Data Science is an inter-disciplinary field that uses scientific methods to obtain and process multiple data of interest to your business. Data science can answer to questions on complex operational, financial, R&D, customer and market matters.
Data science efforts generally encompass several common underlying services, which we’ve listed below. We customize and combine these services to meet your organization’s specific needs. Please contact us if there are additional unlisted services that you need assistance with.
Some benefits that companies can obtain from Data Science
- Detection and identification of systemic redundancy and bottlenecks
- Detection and identification of high/low cost cause-effect variables
- Detection and communication with markets of interest
- Insights on customer needs and purchasing behavior
- Insights on industrial chain risks and opportunities
- Key insights for product/service design and development
Data Science Process
This is first step of all Data Science projects. And just like the name states, it is simply the step where we obtain all available data needed from various data sources.
The way to go about Data Collection is strongly based on the problem which is to be solved. There are various ways of gathering data which includes:
- Web scraping.
- Querying databases.
- Questionnaires and surveys.
- Reading from excel sheets and other documents.
- Other crowd-sourcing methods.
Data cleaning is the process of identifying and removing (or correcting) inaccurate records from a dataset, table, or database and refers to recognizing unfinished, unreliable, inaccurate or non-relevant parts of the data and then restoring, remodelling, or removing the dirty or crude data.
Data cleaning techniques may be performed as batch processing through scripting or interactively with data cleansing tools.
After cleaning, a dataset should be uniform with other related datasets in the operation. The discrepancies identified or eliminated may have been basically caused by user entry mistakes, by corruption in storage or transmission, or by various data dictionary descriptions of similar items in various stores.
This involves the massaging and manipulation of data to get the necessary insights, trends and patterns. This process covers Data Exploration and Model Development.
Data Exploration is used to understand, summarize and analyze the contents of a dataset, usually to find answers to the existing problem or to prepare for model development.
This is where Exploratory Data Analysis (EDA) comes in. The data at this step is critically studied, insights deduced, outliers taken care of and new features engineered if there is a need to.
Model Development involves the provision of a statistical algorithm with data to learn from. This process is known as Machine Learning.
The learning algorithm finds pattern in the data used for training that maps the input features to the target variables; the output is a Machine Learning (ML) model that captures the discovered pattern.
Data Visualization is the process that helps in the communication of the insights and patterns discovered or found in the data. This involves the direct interpretation of the data in a non-technical way, that the business can relate to. It also comes with actionable insights that was discovered through the Data Science process.
This step is where story telling comes in. It is always advisable to let your data tell a story as it is one of the most effective ways of communicating your results.
