Information Fusion
Why should your organisation modernise its data platform?
Many organisations have been using data to derive insights and make decisions for years and even decades now. If you have worked in such an organisation or own one or more of them, you will know that gaining insights from data is not a walk in the park. When you think of it, it appears easy -- get the data, clean, structure, and load it and fire queries. Well, that works with few data sets, but imagine you need to do that on a large scale, day in day out, without much delay and expect accurate answers -- it gets complicated. Hence, organisations have been spending a huge amount of resources on building enterprise-wide ETL frameworks to extract, transform and load the data into data warehouses capable of storing them at a large scale in a structured format (and often pre-aggregated).

Establish data intelligence at first sight: Data Inventory is a new cloud-based app designed for self-service that automatically inventories and quality checks data to establish data intelligence quickly and easily. It unlocks data silos and fosters collaboration and reuse so that data professionals don't need to repeatedly build the same datasets. Boost data intelligence at speed: With new intelligent data preparation capabilities, Talend Pipeline Designer, a modern, cloud-based solution for building and deploying data pipelines, now provides an in-flight data quality feature that eliminates quality problems before the data is consumed or replicated. Additionally, no coding or complex transformations are required, which will help citizen integrators increase development and maintain productivity. Empower everyone with data intelligence at scale: Intelligent data quality with augmented intelligence uses machine learning to compare data matching so customers can empower everyone in the organization with data intelligence.

Turn your raw data into a machine learning model without Python or SQL Google Cloud Blog
Notice that the column we'd like to predict, AVERAGERESPONSETIME, is in a mm:ss format. We'll need to change that into a numeric format, such as seconds. This is an example of a processing step on the raw data that is required to build a model. We'll be working with four products in this post: The first step is to upload the CSV file into a Cloud Storage bucket so it can be used in the pipeline. Next, you'll want to create an instance of Cloud Data Fusion.
Multimodal Categorization of Crisis Events in Social Media
Abavisani, Mahdi, Wu, Liwei, Hu, Shengli, Tetreault, Joel, Jaimes, Alejandro
Recent developments in image classification and natural language processing, coupled with the rapid growth in social media usage, have enabled fundamental advances in detecting breaking events around the world in real-time. Emergency response is one such area that stands to gain from these advances. By processing billions of texts and images a minute, events can be automatically detected to enable emergency response workers to better assess rapidly evolving situations and deploy resources accordingly. To date, most event detection techniques in this area have focused on image-only or text-only approaches, limiting detection performance and impacting the quality of information delivered to crisis response teams. In this paper, we present a new multimodal fusion method that leverages both images and texts as input. In particular, we introduce a cross-attention module that can filter uninformative and misleading components from weak modalities on a sample by sample basis. In addition, we employ a multimodal graph-based approach to stochastically transition between embeddings of different multimodal pairs during training to better regularize the learning process as well as dealing with limited training data by constructing new matched pairs from different samples. We show that our method outperforms the unimodal approaches and strong multimodal baselines by a large margin on three crisis-related tasks.
Knowledge Fusion and Semantic Knowledge Ranking for Open Domain Question Answering
Banerjee, Pratyay, Baral, Chitta
Open Domain Question Answering requires systems to retrieve external knowledge and perform multi-hop reasoning by composing knowledge spread over multiple sentences. In the recently introduced open domain question answering challenge datasets, QASC and OpenBookQA, we need to perform retrieval of facts and compose facts to correctly answer questions. In our work, we learn a semantic knowledge ranking model to re-rank knowledge retrieved through Lucene based information retrieval systems. We further propose a ``knowledge fusion model'' which leverages knowledge in BERT-based language models with externally retrieved knowledge and improves the knowledge understanding of the BERT-based language models. On both OpenBookQA and QASC datasets, the knowledge fusion model with semantically re-ranked knowledge outperforms previous attempts.
A new approach for generation of generalized basic probability assignment in the evidence theory
Wu, Dongdong, Liu, Zijing, Tang, Yongchuan
The process of information fusion needs to deal with a large number of uncertain information with multi-source, heterogeneity, inaccuracy, unreliability, and incompleteness. In practical engineering applications, Dempster-Shafer evidence theory is widely used in multi-source information fusion owing to its effectiveness in data fusion. Information sources have an important impact on multi-source information fusion in an environment of complex, unstable, uncertain, and incomplete characteristics. To address multi-source information fusion problem, this paper considers the situation of uncertain information modeling from the closed world to the open world assumption and studies the generation of basic probability assignment (BPA) with incomplete information. In this paper, a new method is proposed to generate generalized basic probability assignment (GBPA) based on the triangular fuzzy number model under the open world assumption. The proposed method can not only be used in different complex environments simply and flexibly, but also have less information loss in information processing. Finally, a series of comprehensive experiments basing on the UCI data sets are used to verify the rationality and superiority of the proposed method.

Deep transformation models: Tackling complex regression problems with neural network based transformation models
Sick, Beate, Hothorn, Torsten, Dรผrr, Oliver
We present a deep transformation model for probabilistic regression. Deep learning is known for outstandingly accurate predictions on complex data but in regression tasks, it is predominantly used to just predict a single number. This ignores the non-deterministic character of most tasks. Especially if crucial decisions are based on the predictions, like in medical applications, it is essential to quantify the prediction uncertainty. The presented deep learning transformation model estimates the whole conditional probability distribution, which is the most thorough way to capture uncertainty about the outcome. We combine ideas from a statistical transformation model (most likely transformation) with recent transformation models from deep learning (normalizing flows) to predict complex outcome distributions. The core of the method is a parameterized transformation function which can be trained with the usual maximum likelihood framework using gradient descent. The method can be combined with existing deep learning architectures. For small machine learning benchmark datasets, we report state of the art performance for most dataset and partly even outperform it. Our method works for complex input data, which we demonstrate by employing a CNN architecture on image data.
