Based on theoretical analysis, this paper constructs a short-term stock selection strategy based on machine learning. The sample set is constructed based on the closing price trend of individual stocks in the last 20 trading days, and the machine learning algorithms GBDT and GBRank are used for training, and machine learning is used to automatically perform patternrecognition on the processing capabilities of high-dimensional nonlinear data. When forecasting, the former will rank stocks with higher rising probability in the next 3 trading days, and the latter will rank stocks with greater gains in the nest 3 trading days. The stock selection strategy swaps positions every 3 trading days, and each time the top 10 stocks given by the equal-weight buying algorithm are used to construct an investment portfolio. The experimental results show that the short-term quantitative stock selection strategy based on the GBDT algorithm can outperform the market combination, namely the Shanghai and Shenzhen 300 Index, and has certain practicability.

Cancer subtypes identification can facilitate the subtype-targeted treatments for different cancers. The heterogeneous nature of the disease involves activation of several pathways, significantly affecting the patients' survival and displays distinctive efficacy towards different drugs. Therefore, identification of cancer subtypes using genomic level data is critical. Over the years, several computational methods have been designed for multi-omics data integration and clustering. These methods mainly follow three algorithmic approaches: early, late, or intermediate integration of multi-omics data. Some of them perform clustering on concatenated data, other performs clustering on integrated similarities, whereas other, performs clustering on new representations. In this study, a deep learning framework of the Autoencoder is designed to obtain a low-dimensional representation of the early integrated multi-omics dataset. Spectral clustering is performed on the bottleneck layer of the Autoencoder to predict patients' clusters (cancer subtypes). The Performance of the proposed Autoencoder-assisted workflow is demonstrated on three different cancer data sets taken from The Cancer Genome Atlas database. The performance is also compared with other popular early, late, and intermediate data integration methods. Furthermore, to establish the biological relevance of the identified clusters, a detailed biological analysis of the clusters obtained from the Glioblastoma multiforme dataset (GBM) is also presented.
The bone symmetry and motion locality are two important priors for 3D human pose estimation. For bone symmetry, symmetric bones typically have equal length and higher motion correlation. In terms of motion locality, t...

Research in Artificial intelligence (AI)-based medical computer vision algorithms bear promises to improve disease screening, diagnosis, and subsequently patient care. However, these algorithms are highly impacted by the characteristics of the underlying data. In this work, we discuss various data characteristics, namely Volume, Veracity, Validity, Variety, and Velocity, that impact the design, reliability, and evolution of machine learning in medical computer vision. Further, we discuss each characteristic and the recent works conducted in our research lab that informed our understanding of the impact of these characteristics on the design of medical decision-making algorithms and outcome reliability.
