Анализ и обработка данных Jobs

Data science, which should not be mistaken for information science, is a field of study that uses scientific processes, methods, systems, and algorithms to extract insights and knowledge from various forms of data, be it structured or unstructured. It is similar to data mining and is a conception to unify machine learning, data analysis, statistics, and their related methods so as to analyze and understand the actual facts about data. Data science employs theories and techniques taken from many disciplines such as computer science, information science, statistics, and mathematics.

In a nutshell, data science can be said to be a multidisciplinary blend of algorithm development, data inference, and technology in a way to find solution to analytically complex problems. Data science is useful to anyone who wants to be a data miner.

    1. The original series is broken into a number of distinct sub-series using MODDWT (sometimes referred to as wavelets). 2. Each sub-series in the hybrid MODWT-RNN models is projected separately using RNN. 3. The predicted sub-series are once again blended to obtain the final forecast value. 4. To calculate performance/error measures, the final prediction value (obtained in the previous phase) is compared to the original series. 5. Using MAPE, MAE, RMSE, and MDA to evaluate the effectiveness of the models provided, Arima and RNN-LSTM are utilized to compare MODWT-ability RNN's for prediction.

    What I am looking for is to identify companies that have taken (2) loans, one in both 2020 and 2021. I am further looking to sort the data by at least NAICS code (industry) (column AM) and State (column M) I want to be able to visualize and sort the data by who was most impacted, and that will be determined by the amount of jobs lost / gained 2021 vs 2020. We can discuss further visualization (I need your guidance) but this is a minimum. We know if they have taken (2) loans if they have the same company name in 2021 however if the company only shows up once, it is 2020 so they've taken (1) loan and are not of interest to us. The total data set is under a million records.

    Hi, I have a script in Python to do some image processing using the scikit learn library (graycomatrix, graycoprops) saving the output in a .npy file. The thing works, but the problem is that it is terribly slow since it is running a long iteration. I thought about doing some multiprocessing (or using something like Dash) but I have encountered some difficulties that I have no time to resolve (e.g. doing multiprocessing in a Jupiter Notebook, multiprocessing with multiple inputs, Windows 10/11). So, I was hoping that on my base of my code, you could develop the use of multiprocessing to speed up the processing time - or whatever other (simpler?) option may be feasible to achieve the same aim. Hopefully written in the simplest manner or with comments everywhere (for me to understand what&#...
