Data Science 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.

    Items ordered from an e-commers website will be shipped from the store to a hub, where it is dropped off and picked up by another truck, who delivers it to the final destination The hub has two trucks coming and picking up all the available shipments (no limit in loading space). The first truck always arrives on the hour (1:00, 2:00, 3:00, … ). The second truck arrives x minutes after the hour where x is some uniform random number between 0 and 60 (1:00 + x, 2:00 +x, 3:00 + x, …). Let’s assume that a shipment is dropped off at the hub at a uniformly random time (i.e. whenever). What is the average time it will wait at the hub before getting picked up? Write a program that computes the average waiting time using a simulation.

    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.
