Question: How to build a machine learning method that can continuously gain structured visual knowledge by learning structured facts? Our goal in this paper is to address this question by proposing a problem setting, where training data comes as structured facts in images with different types including (1) objects(e.g., <boy>), (2) attributes (e.g., <boy,tall>), (3) actions (e.g., <boy, playing>), (4) interactions (e.g., <boy, riding, a horse >). Each structured fact has a semantic language view (e.g., < boy, playing>) and a visual view (an image with this fact). A human is able to efficiently gain visual knowledge by learning facts in a never ending process, and as we believe in a structured way (e.g., understanding “playing” is the action part of < boy, playing>, and hence can generalize to recognize <girl, playing > if just learn <girl> additionally). Inspired by human visual perception, we propose a model that is (1) able to learn a representation, we name as wild-card, which covers different types of structured facts, (2) could flexibly get fed with structured fact language-visual view pairs in a never ending way to gain more structured knowledge, (3) could generalize to unseen facts, and (4) allows retrieval of both the fact language view given the visual view (i.e., image) and vice versa. We also propose a novel method to generate hundreds of thousands of structured fact pairs from image caption data, which are necessary to train our model and can be useful for other applications.

Question: Multi-instance multi-label (MIML) learning is a challenging problem in many aspects. Such learning approaches might be useful for many medical diagnosis applications including breast cancer detection and classification. In this study subset of digiPATH dataset (whole slide digital breast cancer histopathology images) are used for training and evaluation of six state-ofthe-art MIML methods. At the end, performance comparison of these approaches are given by means of effective evaluation metrics. It is shown that MIML-kNN achieve the best performance that is %65.3 average precision, where most of other methods attain acceptable results as well.

Question: Various families of malware use domain generation algorithms (DGAs) to generate a large number of pseudo-random domain names to connect to a command and control (C2) server. In order to block DGA C2 traffic, security organizations must first discover the algorithm by reverse engineering malware samples, then generate a list of domains for a given seed. The domains are then either preregistered, sink-holed or published in a DNS blacklist. This process is not only tedious, but can be readily circumvented by malware authors. An alternative approach to stop malware from using DGAs is to intercept DNS queries on a network and predict whether domains are DGA generated. Much of the previous work in DGA detection is based on finding groupings of like domains and using their statistical properties to determine if they are DGA generated. However, these techniques are run over large time windows and cannot be used for real-time detection and prevention. In addition, many of these techniques also use contextual information such as passive DNS and aggregations of all NXDomains throughout a network. Such requirements are not only costly to integrate, they may not be possible due to real-world constraints of many systems (such as endpoint detection). An alternative to these systems is a much harder problem: detect DGA generation on a per domain basis with no information except for the domain name. Previous work to solve this harder problem exhibits poor performance and many of these systems rely heavily on manual creation of features; a time consuming process that can easily be circumvented by malware authors. This paper presents a DGA classifier that leverages long short-term memory (LSTM) networks for real-time prediction of DGAs without the need for contextual information or manually created features. In addition, the presented technique can accurately perform multiclass classification giving the ability to attribute a DGA generated domain to a specific malware family. The technique is extremely easy to implement using open source tools allowing the technique to be deployed in almost any setting. Results are significantly better than all state-of-the-art techniques, providing 0.9993 area under the receiver operating characteristic curve for binary classification and a micro-averaged F1 score of 0.9906. In other terms, the LSTM technique can provide a 90% detection rate with a 1:10000 false positive (FP) rate—a twenty times FP improvement over the next best method. Experiments in this paper are run on open datasets and code snippets are provided to reproduce the results.
