Forecasting Digital Asset Return: An Application of Machine Learning Model
International Journal of Finance &Economics, EarlyView.ABSTRACT In this study, we aim to identify the machine learning model that can overcome the limitations of traditional statistical modelling techniques in forecasting Bitcoin prices. Also, we outline the necessary conditions that make the model suitable.

Hashing based Answer Selection
, 2019 Answer selection is an important subtask of question answering (QA), where deep models usually achieve better performance. Most deep models adopt question-answer interaction mechanisms, such as attention, to get vector representations for answers.

A Formula That Generates Hash Collisions [PDF]
arXiv, 2018 We present an explicit formula that produces hash collisions for the Merkle-Damg{\aa}rd construction. The formula works for arbitrary choice of message block and irrespective of the standardized constants used in hash functions, although some padding schemes may cause the formula to fail.

GPERF : a perfect hash function generator [PDF]
, 1992 gperf is a widely available perfect hash function generator written in C++. It automates a common system software operation: keyword recognition. gperf translates an n element user-specified keyword list keyfile into source code containing a k element ...

Arithmetic Progression Hypergraphs: Examining the Second Moment Method [PDF]
arXiv, 2017 In many data structure settings, it has been shown that using "double hashing" in place of standard hashing, by which we mean choosing multiple hash values according to an arithmetic progression instead of choosing each hash value independently, has asymptotically negligible difference in performance.

Key Considerations on CITE‐Seq for Single‐Cell Multiomics
PROTEOMICS, EarlyView.ABSTRACT CITE‐Seq (Cellular Indexing of Transcriptomes and Epitopes by Sequencing) is an advanced single‐cell sequencing method to profile both gene expression and protein abundance simultaneously in individual cells using single‐cell mRNA sequencing techniques alongside antibody‐derived tags (ADTs), for protein detection.

Fast and Powerful Hashing using Tabulation [PDF]
arXiv, 2015 Randomized algorithms are often enjoyed for their simplicity, but the hash functions employed to yield the desired probabilistic guarantees are often too complicated to be practical. Here we survey recent results on how simple hashing schemes based on tabulation provide unexpectedly strong guarantees.

PLANTS, PEOPLE, PLANET, EarlyView.Rice is a critical crop for the delivery of calories and essential micronutrients to the human diet. Biofortification of rice with zinc (Zn) and iron (Fe) aims to combat the health issues associated with “hidden hunger”. Arbuscular mycorrhizal (AM) fungi have been explored for their potential to enhance Zn and Fe uptake in rice products.

Practical Evaluation of Lempel-Ziv-78 and Lempel-Ziv-Welch Tries
, 2017 We present the first thorough practical study of the Lempel-Ziv-78 and the Lempel-Ziv-Welch computation based on trie data structures. With a careful selection of trie representations we can beat well-tuned popular trie data structures like Judy, m ...
