobs from large employers and markets experienced less change relative to small employers and markets, and non-white workers in low-skilled jobs are most demographically vulnerable.

  Study of understanding dictates what does the world "mean" to a robot. With humans and robots increasingly operating in the same world, the prospects of human-robot interaction also bring semantics into the picture. Driven by need, as well as by enablers like increasing availability of training data and computational resources, semantics is a rapidly growing research area in robotics.

  We propose to solve multi-task problems through learning structured policies from human demonstrations. Our structured policy is inspired by RMPflow, a framework for combining subtask policies on different spaces. We derive an end-to-end learning objective function that is suitable for the multi-task problem.

  Job Title Benchmarking (JTB) aims at matching job titles with similar expertise levels across various companies.

We reformulate the JTB as the task of link prediction over the Job-Graph that matched job titles should have links.

• Modeling Long-horizon Tasks as Sequential Interaction Landscapes [75.5824586200507]
  We present a deep learning network that learns dependencies and transitions across subtasks solely from a set of demonstration videos. We show that these symbols can be learned and predicted directly from image observations. We evaluate our framework on two long horizon tasks: (1) block stacking of puzzle pieces being executed by humans, and (2) a robot manipulation task involving pick and place of objects and sliding a cabinet door with a 7-DoF robot arm.
