The fact that there is a deep connection between the telecommunications and Big Data is very clear – the main task for telecommunications is in exchanging data. Since the amount of data has enormously increased in the modern era, the experts in telecommunication companies needed some help from the specialised experts. The need for the …
Why time series anomaly detection? Let’s say you are tracking a large number of business-related or technical KPIs (that may have seasonality and noise). It is in your interest to automatically isolate a time window for a single KPI whose behavior deviates from normal behavior (contextual anomaly – for the definition refer to this …
The client’s path, from conceiving an idea to making it a project in the bank, used to be clear, but unpredictable. It involved a potentially noticed ad or the client’s own idea, a visit to the bank counter in person and the more or less successful deal with the bank. It was very time consuming, …

In the previous article, I wrote about some introductory stuff and basic Pandas capabilities. In this part, the main focus will be on DateTime values. I am also going to introduce you to some grouping and merging possibilities in Pandas. For this purpose here is another dataset downloaded from UCI Repository, which contains date and time …
Some of the main tasks for the bankers are, among others, keeping, preserving, deriving more from less, taking the best out of what the clients deposit to them, with great confidence and trust. Almost the same definition could be applied to the Data Scientists dealing with the big data. They also deal with keeping, preserving, …
A man is defined in numerous scientific ways, but one definition seems unchanged since the beginning of time. The man is the creature that communicates – from the first attempt to speak, till the last tale told to grandchildren. “The telecommunications are defined as the exchange of the information between the source and the destination, …
In every business, the ultimate dream is the one about the magic success formula. The search for ingredients is very extensive, but they often live next door. So now the greater „magic” becomes the question of using, understanding and connecting those dots. That „magic” even has a name. „Data Science is actually the applied science …
The problem of anomaly detection is a very challenging problem often faced in data analysis. Whether it is about clustering, classification or some other machine learning problem, it is of great importance to identify anomalies and handle them in some way, in order to achieve optimal model performances. Furthermore, anomalies could often influence the analysis …
If you ever decide to become someone who is into big data, surely you can do it without having a clue about pandas.
