Posted on by faz_business


Estimated reading time: 2 minutes

In our last video on how to delete a key from a python dictionary, we illustrated where one key could be removed easily.

But what if you wanted to remove one or more keys?

How to delete more than one key from a Python dictionary

In the below code, we have created an empty dictionary. This will be populated by values in “dictionary_remove”.

Option1 uses the pop method :

  1. It creates an empty dictionary and then populates it with keys and values.
  2. Then it uses a loop to iterate over the list dictionary_remove.
  3. Then it looks at those and uses the pop method to find those values in the empty_dict1, and removes them

As a result, the following is what is returned:

Before:

{‘Key2’: ‘2’, ‘Key1’: ‘1’, ‘Key3’: ‘3’, ‘Key4’: ‘4’, ‘Key5’: ‘5’, ‘Key6’: ‘6’}

After:

{‘Key2’: ‘2’, ‘Key1’: ‘1’, ‘Key3’: ‘3’, ‘Key4’: ‘4’}

Option 2 uses the Del method :

In this second scenario, we do the following steps:

  1. We populate the dictionary_remove with two values, that are from the result of scenario 1 above.
  2. Then it uses a loop to iterate over the list dictionary_remove.
  3. Then it looks at those and uses the del method to find those values in the empty_dict1, and removes them

As a result, the following is what is returned:

Before:

{‘Key2’: ‘2’, ‘Key1’: ‘1’, ‘Key3’: ‘3’, ‘Key4’: ‘4’}

After:

{‘Key2’: ‘2’, ‘Key1’: ‘1’}

Slide 8
#How to delete more than one key from a dictionary
#1. Create a list to lookup against
empty_dict1 = {}

empty_dict1['Key2'] = '2'
empty_dict1['Key1'] = '1'
empty_dict1['Key3'] = '3'
empty_dict1['Key4'] = '4'
empty_dict1['Key5'] = '5'
empty_dict1['Key6'] = '6'

print(empty_dict1)

dictionary_remove = ["Key5","Key6"] # Lookup list

#1. Use the pop method

for key in dictionary_remove:
  empty_dict1.pop(key)
print(empty_dict1)

#2 Use the del method
dictionary_remove = ["Key3","Key4"]
for key in dictionary_remove:
  del empty_dict1[key]
print(empty_dict1)

Banks need emotion recognition software to increase customer loyalty

Posted on by faz_business


As the U.S. retail banking market demonstrates a heating competition for the biggest share of wallet, most banks see customer experience (CX) as their competitive advantage helping to grow the number of loyal customers. Though CX professionals have long been using numerous measurement systems and banking software solutions to increase customer loyalty, they seem to overlook one vital component: emotion-based market research.

Let’s see why analyzing customers’ emotions is a must for banks striving to provide excellent customer experience.

Customer loyalty emotion recognition software

What customers say is NOT what they mean

As stated by Gerald Zaltman, a professor from Harvard Business School, 95% of purchasing decisions take place in the subconscious. However, later customers begin to rationalize these so-called gut-level reactions. That is why, when consumers try to explain what they need from a bank, their rational thoughts influence responses. As a result, the majority of customers typically mention only reasonable needs, such as convenience of branches, interest rates, partner programs, etc. thereby omitting real desires led by emotions.

Deep emotions increase customer loyalty

However, the most successful world’s brands across various industries swiftly realized the power of emotions and brought to perfection the art of connecting with customers at the emotional level. These brands captured customers’ hearts and minds by revealing their fundamental and thereby often unspoken emotional motives, such as the need to stand out from the crowd or to feel a sense of belonging, freedom, etc.

For example, Cottonelle Kleenex brand became internationally famous and gained millions of loyal customers thanks to a clever promotion featuring cute Labrador puppies. Aimed to evoke a sense of happiness, this marketing trick deeply resonated with customers making them loyal to such an unpretentious product as toilet paper. The launch of the Nike+ online community has deeply resonated with customers’ desire to belong to a large group increasing their loyalty and the brand’s revenue.

