• Title: News-Driven Stock Prediction With Attention-Based Noisy Recurrent State Transition
• Authors: Xiao Liu, Heyan Huang, Yue Zhang, Changsen Yuan
• Abstract summary: We consider direct modeling of underlying stock value movement sequences over time in the news-driven stock movement prediction. A recurrent state transition model is constructed, which better captures a gradual process of stock movement continuously. We are the first to explicitly model both events and noise over a fundamental stock value state for news-driven stock movement prediction.

• Abstract: We consider direct modeling of underlying stock value movement sequences over time in the news-driven stock movement prediction. A recurrent state transition model is constructed, which better captures a gradual process of stock movement continuously by modeling the correlation between past and future price movements. By separating the effects of news and noise, a noisy random factor is also explicitly fitted based on the recurrent states. Results show that the proposed model outperforms strong baselines. Thanks to the use of attention over news events, our model is also more explainable. To our knowledge, we are the first to explicitly model both events and noise over a fundamental stock value state for news-driven stock movement prediction.

  "Score-based assessment" framework for estimating transferability of pre-trained speech models. We leverage upon two representation theories, Bayesian likelihood estimation and optimal transport, to generate rank scores for the PSM candidates. Our framework efficiently computes transferability scores without actual fine-tuning of candidate models or layers.

• The Wisdom of Crowds: Temporal Progressive Attention for Early Action Prediction [104.628661890361]
  Early action prediction deals with inferring the ongoing action from partially-observed videos, typically at the outset of the video. We propose a bottleneck-based attention model that captures the evolution of the action, through progressive sampling over fine-to-coarse scales.

  Motion is an important cue for video prediction and often utilized by separating video content into static and dynamic components. Most of the previous work utilizing motion is deterministic but there are methods that can model the inherent uncertainty of the future. In this paper, we reason about appearance and motion in the videoally by predicting the future based on the motion history.

  We propose a relational event-driven stock trend forecasting (REST) framework, which can address the shortcoming of existing methods. To remedy the first shortcoming, we propose to model the stock context and learn the effect of event information on the stocks under different contexts. To address the second shortcoming, we construct a stock graph and design a new propagation layer to propagate the effect of event information from related stocks.

  We have explored the relationship between sentiment extracted from financial news and tweets and FTSE100 movements. The sentiment captured from news headlines could be used as a signal to predict market returns; the same does not apply for volatility. We developed an accurate classifier for the prediction of market volatility in response to the arrival of new information.

  We introduce an attention-based feed-forward network that explicitly leverages the observation that human motion tends to repeat itself. In particular, we propose to extract motion attention to capture the similarity between the current motion context and the historical motion sub-sequences. Our experiments on Human3.6M, AMASS and 3DPW evidence the benefits of our approach for both periodical and non-periodical actions.

• Deep Recurrent Modelling of Stationary Bitcoin Price Formation Using the Order Flow [0.0]
  We propose a deep recurrent model based on the order flow for the stationary modelling of the high-frequency directional prices movements. We show that without any retraining, the proposed model is temporally stable even as Bitcoin trading shifts into an extremely volatile "bubble trouble" period. The significance of the result is shown by benchmarking against existing state-of-the-art models in the literature for modelling price formation using deep learning.
