  • Big data is a field that treats how to analyze data, methodically pull out information and deal with data sets that are of huge volume.

    Big Data Analytics is inspecting a large amount of data, prediction of future probabilities and trends, identification of hidden patterns, unknown correlations, analyzing better business decisions, strategic and operational, effective marketing and increased revenue. It is predicted that around 84 percent of enterprises believe those without an analytics strategy run the risk of dropping a competitive edge in the market.

     

    The best substitute for prediction accuracy is “Black-box” models followed by software quality assurance services, but it comes with less accountability than other model choices. While conclusions generated after many data manipulations make it challenging for us to simply explain how the model has arrived at specific recommendations. Predictive analytics is the use of statistical algorithms, data and machine-learning techniques to identify the most feasible future outcomes based on factual data. Therefore the “black box” model is no different from the classical models as it takes a known input, runs it through the “trained model”, and relates the data set to the known outcome in order to compute the accuracy of the model’s predictions.

     

    The stock market is non-linear in nature, making predication very complicated, challenging and uncertain action. Applying traditional methods may not safeguard the reliability of stock prediction.

    Data mining allows for useful information to be extracted from huge data and capable of predicting future trends. Organizations and corporations are using Big Data analytics to get awareness into the stock market trends to make decisions that will have a better impact on their business. With rapid changes in the stock market, investors have access to a lot of data and Big data lets these investors use the data with complicated mathematical formulas along with algorithmic trading which plays a powerful role in making online trading decisions. Businesses accumulate treasure of quantitative and qualitative data and this data can be highly valuable if analyze and interpreted in the right manner towards determining useful insights and results.

     

    A search engine searching web pages, business reports, etc based on search terms requires sophisticated algorithms and the ability to process a staggering number of requests. Search has always been about extremely large datasets and statistical analysis of those sets. Big data has made possible the development of highly capable online search engines that can handle tons of data - billions and billions of records - quickly, easily, and fast. Using many different big data techniques it is skilled in analyzing through millions of websites and petabytes of data and to give you the correct output within milliseconds. Everything in Big Data today is all about “distributed” and “sharded” which is dividing up jobs in pieces and spreading them over a cluster. When we feed query logs and click logs into Big Data, we have a statistically valid method to rate the search engine accuracy. And once we can measure search engine accuracy, we can iteratively improve it to meet business needs.