Customer loyalty emotion recognition software

Why studying emotions is essential for banks

While the world known brands put much effort into exploring the inner motives and emotions that define customer behavior, most bank still hope to increase customer loyalty with barely perceptible means, such as offering slightly higher savings rates. This approach is doomed to failure from the beginning, as Millennials, the largest generation in American history, express no feelings of customer loyalty and think their banks cannot offer anything different from other banks. Thus, instead of focusing on short-term goals to increase the amount of deposits, banks should go for establishing long-lasting relationships with customers. As competently noted by Duena Blowstrom, feelings can pay off far better than numbers.

Establishing an emotional connection with customers, a bank can become a partner for customers rather than merely stay a place to keep their money. Though a checking account, CD or credit card themselves may not evoke the same emotional effect as, say, a pair of sneakers, it doesn’t mean banks should neglect customers’ emotions at all. To create deeper connections with customers, banks should not just offer a variety of loyalty programs. Rather, they should strive to become loyalty brands themselves like Apple or Nike do.  

If banks underestimate the value of emotions, they risk getting distorted insights about customers’ wants and needs and consequently may choose a wrong marketing and sales strategy. The consequences of such imprudence are numerous: from low return on marketing and sales investments to poor customer experience and customers’ churn to another bank. Still, there’s a chance to avoid these outcomes with the help of technology. 

How to recognize and analyze customers’ emotions

With our rich experience in banking software consulting, we’ve worked out a number of tips to carry out an in-depth analysis of customers’ emotions.

To define which emotions trigger purchase behavior, the first step is gathering data about a particular customer segment (e.g., the Millennial generation, the most profitable group of customers). Depending on budget, a bank can focus on conducting retrospective CX surveys (e.g., NPS, CSAT or CES) or measure emotions in real-time. In the latter case, banks can choose among a wide variety of emotion recognition technologies, such as text, voice or image analysis software.

Text analysis software uses natural language processing to identify whether a statement is generally positive or negative according to the language style as well as keywords and their valence index. Banks can use this software to analyze customers’ sentiments in their text reviews about products and the quality of their services. Voice analysis software uses recorded or live customers’ speech to uncover tone and word content. Image analysis software detects facial emotions within a photo or video. To identify customers’ expressions, image analysis software establishes relationships between points on the face and compares them with database files. Voice and image analysis software can be of great help in a branch providing real-time ’emotion data’ for customer service representatives.

Once a bank finished with the first step, it’s time to systematize and analyze ’emotion data’. Using data analysis software, based on statistical analysis techniques, such as multivariate regression and structural equation modeling, a bank can determine which emotional motivators correspond to a chosen focus group and which of these emotions create the most value for the bank.

After choosing ‘the most valuable emotions’, a bank should then anchor on it by creating consistent customer communications focused on this particular emotional need. At this final stage, every point of contact from content to customer service should reinforce customers’ emotional perception of the bank. A bank that manages to link itself with customers’ emotional motivators will communicate with customers more effectively thereby increasing their experience and loyalty.  

Emotions are a universal language to connect with your customers

To achieve meaningful CX results, banks should use solutions for big data analytics and image recognition software to carry out an in-depth analysis of customers’ emotions and adopt the results in their CX strategy. Taking into account customers’ emotional needs will help banks to better engage with their customers, create deeper communications and build brand loyalty.

AML solution for Gaming Industry

Posted on by faz_business


Back in November 2022, the European Comission (EC) published a report on the prevalence of money laundering in the iGaming industry, flagging it at the highest level of threat. They observed that the online gaming industry had several weaknesses regarding AML regulations and hinted at stricter regulations to come.

Coincidentally, it was around the same time when Rishi Sunak was forming the government. This amplified the rumors of looming bottle-neck regulations for the gaming industry. There was also the speculation of the UK Gambling Commission trying to implement a “single customer view” across all operators’ platforms in the country. [1]

3 weeks ago, every prominent igaming news site was covering the new AML guidelines published by the EGBA. The main aim of the report was to provide a more specific and standarized approach for AML regulations, an issue that was pointed out way earlier. Quoting news sources, the EC recommended improvements to its members. “It stated that they should lower the winnings threshold, subject to proper customer due diligence policies, to below the current level of €2,000. In addition, with the assistance of their respective jurisdictional regulators, it wants operators to ensure users can’t create multiple accounts” [2]

For online casinos and sportsbooks, it is quite a challenge to identify and flag suspicious activity or multi-accounting with such massive influx of data flowing by the hour. Operators can however, rely on AI/ML algorithms to stay compliant and ensure they effectively curb money laundering at their casino.

