Carissimi N, Beyan C, Murino V. A multi-view learning approach to deception detection. Proc—13th IEEE Int Conf Autom Face Gesture Recognition, FG 2018. 2018;599–606. The institutional misogyny and racism of the undercover units being investigated by the UCPI (set up in 2015) is part of a far bigger, national picture. With its investigations concentrating on two “elite” units in special branch, the UCPI’s focus is on the officers who spied on people involved in political protest and campaigning. But Mary’s case shifts the narrative. If it happened to Mary, it could happen to anyone. How many more women are there like her? Women who are manipulated, deceived, violated and then silenced by the authorities? Women like you, your sister, or your friend perhaps? Helen, Lisa, Alison, Belinda and Naomi tell our version of what’s now known as the “spycops scandal”. However, the datasets and experiment setups are too diverse to be compared. Therefore, a direct benchmark of the studies’ performances is not reasonable. We include them here as another feature of those studies, but we do not claim that the specific research that achieved a higher accuracy than other is better. Those performance measures do not work here as a scale of success when approaching the problem, nor do they indicate that a particular approach is better than other. They can work, at best, as a baseline for further research designed under the same conditions. To the best of our knowledge, this is the first literature review that scrutinizes the application of Machine Learning for deception detection. Trends, gaps, difficulties, results, and opportunities are highlighted to stimulate further studies and new developments in the area.

Superior lie-catchers seem to acquire their ability from a personal desire to perform better on their job, no matter what it is [ 5]. It is like any other professional skill or talent, improved through effort, dedication, personal interest, technical knowledge, and training. Thus, such highly skilled lie-catchers result from intense dedication, which is a motivating factor for further research on deception detection. It is reasonable to believe that those levels of accuracy can be approximated or even replicated by a Machine Learning classifier given the correct cues are processed and interpreted.

Only MLP and MLN are not Deep Learning models, and together they appear in 15 articles (44.11%). All other flavors of Neural Networks (19 papers, 55.89%) use Deep Learning in several variations, revealing a trend of choice. We consider the trend natural given the level of excellence Deep Learning models have shown in the last decade. One of their virtues is that feature selection is automatic. All those Jupyter Lab Notebooks can be found at GitHub. Here we present only the discussion of our findings, as we consider that our greatest contribution. Throughout the time they were together, Dines was married to someone else; his parents were alive and well. When his deployment was over, he left a note on the kitchen table telling her that he needed some space and abruptly disappeared. Three studies experimented on psychological features. One consumed NEO-FFI (Neuroticism-Extraversion-Openness Five-Factor Inventory) scores along with demographic and vocal cues [ 105]. NEO-FFI is a five-factor personality model based on an empirically developed taxonomy of personality traits. This model measures five personality components: Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The other study presents a monomodal approach (see section 3.3 in S6 File) based on emotional cues [ 48]. It exploits a mobile app that can monitor the emotion level by noticing the user’s shaking hands. This study reported 0.84 accuracy from a Random Forest classifier but did not measure the specific emotions related to deception.

This is the first chapter in the Dark Deception story. Investigate and survive the first maze. Be careful though. You are not alone. There are monsters in there and they are looking for you. You will face your fears. The question is - what are you afraid of? Our main goal is to comprehensively understand of the state of research regarding deception detection with Machine Learning. To do so, we surveyed, studied, and selected a collection of 81 documents out of 648 retrieved from four scientific databases. We report our findings in both quantitative and qualitative fashions. Srinivasu PN, Sivasai JG, Ijaz MF, Bhoi AK, Kim W, Kang JJ. Classification of Skin Disease Using Deep Learning Newural Networks with MobileNet V2 LSTM. Sensors (Switzerland). 2021;21:1–27. As our contribution to the field, we present a discussion that unfolds in several themes (or dimensions) we consider suitable. Those themes were not chosen. Rather, they arise from the selected documents and represent a general summary of all the efforts analyzed. Those themes are findings themselves. They outline the main topics present in the selected studies regarding the theoretical foundations of deception detection. Authors attempted these approaches to answer to the deception detection problem. All the metadata was extracted directly from the selected corpus and no value was, by any means, inferred or interpreted. Sometimes, the total number of features was summed when the text didn’t present it, but all the primitive values were there. Such metadata describes the source of training data, training strategy, Machine Learning methods, dataset sizes, predictors exploited, cues complexity, modality cardinality, performance levels, and performance metrics.

Classification tasks rely on algorithms that assign a given class (or label) to a specific data example. Those classes are a limited number of categorical values [ 19]. So, they are not continuous values (while features can be). Ekman reports that faking an emotion may be easier (especially for professional actors), but not demonstrating strong ones is almost impossible since some facial expressions involuntarily arise [ 2]. It is said that these emotions “leak out”, betraying the deceiver. This is a strong stimulus for further research and efforts to produce labeled datasets from actual data under more diverse circumstances. More cues could be identified and related to particular settings. Fake expressions from actors could be an important addition to the datasets.

In response to the book, the Met reiterated its regret, stating: “Undercover policing has changed significantly with independent judicial oversight of all operations, and past events highlighted in this book in no way reflect modern-day undercover policing. We recognise the hurt and distress caused to the authors of this book. The actions of undercover officers who deceived these women into sexual relationships were totally unacceptable.” We aim to find out which Machine Learning techniques perform best for automatic deception detection, what kind of data they process, what is the source of that data, and what theoretical framework they have used. We also seek to understand their limitations and merits, and what remains to be explored. On 5thApril, CWJ are co-hosting a book launch of ‘Deep Deception’, hosted by Samira Ahmed where I shall join the authors of this important book to explore the dark and seedy scandal of undercover policing that impacted so profoundly on so many women’s lives.
