Video anomaly detection is becoming of increased interest as surveillance is becoming more widespread. We propose an object-centric method with memory augmentation (ObjMemAE) for video anomaly detection. Recently, object-centric approaches is seen at the top of the leaderboards, where we take the novel approach of combining an object-centric approach with memory augmentation using a long term memory bank storing prototypical objects. The memory module also allows the use of additional object-centric features. The proposed method is shown to outperform the baseline by 4.5%, with an AUC score of 98.3% on the UCSD-Ped2 dataset achieving state-of-the-art.

In its nine chapters, this book provides an overview of the state-of-the-art and best practice in several sub-fields of evaluation of text and speech systems and components. The evaluation aspects covered include speech and speaker recognition, speech synthesis, animated talking agents, part-of-speech tagging, parsing, and natural language software like machine translation, information retrieval, question answering, spoken dialogue systems, data resources, and annotation schemes. With its broad coverage and original contributions this book is unique in the field of evaluation of speech and language technology. This book is of particular relevance to advanced undergraduate students, PhD students, academic and industrial researchers, and practitioners.

When the first interaction model has been designed (cf. Section 4.1) interactive speech system development may either go through a phase of Wizard of Oz (WOZ) simulations as will be described in this chapter, or go straight to implementation (Chapter 6) following the implement-test-revise approach (Figure 3.1). Today’s research on interaction model design for advanced interactive speech systems often includes the WOZ experimental prototyping method. In WOZ a human (the wizard) simulates whole or part of the interaction model of the system to be developed, carrying out spoken interactions with users who are made to believe that they are interacting with a real system. WOZ is a relatively costly development method because: (1) the wizard needs a significant amount of training and support; (2) involving experimental subjects, WOZ experiments require careful planning and preparation and take time to run; and (3) experimental results have to be transcribed and analysed, which takes time and requires skill to benefit further system development. On the other hand, by producing data on the interaction between a (fully or partially) simulated system and its users, WOZ provides the basis for early tests of the system and its feasibility, as well as of the coverage and adequacy of requirements prior to implementation. The use of WOZ has so far been justified through the comparatively higher cost of having to revise an already implemented interactive speech system whose interaction model turned out to be seriously flawed, or of having to discard a system which users will not use. As recognition and parsing techniques continue to improve and the body of standard software grows, implement-test-revise methods are likely to gain ground in the design of advanced interactive speech systems.

Pangan merupakan barang yang pertama kali ingin dipenuhi oleh setiap individu, karena tanpa pangan manusia tidak akan dapat mernpertahankan hidupnya. Masalah pangan secara global sudah mulai dikemukakan oleh Parton Malthus tahun 1878 (Falcon dkk,1983). Di Indonesia, masalah pangan sudah timbul sejak tahun 1655 yang merupakan tahun sangat kering, sehingga Sunan Amangkurat I melarang pengiriman beras keluar daerah (Mulyono S, 1981). Di Indonesia walaupun bahan pangan utama adalah beras, namun banyak terdapat bahan pangan lain seperti jagung, gaplek, sagu, terigu dan sebagainya.
