Representation Learning for Conversational Data using Discourse Mutual Information Maximization
Although many pretrained models exist for text or images, there have been
relatively fewer attempts to train representations specifically for dialog
understanding. Prior works usually relied on finetuned representations based on
generic text representation models like BERT or GPT-2. But such language
modeling pretraining objectives do not take the structural information of
conversational text into consideration. Although generative dialog models can
learn structural features too, we argue that the structure-unaware word-by-word
generation is not suitable for effective conversation modeling. We empirically
demonstrate that such representations do not perform consistently across
various dialog understanding tasks. Hence, we propose a structure-aware Mutual
Information based loss-function DMI (Discourse Mutual Information) for training
dialog-representation models, that additionally captures the inherent
uncertainty in response prediction. Extensive evaluation on nine diverse dialog
modeling tasks shows that our proposed DMI-based models outperform strong
baselines by significant margins.Comment: Preprint, 15 pages, To appear in NAACL 2022 (Main
Last Mile Delivery and Route Planning for Freight
This report analyzes anticipated list mile challenges in Indiana by using a scenario-based approach to develop forecasts of GDP growth and thus freight growth across industry clusters in Indiana counties; potential congestion implied by this growth; and a proactive plan to add capacity to alleviate the congestion. We use a quantitative approach to aggregate ramp level flows, industry cluster locations, county layout, and economic activity to develop our recommendations.
We develop forecasts through the year 2050 based on long-term planning approaches used by other states (California, Ohio, and Utah). We use data from global databases that consider different possible geo-political scenarios and regulatory choices to scale it down to county-level impact. At the same time, we track industry cluster locations within each county, ramps from interstates, and distances to travel within the counties to reach freight destinations. The result is a report that combines macro trends with micro detail to develop potential capacity bottlenecks
