The main challenges and key issues in data mining
IoT-connected devices generate complex data types, including sensor data, radio frequency identification data, two-dimensional code, video data, and image data. This diverse nature presents a number of challenges for data mining in IoT. According to the research, apart from the choice of the suitable algorithms, environment, and providing privacy and data security, and interoperability, there are some more pain points to deal with.
Here is the list of challenges associated with the application of data mining in IoT:

Data mining in practice – main techniques, methods and algorithms
Fundamentally, data mining is based on three major technical notions – statistics( mathematical algorithms), artificial intelligence, and machine learning.
IoT data can be:
– multimodal and heterogeneous;
– noisy and incomplete;
– unbalanced and biased;
– dependent on time and location;
– dynamic, different data quality;
– almost always require real-time analysis.
IoT data is aggregated from various resources, which can be noisy and heterogeneous. In the process of extraction of useful information, the data can be characterized as being uncertain and incomplete in the initial stages. Using IoT data mining helps solve two important tasks – defining the regular links between the data elements and using them to solve prediction problems.
Data mining involves analysis of tremendous volumes of diverse data sets with the goal of obtaining valuable knowledge. Analyzing data generated by IoT in data mining processes are broken up into multiple stages, as follows:
Data mining models and algorithms
The IoT-powered connections can vary from being small-scale to large-scale, having various capabilities and limitations. Raw data being generated from these connections also has various characteristics. The ability to make devices respond to users’ actions requires data mining. The usage of raw data generated by IoT in data mining algorithms does not provide the desired outcomes. It is necessary to choose the best DM (Data Mining) methods and algorithms to add more value to one’s business and make devices more personalized for every user.
The multi-layered data mining model
This model is divided into four layers: data collection, data management, event management, and data processing service.
- The data collection layer adopts devices to collect the smart data. Different stages require different data collection strategies. This layer solves several problems, including repeated or wrong data reading, data filtering, and communication.
- The data management layer operates the centralized distributed database or warehouse. Here, the data identification, abstraction, and compression take place. All these insights are saved in the corresponding database or warehouse. This layer connects smart objects with each other.
- The event management layer is used to analyze IoT events. Primitive and complex events are filtered, or events that concern the user are obtained.
- Data mining service is based on event management and data processing. Classification, forecasting, clustering, patterns mining, and association analysis services are provided for apps at this layer.
Mass data of IoT is stored in different places. It creates a challenge for centralized data mining architecture. Moreover, large-scale data generated by IoT in data mining should be processed in real-time. The security and privacy issues are also solved by striding the data in various places. Thus, a distributed model presupposes sending the data to the distributed nodes, and then, after pre-processing, data is sent to the central receiver. This layer allows splitting problems into smaller ones and eliminates the problem of high storage capacity and high-performance requirements. The global control node manages the whole system. It chooses the Medes algorithms and data set for analysis. Sub-nodes receive raw data from various storage types. Next, these local models are obtained by filtering events, complex detection, and mining data in local nodes. Then they are submitted to the global control node and aggregates together from the global model.
The grid-based data mining model
A new computer infrastructure – Grid, is able to implement high-performance and large-scale apps. Various computing, data, and device resources can be accessed and used conveniently. IoT devices serve as a kind of resource for Grid computing and thus the same data mining services that Grid uses, can be applicable in IoT.
Data mining model for IoT
This model receives data from context-awareness of individuals, smart connections, or environments. Trusted control plane ensures the credibility and controllability of data transmission. Data mining tools and algorithms allow users to submit acquired knowledge to various types of apps, such as logistics, smart transportation medicine, etc.

Application of DM algorithms for IoT data
To choose the right algorithms for data mining techniques for IoT, one needs to define the task and aim of the analysis. Here are some basic algorithms used for data mining in IoT:
Classification – this technique enables you to assign items into distributed categories. There are two categories that are most widely used in IoT – supervised and unsupervised learning. Classification allows to assume prior knowledge and guides the partitioning process, building the set of classified clusters representing the possible distribution process. This algorithm allows us to solve the challenge of uncertain and incomplete IoT data. Classification presupposes a variety of methods, including decision tree learning, naїve Bayes classifier, k-nearest neighbor classifier, classification with neural network and regression methods such as linear regression and logistic regression, etc.
Clustering – the technique is aimed at identifying similar patterns in the input data. The important parameter here is to determine the similarities between the individual clustered objects. The main categories of clustering algorithms include Partitioning-based clustering; Hierarchical clustering; Grid-based clustering; and Density-based (DB) clustering algorithms. Such algorithms assist in:
- high-dimensional data processing;
- finding the clusters of the same size and density to uncover correlations between the functions to facilitate the decision-making;
- provides interpretable results.
Frequent pattern mining – the technique presupposes tracing of frequently repeatable patterns to extract valuable data insights. The ASIC prerequisites include:
- Determining the significant parameters;
- Making sure that the model is compact;
- Adaptability of the model for the effective analysis of the latest relevant info and extraction of relevant data patterns.
Association analysis – in this method one looks at and chooses interesting patterns that satisfy certain existing needs. However, the patterns chosen should be informative enough for further analysis. Association analysis is to be applied with unknown patterns. It identifies the association with input and output data, identifies the factor for qualitative separation of variables into classes and describes relationships between these events. This method allows us to generate a huge number of association rules. It is necessary to focus on the most interesting ones.
Mining of massive data sets (CRISP DM methodology)
CRISP-DM (Cross Industry Standard Process for Data Mining) is an interdisciplinary methodology for dealing with the analysis of massive IoT data sets. It uses six steps – understanding of the business, understanding of data, data preparation, modeling, evaluation and deployment.
Map reduce – For the parallelization, scalability, load balancing, and fault-tolerance – there is MapReduce, which is widely used in cloud platforms for query processing for IoT data analysis.
Choice of the Data mining techniques for IoT data depends on the tasks of the data and the type of data we deal with. Choice of the right algorithms allows to clean the data, convert it into the needed formatting, and reduce the massive data sets. It helps develop, control and monitor the IoT-based application in different areas.
