Leveraged grid-trading bot using CCXT/CCXT Pro library in FTX exchange

The code is designed to perform infinity grid trading strategy in FTX exchange. The basic trader named Gridtrader.py control the number of grids dynamically using the setting in JSON file. asyncGridtrader.py will do the same job asynchronously. Trader with database support, Gridtrader_with_db.py and asyncGridtrader_with_db.py, will store the transaction info in database via mysql.

A Statutory Article Retrieval Dataset in French

This repository contains the Belgian Statutory Article Retrieval Dataset (BSARD), as well as the code to reproduce the experimental results from the associated paper by A. Louis, G. Spanakis, and G. Van Dijck. Abstract. Statutory article retrieval is the task of automatically retrieving law articles relevant to a legal question. While recent advances in natural language processing have sparked considerable interest in many legal tasks, statutory article retrieval remains primarily untouched due to the scarcity of large-scale and high-quality annotated […]

Splitting Datasets With scikit-learn and train_test_split()

One of the key aspects of supervised machine learning is model evaluation and validation. When you evaluate the predictive performance of your model, it’s essential that the process be unbiased. Using train_test_split() from the data science library scikit-learn, you can split your dataset into subsets that minimize the potential for bias in your evaluation and validation process. In this course, you’ll learn: Why you need to split your dataset in supervised machine learning Which subsets of the dataset you need […]

A Two-stage Approach to Speech Bandwidth Extension

August 30, 2021 By: Ju Lin, Yun Wang, Kaustubh Kalgaonkar, Gil Keren, Didi Zhang, Christian Fuegen Abstract Algorithms for speech bandwidth extension (BWE) may work in either the time domain or the frequency domain. Time-domain methods often do not sufficiently recover the high-frequency content of speech signals; frequency-domain methods are better at recovering the spectral envelope, but have difficulty reconstructing the details of the waveform. In this paper, we propose a two-stage approach for BWE, which enjoys the advantages of […]