One model that is used across industries to ensure that users do not create multiple accounts is player deduplication’.

Deduplication is a process of removing duplicated data or records from a database or data set. This process helps to identify cases where a single player might be using multiple accounts. Fuzzy matching is the algorithm used for deduplication that compares records on the similarity of users. It makes a decision on whether they might be the same person under different aliases by using a set of rules to calculate the similarity level between records based on specific criteria. The similarity score is then used to determine if two records represent the same entity.

Similarly, an AML model can identify patterns and anomalies based on known patterns of suspicious behavior from historical data (such as money dumping) to detect potential money laundering in real-time.

Money dumping refers to a tactic where a player intentionally loses a large sum of money in a game to transfer the funds to another player in order to evade taxes or to launder money, as the transferred funds appear as winnings rather than a direct transfer. A player may launder a large sum of money by opening multiple accounts under different aliases (called ‘mule accounts’) and distribute this cash across accounts to avoid suspicion. Machine Learning becomes a casino’s best friend when it comes to monitoring and flagging such transactions that are otherwise hard to detect.

Why GAMWIT’s AML model stands out

Exclusively built for the gaming and sports-betting industry

Strong research and development backed by a leadership team with 100+ years of collective experience in gaming analytics. GAMWIT’s AML model flags risky players and segments them into high risk, medium risk, low risk or no risk buckets based on suspicious laundering activity. The model output contains relevant information such as the relationship between each predictor variable with the target variable. It also provides a Predicted vs Actual Analysis of the model outcome for maximum transparency.

Analyzes the journey of money

The model analyzes the journey of money from deposit to encashment while also taking individual player behavior into account in order to predict suspicious behavior early in the business cycle. It is often difficult to track both player behavior and the complete journey of money individually. A combined analysis of the same ensures a full picture is provided to the operator to follow the highest standards of safety and compliance.

For example, the model detects

  • Sudden unusual spikes in deposit amount in a player’s account
  • When a player deposits large amount of money and withdraws after minimum threshold spend or wagering
  • When a player’s visit frequency is inconsistent and involves large sum deposit and withdrawals
  • When a player intentionally loses large amounts of money in a game to transfer the funds to another player in a series of different games
  • These are few ways the AML model flags suspicious activity and informs the operator along with relevant insights on their individual behavior.

Country-specific regulations tracking

The model also takes into account the country-specific regulations of each player to segment the level of risk involved according to the country-specific jurisdiction. Any change in jurisdictions will be updated on the model promptly without any additional cost or complication to the operator.

How Would You Change The Name Of a Key in a Python Dictionary

Posted on by faz_business


In our last example of working with dictionaries, we showed you How To Delete a Set of Keys From a Python Dictionary. This is a very useful scenario if you want to tidy up the dictionary and remove data not required.

Following on from that, in this post, we are going to look at changing key names. You may find that you have the dictionary you want but you need to change some of the key names to ensure the proper names are consistent with other parts of your program.

How would you change the name of a key in a Python dictionary

Option1 uses the pop method :

  1. Create a dictionary with the key-value pairs in it. Note that this will also be used for the second option.
  2. Then this line European_countries[“United Kingdom”] = European_countries.pop(“UK”) basically says to find “UK” in the values, drop it and replace it with the value “United Kingdom”

Before the values using the pop method where:

{‘Ireland’: ‘Dublin’, ‘France’: ‘Paris’, ‘UK’: ‘London’}

After the values using the pop method are:
{‘Ireland’: ‘Dublin’, ‘France’: ‘Paris’, ‘United Kingdom’: ‘London’}

Option 2 uses the zip method :

  1. In this scenario, we have created a dictionary called European countries.
  2. the objective here is to replace the names with the three-letter country code.
  3. Note it updates the values into new_dict using zip, and using the update_elements list, based on the order they are in, in both.

