C . Works with nominal values
A researcher is interested in how variables, such as GRE (Graduate Record test scores), GPA (grade point average)
and prestige of the undergraduate institution, effect admission into graduate school. The response variable, admit/dont
admit, is a binary variable.
Above is an example of
A . Linear Regression
B . Logistic Regression
C . Recommendation system
D . Maximum likelihood estimation
E . Hierarchical linear models
Pros: Computationally inexpensive, easy to implement, knowledge representation easy to interpret

Which of the following technique can be used to the design of recommender systems?
A . Naive Bayes classifier
B . Power iteration
C . Collaborative filtering
D . 1 and 3
E . 2 and 3
One approach to the design of recommender systems that has seen wide use is collaborative filtering. Collaborative
filtering methods are based on collecting and analyzing a large amount of information on users behaviors, activities or
preferences and predicting what users will like based on their similarity to other users. A key advantage of the
collaborative filtering approach is that it does not rely on machine analyzable content and therefore it is capable of
accurately recommending complex items such as movies without requiring an "understanding" of the item itself. Many
algorithms have been used in measuring user similarity or item similarity in recommender systems. For example the k-
nearest neighbor (k-NN) approach and the Pearson Correlation
Logistic regression is a model used for prediction of the probability of occurrence of an event. It makes use of several
variables that may be
A . Numerical
B . Categorical
C . Both 1 and 2 are correct
D . None of the 1 and 2 are correct
Logistic regression is a model used for prediction of the probability of occurrence of an event. It makes use of several
predictor variables that may be either numerical or categories.
In unsupervised learning which statements correctly applies
A . It does not have a target variable
B . Instead of telling the machine Predict Y for our data X, were asking What can you tell me about X?
C . telling the machine Predict Y for our data X
In unsupervised learning we dont have a target variable as we did in classification and regression.
Instead of telling the machine Predict Y for our data X, were asking What can you tell me about X?
Things we ask the machine to tell us about X may be What are the six best groups we can make out of X? or What
three features occur together most frequently in X?
You are working on a problem where you have to predict whether the claim is done valid or not. And you find that
most of the claims which are having spelling errors as well as corrections in the manually filled claim forms compare
to the honest claims.
Which of the following technique is suitable to find out whether the claim is valid or not?
A . Naive Bayes
B . Logistic Regression
C . Random Decision Forests
D . Any one of the above
In this problem you have been given high-dimensional independent variables like texts, corrections, test results etc.
and you have to predict either valid or not valid (One of two). So all of the below technique can be applied to this
Support vector machines Naive Bayes Logistic regression Random decision forests
If E1 and E2 are two events, how do you represent the conditional probability given that E2 occurs given that E1 has
A . P(E1)/P(E2)
B . P(E1+E2)/P(E1)
C . P(E2)/P(E1)
D . P(E2)/(P(E1+E2)
Which of the following statement true with regards to Linear Regression Model?
A . Ordinary Least Square can be used to estimates the parameters in linear model
B . In Linear model, it tries to find multiple lines which can approximate the relationship between the outcome and
C . Ordinary Least Square is a sum of the individual distance between each point and the fitted line of regression
D . Ordinary Least Square is a sum of the squared individual distance between each point and the fitted line of
Linear regression model are represented using the below equation
Where B(0) is intercept and B(1) is a slope. As B(0) and B(1) changes then fitted line also shifts accordingly on the
plot. The purpose of the Ordinary Least Square method is to estimates these parameters B(0) and B(1). And similarly it
is a sum of squared distance between the observed point and the fitted line. Ordinary least squares (OLS) regression
minimizes the sum of the squared residuals. A model fits the data well if the differences between the observed values
and the models predicted values are small and unbiased.

