Title: Deep Learning for Compliance: “Application of machine learning to online gambling data to identify money laundering”

Abstract:  Most of the current online gambling operators are using handcrafted basic rules for their anti money laundering (AML) strategy. These methods are not enough anymore for identifying complex fraudulent activities. Kindred group entered into research collaboration with City University and the main goal is to effectively use machine learning to detect money laundering. Understanding the needs of the industry and what the industry stakeholders believe was a priority. A series of interviews with various stakeholders of the gambling industry took place and the findings were published earlier this year in the form of a white paper.
The second part  of the research involved the analysis and evaluation of the gambling data that were provided by Kindred. We present how the imbalanced dataset problem was tackled, and the new experimental dataset that was created for supervised learning. The performance of  Logistic Regression (LR), Random Forest (RF) and Multilayer perceptron (MLP) was examined and compared. Our results, showed that Random Forest was the best model for predicting the normal players, while the MLP managed to detect suspicious players with the higher accuracy. Finally, the sequential relationship of the data was investigated using discrete and continuous Hidden Markov Models (HMM).

Title: Building IARA – The Intelligent Autonomous Robotic Automobile


The Intelligent Autonomous Robotic Automobile  (IARA) is one of the most advanced self-driving cars in world, figuring in eighth place according to the metric of number of interventions per 1000 miles in 2017. We start building IARA in 2009 and, since then, more than 30 students, including Ph.D., M.Sc., and undergraduates, have completed their courses working on the project. IARA is based on the precise localization paradigm where the self-driving car must have a detailed map of the environment to operate autonomously. In this talk, we will present some of the history behind the 10 years of research that led to the current status of development of IARA and will describe how some of its main software modules work, including the modules responsible for mapping, localization and autonomous navigation.
A demonstration video can be found here.

Title: Deterministic Microgrid Optimal Operation

Abstract: With the inclusion of renewable energy into power systems, traditional power system face new challenges. Due to their inherent fluctuations and variability,  the introduction of renewable energies in power systems poses new challenges in modeling uncertainty. Controlling and optimizing the operation cost by adjusting the output generation of renewable energy resources make power systems operation more reliable and secure. In this work, we aim to solve one optimal microgrid management problem in deterministic and probabilistic framework. This microgrid is connected to the utility and comprises of different renewable energy generators such as photovoltaic (PV), wind generators, batteries, hydroelectric plants, and microturbine.
The objective is to minimize the cost of generation and the voltage deviation from the reference.
The optimization problem is nonlinear since the AC load flow which is a constraint in the optimization problem is nonlinear. we linearize AC load flow in the first step. Secondly, we model the problem in a deterministic framework without considering the impact of uncertainties on power system. The other physical constraints which are taken into account in this work are the equality constraint of load generation balance, output power limitation and voltage limitation. Finally, we will model the nonlinear problem in probabilistic framework to see how uncertainties can affect the system. The first two steps have been done before transferring to PhD and the final step will be done in the next following two years.

Research Visit

News, Seminar.

Luciano Serafini (FBK, Trento, Italy) and Michael Spranger (Sony CSL, Tokyo, Japan) visited City’s Research Centre for Machine Learning during the week of 10 Dec 2018. The main focus of the visit was to continue research collaborations on Logic Tensor Networks. LTNs are a deep learning system implemented in Tensorflow, capable of reasoning with first-order many-valued logic. For more information, please check the webpage of the IJCAI’2018 tutorial on LTNs:

Title: Reading and Reasoning with Neural Program Interpreters 

Abstract: We are getting better at teaching end-to-end neural models how to answer questions about content in natural language text. However, progress has been mostly restricted to extracting answers that are directly stated in the text. In this talk, I will present our work towards teaching machines not only to read but also to reason with what was read and to do this in an interpretable and controlled fashion. Our main hypothesis is that this can be achieved by the development of neural abstract machines that follow the blueprint of program interpreters for real-world programming languages. We test this idea using two languages: an imperative (Forth) and a declarative (Prolog/Datalog) one. In both cases, we implement differentiable interpreters that can be used for learning reasoning patterns. Crucially, because they are based on interpretable host languages, the interpreters also allow users to easily inject prior knowledge and inspect the learnt patterns. Moreover, on tasks such as math word problems and relational reasoning, our approach compares favourably to state-of-the-art methods.


Sebastian Riedel is a reader in Natural Language Processing and Machine Learning at the University College London (UCL), where he is leading the Machine Reading lab. He is also the head of research at Bloomsbury AI and an Allen Distinguished Investigator.

Ing) and Edinburgh (MSc., PhD), and worked at the University of Massachusetts Amherst and Tokyo University before joining UCL.
