To help simplify complex tasks, Diet passes legislation allowing online administrative procedures

The Japan Times

The Diet on Friday enacted legislation that enables online administrative procedures in order to enhance residents' convenience by simplifying complex procedures related to events such as changes of address, death and property inheritance. The bill was approved at a plenary meeting of the House of Councilors, the upper chamber of the Diet, by a majority vote with support from ruling and opposition party lawmakers. It cleared the House of Representatives, the lower chamber, earlier this month. The government is set to draw up a relevant program by yearend, and online administrative procedures will become available in stages as soon as a necessary system is ready. At a news conference the same day, Chief Cabinet Secretary Yoshihide Suga said, "We hope to realize more efficient and affluent communities by making the most of digital technologies and further pushing forward with the digitalization of the whole society."


Online Cake Cutting (published version)

arXiv.org Artificial Intelligence

We propose an online form of the cake cutting problem. This models situations where agents arrive and depart during the process of dividing a resource. We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some fairness properties that online cake cutting procedures can possess like online forms of proportionality and envy-freeness. We also consider the impact of collusion between agents. Finally, we study theoretically and empirically the competitive ratio of these online cake cutting procedures. Based on its resistance to collusion, and its good performance in practice, our results favour the online version of the cut-and-choose procedure over the online version of the moving knife procedure.


Smoothed Bernstein Online Aggregation for Day-Ahead Electricity Demand Forecasting

arXiv.org Machine Learning

We present a winning method of the IEEE DataPort Competition on Day-Ahead Electricity Demand Forecasting: Post-COVID Paradigm. The day-ahead load forecasting approach is based on online forecast combination of multiple point prediction models. It contains four steps: i) data cleaning and preprocessing, ii) a holiday adjustment procedure, iii) training of individual forecasting models, iv) forecast combination by smoothed Bernstein Online Aggregation (BOA). The approach is flexible and can quickly adopt to new energy system situations as they occurred during and after COVID-19 shutdowns. The pool of individual prediction models ranges from rather simple time series models to sophisticated models like generalized additive models (GAMs) and high-dimensional linear models estimated by lasso. They incorporate autoregressive, calendar and weather effects efficiently. All steps contain novel concepts that contribute to the excellent forecasting performance of the proposed method. This holds particularly for the holiday adjustment procedure and the fully adaptive smoothed BOA approach.


Japan's local governments advance hanko-free procedures

The Japan Times

Local governments are accelerating efforts to scrap the use of hanko seals in line with Prime Minister Yoshihide Suga's focus on digitalizing administrative procedures. A number of local heads have expressed their backing for the initiative by the Suga administration, which began about a month ago. Meanwhile, leaders of communities hosting hanko manufacturers are increasingly frustrated at the trend, saying that seals should not be viewed as a symbolic obstacle to digitalization. As of the end of September, the municipal government of Fukuoka made the use of hanko unnecessary for some 3,800 types of administrative procedure documents. With Mayor Soichiro Takashima spearheading reform efforts, Fukuoka already processed 73.7 percent of its administrative work online as of the end of March.
