15 Big Data Problems You Need to Solve

Specifically, you will need to place big data staff in management roles in every department that uses that data. Organizational inertia can be individual and collective, which, in turn, can be divided into system resistance and resistance from specific groups. Therefore, it’s most convenient to consider the causes of resistance on the example of these three types of resistance, since each of them has its own specifics and characteristics.

In this subsection, we introduce several first-order optimization algorithms for solving the penalized quasi-likelihood estimators in (4.2). For most loss functions ℓn( ⋅ ), this optimization problem has no closed-form solution. To access or manipulate a data file, a client contacts the NameNode and retrieves a list of locations for the blocks that comprise the file. These locations identify the DataNodes which hold each block. Clients then read file data directly from the DataNode servers, possibly in parallel. The NameNode is not directly involved in this bulk data transfer, keeping its working load to a minimum.

Challenges of Big Data Analysis

The lack of understanding of how to work with big data opens our list of data challenges. When companies start migrating to digital products that use big data, their employees may not be ready to work with such advanced solutions. As a result, implementation with untrained personnel can cause significant slowdowns in work processes, disruptions in familiar workflows, and numerous errors. Until your employees realize the full benefits of innovation and learn how to use them, there may be a decrease in productivity.

Again, with the high volatility of data, the managers must be proactive to secure the system and address any security threats while scaling the system to accommodate the growing volume of data. Thus, to avoid the time-consuming and inefficient procedure, not forgetting the high risk of inaccuracy, it’s essential to use analytics tools to collect, manage, and analyze the data in real time. Data analytics help businesses make better decisions and become more efficient, besides gaining a competitive advantage.

Big data has created many new big data analytics challenges knowledge management and data integration. As a result, many companies need to catch up and modernize their systems to use their data effectively, as the bulk of yesterday’s tools and technologies are outdated and ineffective. When it comes to using the latest technologies and extensive data tools, you need to hire skilled and knowledgeable data professionals. Big data professionals like data scientists, data engineers, and data analysts have a good understanding of tools and know how to work with giant data sets.

The first check that you should put is at the data collection stage. Or you can use forms with drop-down fields and data validations. There’s data for every aspect of business, which more than often overwhelms employees. The plethora of data from different channels makes it difficult big data analytics for employees to drill down and determine the critical insights. And they end up analyzing the data that’s readily available and not the one that truly adds value to the business. Fritsch Virgile, Varoquaux Gaël, Thyreau Benjamin, Poline Jean-Baptiste, Thirion Bertrand.

Some of these processes and tools might have been implemented when your company was at a totally different stage, which means that they might not be a good fit for where you are now. There’s a shortage of qualified personnel in big data analytics. Without a proper strategy to ensure compliance with data protection laws — which includes protecting your data from bad actors — there’s a much higher risk of exposure. In addition, without tracking and standardizing all the channels through which you gather data, you can’t ensure that users are providing appropriate consent. Gathering data from channels that aren’t secure means that your systems are more vulnerable to external infiltration and potentially even malware. If you’re gathering data from multiple sources indiscriminately, you might be gathering fake data.

Complex Systems for Managing Data

Big data security audits should be conducted regularly to identify vulnerabilities and put the right preventive measures in place. There may also be change management challenges as employees may resist real-time reporting because the culture of daily, weekly or monthly reporting is so deeply ingrained. Multiple copies of the same records cause results to be skewed or incorrect and also drive up the costs of computation and storage. Incomplete data or data stored in inconsistent formats need to be completed and corrected in order to achieve meaningful results. Master data management and deduplication are extremely important in this context.

In the last few installments in our data analytics series, we focused primarily on the game-changing, transformative, disruptive power of Big Data analytics. The flip side to the massive potential of Big Data analytics is that many challenges come into the mix. Each data source has its own trust and certainty level, and if you combine data from sources with varying levels of credibility, the value of the entire collection of data is reduced. That’s why it’s so important to check each data source for correctness, timeliness, relevance, completeness, and ease of understanding for users.

• Of the data professionals surveyed, 66% predicted there will likely be increased dependence on software for data functions, while others expected increased data security investments (57%) and outsourcing (54%).
• An EMC survey revealed 65% of businesses predict they’ll see a talent shortage happening within the next five years.
• Moreover, the measurements and amount of data are increasing every day.
• There should be infrastructure and tools that enable data sharing between departments.
• One of the biggest challenges organizations face with Big Data is storing huge data sets correctly.
• After all, it’s impossible to glean critical insight about the future with missing or incomplete data sets.

Simply storing this voluminous amount of data is not going to be productive for your business. Be very specific with your questions, business challenges at hand, and desired outcomes. To get a FEASIBLE PROJECT, your data squad should ask business people questions over and over again and keep listening. No matter how skillful your tech talent is, your data won’t give you insights, if business users don’t know what to do about it. It’s them, regular front-line employees, – not just “geeks” – who should do analytics, develop simple visualizations, and tell stories, translating data into powerful action. Democratize your data radically to make it accessible and usable for employees with no specialized algorithm or coding knowledge.

Learning data science includes not only knowing development of algorithms, but also requires a keen understanding of other practices. This consists of a mix of metrics and KPIs that boost business growth. It can be challenging for many teams to share and collaborate on big data analytics projects due to accessibility, security, transparency, and data transfer issues. The problem is even harder for remote teams that need to collaborate over distances, leading to data quality issues. It is problematic because the challenges of big data analytics create challenges in predictive analytics as well. After all, it’s impossible to glean critical insight about the future with missing or incomplete data sets.

It’s also important to empower all employees with the tools they need to analyze and act on insights effectively. From there, you can integrate data science with the rest of the organization. Organizations initiate big data projects in order to enhance operational efficiencies, identify new strategic opportunities or accelerate the speed of business. Data analytics is a powerful method to build a competitive advantage.

The massive sample size of Big Data fundamentally challenges the traditional computing infrastructure. In many applications we need to analyze internet-scale data containing billions or even trillions of data points, which even makes a linear pass of the whole dataset unaffordable. In addition, such data could be highly dynamic and infeasible to be stored in a centralized database. The fundamental approach to store and process such data is to divide and conquer. The idea is to partition a large problem into more tractable and independent subproblems. Each subproblem is tackled in parallel by different processing units.

The left panel of Figure 3 draws the empirical distribution of the correlations between the response and individual predictors. The above discussion motivates the usage of sparse models and variable selection to overcome the effect of noise accumulation. For example, in the classification model (3.2), instead of using all the features, we could select a subset of features which attain the best signal-to-noise ratio. Such a sparse model provides more improved classification performance .

Many companies face difficulties in Big Data Analytics Implementation because they are not aware of Big Data challenges.