The role of education as a pathway to opportunity in our country has never been more critical, or more scrutinized. The evidence is clear: Poverty, and the chaos it often brings to a familyâs daily life, severely constricts a childâs ability to engage and succeed in school. How can we make sure our schools are up to the challenge of providing a 21st-century education forÂ allÂ our children â not just some? And what will it take to get there?
Everyone is looking for policy solutions that work.
City Connects works.
In an era of scarce resources and rising need, itâs essential to ensure that existing programs and services are fully utilized and well deployed. City Connects delivers that assurance, creating a systematic approach to addressing the needs of all students.
Even in high-need districts, resources and enrichment opportunities for children are present, both in schools and in the larger community. The challenge is accessing them, amid what can be a cacophonous maze for overtaxed teachers, administrators, or families. At City Connects schools, the City Connects Coordinator is the connecting point, navigating the maze to identify and target the right student to the right service, creating an optimized system of student support.
In 2019-20, City Connects has linked more than 25,000 students to 220,000 services and enrichment opportunities across its sites, ranging from tutoring to athletic programs.
And whatâs more, we have theÂ evidenceÂ to show that these interventions are working â for students, teachers, schools, and families.

Turnover is costly, in terms of both money and culture. Research estimates show that losing an employee costs a company approximately 33% of that employeeâs yearly salary. Additionally, turnover creates gaps in knowledge and rapid change in team and company dynamics. For these reasons, many companies will pull out all the stops to Boost retention, such as delivering complex, expensive initiatives to drive engagement.
Thatâs why Iâm impressed by the simple-in-concept approach taken by Chief Human Resources Officer (CHRO) of SugarCRM Shana Sweeney. By individualizing the companyâs recognition and treatment of employees both at work and in their personal lives, she observed a massive decrease in attrition (from 23% to 9%). This kind of simplification and execution is present in all of Sweeneyâs workâwhether sheâs breaking down leadership development into bite-size chunks to prevent overwhelm, creating project boards that allow people to jump teams and devote 10% of their time to something new, or building out manager panels to bring critical skills to life for her leaders.
With 400 employees, SugarCRM provides a full suite of customer relationship management solutions: marketing automation, salesforce automation, and customer service tools.
SugarCRM Culture Is a âVibrant Tapestry of Empathy, Collaboration, and Passion for Problem-Solvingâ
Highly authentic cultures have a way of pushing through the noise and sounding as unique as they are. âOur culture is a vibrant tapestry of empathy, collaboration, and a shared passion for problem-solving,â Sweeney shared. âWe have core values behind our culture, such as:
Initially, Sweeney shared that she was very skeptical of âYes, ifâ as a human resources (HR) professional. âBut when we analyze problems, we try to push each other to look for the âyes, if.â This frame of thinking leads to a lot of creative problem-solving. It's a very positive, creative way of approaching problems and considering all the possible solutions rather than giving a hard no.â
A Thoughtful Approach to Developing Overwhelmed Leaders
Sweeney noticed that post-pandemic, many leaders at SugarCRM were overwhelmed. With this in mind, she focused on bite-size, highly consumable learning in 2022.
2022: A Weekly Bite-Size NewsletterââIn 2022, we created a weekly newsletter that we named Manager Minute,â Sweeney explained. âThe newsletter provided a short bit of information on a course so that super busy leaders could still take one minute to read it and learn something. Alongside our newsletter, we provided tools, resources, books, and podcast links, where managers could obtain additional information if the course was especially timely or relevant.â
2023: Quarterly Manager PanelsâThis year, Sweeney and her team are taking a more hands-on approach. Each quarter, they train leaders on key development subjects as identified by the executive team. âThe HR team provides a short introduction to the topic. Then, we've selected a panel of managers for each course who are unofficial leaders of that skill. HR facilitates the panel discussion, but all the managers in the room can chime in with questions.â The panel-style approach fosters collaboration and mentorship. Itâs also a nice way to recognize people on the panel for their great work. In addition to the panels, managers have a collaboration channel and access to a portal full of tools, tips, and relevant information. Sweeney and her team use a hands-on approach, providing one-on-one coaching to managers.
The last panel Sweeney and her team conducted focused on managing up. They had received feedback from the executive team that first-line managers could use help managing up for their own benefit as well as their team's benefit. âWe ended up creating profiles of several of the senior leaders in the organization from a style standpoint, and then we gave some recommendations on how to work with those different styles to achieve the desired results,â Sweeney explained.
A Personalized and Humanistic Approach Drives Retention
Since Sweeney became CPO, the company decreased its attrition rate by 14% (from 23% to 9%). She attributes this improvement to her teamâs highly personalized approach. âWe treat people as humans first and employees second. We try to show appreciation and support throughout their employee journey and in their personal life. We do things like send flowers, baby gifts, and handwritten notes to new hires,â Sweeney remarked. âWe take a very personal approach. For example, we've hired a personal chef for an employee whose spouse was frustrated because they were on the road a lot, and for an employee with a serious medical condition, we made sure that their pets were cared for.â
New Undertakings in 2024: Cross-Functional Project Opportunities
Moving into 2024, Sweeney is trying out a project concept where employees can examine projects other teams are working on and potentially devote 10% of their time to that project. âWe're exploring the option of creating a project board and allowing people to apply for projects on which they can allocate 10% of their time to help broaden their skill set outside of their current functional area,â Sweeney said.

