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.

    At Pinwheel, we want to build natural language processing (NLP) models that can detect potentially concerning situations or encounters (such as violence, bullying, and suicidal ideation) from a large corpus of text messages. The goal is to proactively notify parents of these incidents and allow them to take remedial action in a timely manner. We are currently building an MVP model focusing on violence, but we want to improve the performance of this model and extend it to other situations (such as bullying and suicidal ideation). There are several challenges involved in this project, including the variability of language, the multi- author nature of the text message data, and the need to deal with class imbalance in the data. The practicum students will work on addressing these challenges ...

    - I have a number of PDFs that I want to use to train an AI model. You will: 1. Write specific and easy to follow scripts for each step of the process so that I can replicate at another date. 2. Carry out Preprocessing: Clean and preprocess the text data, removing any irrelevant information such as HTML tags, special characters, duplicates, and handle missing values. 3. Tokenize the text into smaller units, such as words or subwords, and convert the text into numerical representations, such as word embeddings, using techniques like stemming, lemmatization, and lowercasing. 4. Carry out text tagging - Assign labels or tags to individual tokens or sequences of tokens in the text (e.g., named entity recognition, sentiment analysis, topic classification, etc.) using spaCy, NLTK, Stanford...

    Hello! I have all my school reports from when I was a child. There are 11-12 school reports in total. The first starts in year 1993 and covers the first half of my schooling. All the reports from 1993 until 1999 contain hand written text and cover from prep/foundation until year 6. The second half from 2000 until 2004 and describe my high school experience and the text is printed via a computer. I would like to run text and sentiment and sentiment analysis to unlock and discover key themes per yea over time, and each half year, each report is either covering the first or second half of an allocated year and to identify and uncover any consistent themes over time. The analysis should also identify any outlier years and the corresponding reasons why based on teacher feedback. How can I ...

    C+ algorithm to sort 2d points in a linear fashion 18 часов(-а) left
    ПОДТВЕРЖДЕН

    I need an optimized algorithm written in c++ to sort 2d points along a route. The function shall receive a pointer to a vector that contains a quantity of random points (represented by x,y float coordinates). A typical set will contain 300,000 points. It has to order these points in a way that they form a continuous line, trying to achieve the shortest line possible. Let's say that 3 different people were each holding a pen. There is a somewhat blurred route that goes from location A to location B. These people are told to draw a line along the blurred route starting near one of the locations and going towards near the other (attachment ). For every 'd' distance along the drawn lines, the coordinates of a point are saved in the vector. We do not know which coordinate belong...

    Trophy icon [Data science] Crypto currency predition 3 дней(-я) left

    Data science: Based on crypto historical data we would like to predict where is the Best moment to buy crypto or sell. We could test algoritm on for example Etherium crypto then apply it to rest of crypto curriencies. Following task can be split for steps: 1. Find where data can be retrieved(free api or other method like scrapping) We can Focus on value in each day and/or hour. 2. Create algoritm based on known data science Methods, some existing library can be used. (Like neural Networks, linear Regression etc) 3. As output we do prediction for future And Stored in database. 4. Output is later validated, calculating accuracy. 5. Accuracy should be higher than 60%, close to 100% would be perfect. I recommend to use Java for that, but if you feel better in for example Python or other lan...
