数据科学 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.

    Description: I have an image/object recognition task which require to convert image process flow diagrams to sensible texts workflow. The objects would include arrows, connectors and figures, and there would be texts as well. Instructions: Convert the diagram into interpretable texts, taking arrows, connectors and objects into consideration. Some of the texts maybe irrelevant and can be ignored Objective: Able to interpret the diagrams. Not necessary all images need to be interpreted accurately If you are interested, please DM me and I will share with the files that require to work on. Thank you.

    Publishing social media data would raise more concerns on user privacy. To encourage data sharing and mitigate user privacy concerns, a number of anonymization and de-anonymization algorithms have been developed to help protect privacy of social media users. In this work, we propose a new adversarial attack specialized for social media data. We further provide a principled way to assess effectiveness of anonymizing different aspects of social media data. Our work sheds light on new privacy risks in social media data due to innate heterogeneity of user-generated data which require striking balance between sharing user data and protecting user privacy.

    The project will require you to perform data pre-processing that is needed for each dataset that will be used in this project. Thereafter, you will be required to build models for each of the two classifiers and optimize them for accuracy. Finally, you will experiment with different data distributions and then compare the two classifiers in terms of stability of their model accuracy.

    I am starting out in data science and machine learning be I have a few questions that will help me progress in my own projects. I want to develop model that recognises certain stock chart patterns like a triangle, bullish/bearish flag etc. What I am looking for at the moment is not someone who will deliver a complete project but I need consultancy where people can answer some of the questions I have that is why I want to pay hourly. What I am struggling with at the moment is preparing the complete dataset for machine learning. I have a collection of many samples of the chart pattern (some are attached) But I don’t know how to compile the master dataset with a large set of stocks each having a varying amount of time periods showing open, high , low, close and volume. To make sure ...

    This assignment covers linear regression and logistic regression using disciminative meth- ods. 1 The Iris Dataset The Iris flower data set () was orga- nized by Ronald Fisher in 1936. It is a commonly used dataset for introductory machine learning concepts. You will use this dataset for use with a classification AND regression task. 1.1 Preparing the Data To begin, load the data using scikit-learn. As we saw during class, the setosa samples are very clearly linearly separable given any combination of two features. However, the versicolor and virginica usually have some overlap. In order to verify the models that you will create in the following two sections, you will need to take some portion of the dataset and reserve it for testing. Randomly select 10% of the dataset, ensuring an eve...