Before the values using the zip method where:

{‘Ireland’: ‘Dublin’, ‘France’: ‘Paris’, ‘United Kingdom’: ‘London’}

After the values using the zip method are:
{‘IRE’: ‘Dublin’, ‘FR’: ‘Paris’, ‘UK’: ‘London’}

#Slide 9
# How do you change the name of a key in a dictionary
#1. Create a new key , remove the old key, but keep the old key value

# create a dictionary
European_countries = {
    "Ireland": "Dublin",
    "France": "Paris",
    "UK": "London"
}
print(European_countries)
#1. rename key in dictionary
European_countries["United Kingdom"] = European_countries.pop("UK")
# display the dictionary
print(European_countries)

#2. Use zip to change the values

European_countries = {
    "Ireland": "Dublin",
    "France": "Paris",
    "United Kingdom": "London"
}

update_elements=['IRE','FR','UK']

new_dict=dict(zip(update_elements,list(European_countries.values())))

print(new_dict)

NoSQL Databases: Defined and Explained

Posted on by faz_business


Editor’s note: Alex overviews NoSQL databases, their major benefits and limitations, and outlines the most popular NoSQL database typology. In case you need expert help with developing a high-performing NoSQL database, check ScienceSoft’s offering in database development services.

If you’ve been around databases for a considerable amount of time, you’re familiar with SQL databases. They generally have a rigid structure due to their schemas and are only vertically scalable, meaning you can only increase performance by buying expensive hardware.

SQL excels at reducing duplicate content, which helps keep the cost of storage down. It was great during the 1970s, 1980s, and 1990s, when storage came at an expensive premium, but not so much in the 2000s, 2010s, and beyond, when storage is ridiculously cheap.

As such, there was no real reason to stick to the constraints of SQL, and that’s how NoSQL was born.

NoSQL (aka ‘not only SQL’) databases can store and retrieve data that is modeled other than the tabular relations in SQL databases, which makes them particularly useful for managing big data.

nosql databases

Advantages of NoSQL

Flexibility

NoSQL databases are essentially freeform as they don’t use a schema, and they aren’t relational. This NoSQL characteristic is due to design rather than a specific language created to deal with database management, so you can use several different data models with NoSQL, depending on your needs.

Scale-out architecture

NoSQL is horizontally scalable, which means you don’t need to buy expensive hardware but can simply throw another shard in, and you’re good to go. As a result, NoSQL is essentially infinitely scalable depending on how far you need to take it, with the expansion itself being relatively easy.

Reduced development costs

Since NoSQL doesn’t generally use a schema, there’s no need to hire a schema designer. You also don’t have to worry about adding new fields or data types since you can pretty much mix and match things to your heart’s desire making the database design process less tedious. Thus, you’ll have easier database setup, rollout, and day-to-day maintenance and use.

Challenges of NoSQL

Data consistency

The primary drawback is that many NoSQL databases compromise consistency. While most relational databases abide by ACID principles (Atomicity, Consistency, Isolation, Durability), the same can be said only about a small percentage of popular NoSQL databases (e.g., Azure Cosmos DB, Amazon DynamoDB). In layman’s terms, an ACID guarantee means that the database you’re using won’t lose any data unless intended.

Lack of development talents

NoSQL is not as widely used as SQL, so there aren’t many NoSQL experts lying around idly. Combine that with the fact that there is a considerable number of different NoSQL data models to be knowledgeable about, and you’re looking at an uphill climb finding experts.

For the most part, you’ll have to rely on smaller expert communities and the database’s own documentation to get answers to any arising questions.

Scalability

Another issue is that NoSQL takes up a ton of storage since it ignores data duplication (and sometimes requires it by definition). Likely you’ll end up needing an order of magnitude of storage higher than an SQL database. However, as data storage is relatively cheap nowadays, this need won’t impact you too much in the long run.

Consider Developing a Solid NoSQL Database Solution?

ScienceSoft will help you design, develop and deploy a fitting NoSQL database solution to get your data organized and easy-to-manage.

Types of NoSQL Databases

While there are several dozen NoSQL databases, they essentially rely on only a few data models.

Key-Value Store

Key-value stores use a hash table that stores a pointer, which is the key, which then points to a value that stores some form of information or data. Ergo the name, key-value!

This type of data model is really versatile due to the fact that data can be a mix and match of pretty much anything, so you can find a database to fit any specialized needs. No wonder key-value stores are considered one of the most popular data models for NoSQL databases.