In a collaborative, client-centered professional approach, I use biblical principles integrated with cognitive behavioral and solution-focused therapy as interventions for change. This approach is highly effective because the client's emotional, behavioral, contextual, and spiritual needs are addressed. This approach can significantly help all ages across various issues achieve healing, reconciliation, and solutions related to various emotional and psychological problems. Those problems include child behavioral problems, family dysfunction, depression, anxiety, domestic abuse, and relationship problems.
The basis of a Christian worldview, cognitive behavioral, and solution-focused therapy helps clients discover fundamental aspects of socio-emotional psychology, including innate strengths, values, cognition, and identity. I am passionate about the abilities of these tools to assist you in understanding and developing the solutions to manage life's challenges
Contemporary life has various transitions and numerous challenges. My goal over the past three decades of counseling has been to honor and help clients regain their mental and emotional balance as they develop learned behaviors and skills fundamental to the desired outcomes they wish to achieve. I would love the opportunity to be of assistance to you.

A University of Queensland-led research team says the key to a more sustainable food future may be a better understanding of ancient Indigenous food production systems.
Their ARC Discovery project "Testing the Dark Emu hypothesis" combines bioarchaeology, archaeobotany, palynology, ethnobotany and plant genetics in partnership with Indigenous communities to challenge existing perspectives. The research is published in Archaeology of Food and Foodways.
UQ bioarchaeologist Associate Professor Michael Westaway said transdisciplinary research was needed to confirm whether Aboriginal communities were farmers rather than foragers, with evidence of early aquaculture and possibly cultivation.
"We're working closely with Indigenous communities, because Aboriginal people are increasingly hurry to gain insights into how their people cared for Country and developed these types of sustainable food production systems," Dr. Westaway said.
"We've found extensive evidence the largest forager quarries in the world were in western Queensland, where the Mithaka people extracted stone slabs to make grinding stones for processing seeds.
"We've also excavated the fireplaces of gunyahs, traditional Aboriginal huts, and found remnants of burned carbonized seeds, which archaeobotanists are now examining to identify the species."
Dr. Westaway said pollen cores taken from ancient lake beds also allowed the team to reconstruct how the surrounding vegetation had changed over time.
"The ethnohistory shows us that Aboriginal people would prepare for a big flood by burning the surrounding riverine plains, to increase the productivity of the landscape," he said. "By identifying carbon peaks in the cores from the lake beds, we can learn about the timing of the burnings.
"We believe we're seeing records that indicate domestication of landscapes, which is an exciting element."
The research team has also looked at plant genetics, including drought resistance.
UQ Professor of Innovation in Agriculture Robert Henry said a methodical, transdisciplinary approach was necessary to reveal the complete story of ancient Indigenous food production.
"I'm looking at the contemporary flora and how the plants there now might have been changed by humans over time," Professor Henry said. "These can include changes in seed size or whether the plant would have been edible and trying to link that with the archaeological findings.
"This is significant from an agricultural point of view, as there may have been practices in the past that are useful to know about for the future. Climate change means we will have to adapt agriculture to new climates, as they did in the past."
Dr. Westaway said the research had the potential to open new ways of thinking about using native flora in a more sustainable way, that would support new industry.