Moreover, key-value stores are excellent for high-performance and/or high-volume use cases. For example, the key-value database DynamoDB manages to serve millions of people across the globe nearly every second.

Column-oriented

Rather than storing the data in a row, this type of data model stores information in columns nestled inside other families of columns. Imagine columns, inside groups, inside columns.

Since data is contained in such an efficient manner, column-oriented databases have great data aggregation capabilities and data access performance. On the flip side, complex querying certainly becomes a letdown.

Document Stores

Document stores don’t tie XML and JSON together in the traditional way SQL would. And when these two are uncoupled from each other, they can perform at peak efficiency not forced to go as fast as the slowest denominator. There are even some NoSQL databases specifically made for XML, which is neat.

Interestingly enough, document stores are sometimes considered a sub-type of key-value stores, but this data model subtype is big enough to get its own section. Part of its popularity is its flexibility since you can throw in any data type you want.

Graph

As you might have guessed by the name of this data model, it is perfect for a database that represents information in graph form.

With this data model type, information is stored as both nodes and edges. More specifically, the nodes store such information as addresses, names, dates, and so forth, whereas the edges describe the relationships between the different nodes. It allows graph data models to show the relationships between often disparate sets of data, helping you tease out relevant and useful information.

Time to let your business grow with NoSQL

NoSQL databases can be incredibly powerful, though they aren’t cut out for replacing SQL. In fact, they’re meant to work with and complement SQL databases. If you need any assistance with designing, developing, and integrating a NoSQL database into your analytics or development environment, reach out to ScienceSoft’s team.

Reflecting on our social actions at BizAcuity, like the Goonj Donation Drive for the annual floods in Assam, was a compassionate step toward humanity. The impact of our efforts in a city 2,500 miles away brought a heartwarming sense of fulfillment amid the devastating floods in Assam.

Our association with the Goonj Foundation exemplified the importance of collaboration and portrayed cross-sectoral cooperation in driving meaningful change. By joining forces with a well-established NGO like Goonj, we were able to combine our respective strengths and resources to amplify the impact of our collective efforts.

For me, being a part of this donation drive was more than just a week-long project. It was an opportunity to contribute to something bigger than myself, to be a part of a movement that transcends age and background. The journey held more value, from planning, scheduling, and requesting to thanking the employees- these steps played an integral part in developing my empathetic self as a learning individual.

Through initiatives like these, young people like us gain the opportunity to amplify our voices and take meaningful action. It is a reminder that no matter how young we are, we foster the power to create positive change and leave a lasting impact on the world, connecting different communities and building an inclusive society.

Ultimately, this experience displayed how no matter where we come from or what industry we work in, we all have a role to play in creating a better world.

In our latest post, we are going to discuss formatting issues that you may come across. It relates to how you format the data when passing it from the input of a user.

This scenario can happen as a result of user input, which then has some comparisons completed on it.

How does the problem occur?

The problem occurs when you pass the data, but do not format it correctly before you present it in the output.

In the below code you will see these lines:

print ("'{0}' is older than '{1}'"% age1, age2)
print("'{0}'is younger than '{1}', that looks correct!" % age1, age2)

The specific problem is that when you put the % before age1, and age 2 you will get this TypeError.

Why does the problem occur?

This problem occurs as the way you are referencing age1 and age2 has been deprecated.

For reference please look at PEP 3101 – Advanced String Formatting, but essentially if you are using % it is the old way of achieving this!

How can the problem be fixed?

So to fix this please look at the below code:

age1 = input("Please enter your age: ")
age2 = input("Please enter your father's age: ")

if age1 == age2:
    print("The ages are the same, are you sure?!")
if age1 > age2:
    #print ("'{0}' is older than '{1}'"% age1, age2)
    print("'{0}' is older than '{1}', you better check!" .format(age1, age2))
if age1 < age2:
    print("'{0}'is younger than '{1}', that looks correct!" % age1, age2)
    #print("'{0}'is younger than '{1}', that looks correct!".format(age1, age2))

As you can see, I have included the old incorrect code and the new correct code, and when I use the proper Python logic, it gives me the correct output as follows:

Please enter your age: 25
Please enter your father's age: 28
'25'is younger than '28', that looks correct!
