Predictive policing computational thinking show and tellArchit Sharma
Predictive policing uses advanced data analysis and technology to predict where and when crimes are likely to occur based on patterns in historical crime data. The predictions are used to more efficiently deploy law enforcement resources to targeted areas in an effort to prevent crimes before they happen. Predictive policing algorithms analyze large datasets on past crimes, including details like type of crime, location, and timing, to identify patterns and assign probabilities of future criminal activity to specific regions.
Predictive policing uses statistical analysis and data to predict criminal activity and identify crime patterns in order to prevent future crimes and solve past cases. It relies on the idea that criminals tend to operate within a "comfort zone" and commit similar crimes in similar locations. Predictive policing involves collecting large data sets, analyzing the data to identify crime hot spots or individuals at risk of offending, intervening through police operations, and assessing the results to continue refining predictions. While predictive policing shows promise, its effectiveness depends on proper implementation and action based on predictions, and it has certain limitations in predicting some types of crimes.

Crime rate analysis using k nn in python
This document summarizes a project aimed at understanding crime patterns in Chandigarh, India. Key factors that could influence crime rates, such as population density, sex ratio, and economic indicators, were identified. Crime data from 1993-2010 was analyzed using regression models. The autoregressive model, which predicts crime based on previous years' crime rates and other factors, achieved the highest accuracy at 90%. Future work will involve applying these models to other Indian cities to improve crime forecasting.
Machine Learning Approaches for Crime Pattern DetectionAPNIC
This document discusses machine learning approaches for predicting crime patterns. It begins by stating the large number of violent crimes in the US and explaining that predicting crimes can help avoid them and ensure better resource allocation. It then discusses existing crime prediction systems like PredPol and the general crime prediction process of data gathering, classification/clustering, and prediction. It provides various methods for data gathering, like crime records, social media, IoT devices, and newspapers. It also discusses clustering algorithms like k-means that can be used. Finally, it notes that PredPol has achieved a 22.7% reduction in crimes in one area, but that combining additional techniques like machine learning, big data analysis, and image processing could further improve crime prediction.

PredPol: How Predictive Policing WorksPredPol, Inc
PredPol’s cloud-based predictive policing software enables law enforcement agencies to better prevent crime in their communities by generating predictions on the places and times that future crimes are most likely to occur.
PredPol’s technology has been helping law enforcement agencies to dramatically reduce crime in jurisdictions of all types and sizes, across the U.S. and overseas. Over the past year, Atlanta and Los Angeles have reduced specific crimes in targeted areas at rates ranging from nearly 20% to over 40%. Smaller jurisdictions, such as Norcross, Georgia, have seen nearly a 30% reduction in burglaries and robberies; in Alhambra, California, car burglaries have dropped 20% since the software technology was deployed.
Using advanced mathematics and computer learning, PredPol’s algorithms predict many types of crime, including property crimes, drug incidents, gang activity, and gun violence as well as traffic accidents.
Only three pieces of data are used to make predictions – type of crime, place of crime, and time of crime. No personal data is utilized in making these predictions.
Crime analysts and command staff using PredPol are 100% more effective than they are with traditional hotspot mapping at predicting where and when crimes are likely to occur. That means police have twice as many opportunities to deter and reduce crime.
Predictive Policing on Gun Violence Using Open DataPredPol, Inc
This presentation is an abstract of a 2013 whitepaper published by PredPol.
PredPol delivers the same predictive accuracy for gun violence using unique mathematical methods. A study of Chicago data shows that PredPol successfully predicts 50% of gun homicides by flagging in real-time only 10.3% of city locations. Knowing where and when gun homicides are most likely to occur empowers law enforcement to use their knowledge, skills and experience to disrupt gun crime before it happens.
The study uses open government data from Chicago and predictive crime analysis.

Crime analysis mapping, intrusion detection using data mining
Data Mining plays a key role in Crime Analysis. There are many different algorithms mentioned in previous research papers, among them are the virtual identifier, pruning strategy, support vector machines, and apriori algorithms. VID is to find relation between record and vid. The apriori algorithm helps the fuzzy association rules algorithm and it takes around six hundred seconds to detect a mail bomb attack. In this research paper, we identified Crime mapping analysis based on KNN (K – Nearest Neighbor) and ANN (Artificial Neural Network) algorithms to simplify this process. Crime Mapping is conducted and Funded by the Office of Community Oriented Policing Services (COPS). Evidence based research helps in analyzing the crimes. We calculate the crime rate based on the previous data using data mining techniques. Crime Analysis uses quantitative and qualitative data in combination with analytic techniques in resolving the cases. For public safety purposes, the crime mapping is an essential research area to concentrate on. We can identity the most frequently crime occurring zones with the help of data mining techniques. In Crime Analysis Mapping, we follow the following steps in order to reduce the crime rate: 1) Collect crime data 2) Group data 3) Clustering 4) Forecasting the data. Crime Analysis with crime mapping helps in understanding the concepts and practice of Crime Analysis in assisting police and helps in reduction and prevention of crimes and crime disorders.

Real time classification of malicious urls.pptx 2Daniyar Mukhanov
This document discusses developing a machine learning system to classify URLs as malicious or benign in real-time. The system was trained on data collected from tweets during two large events - the Super Bowl and Cricket World Cup. A multi-layer perceptron (MLP) model achieved the best performance, correctly classifying 72% of URLs from the unseen Cricket World Cup data within 30 seconds. The Bayesian model performed best in early stages, achieving 66% accuracy within the first 60 seconds. Analysis of the MLP model revealed that bytes received and remote IP address were important indicators of malicious URLs.
This document discusses a project on crime prediction and strategy detection. The objective is to visualize criminal data, detect strategies, analyze criminal datasets, and predict crimes. The methodology involves collecting crime data, preprocessing it, analyzing correlations between crimes, clustering cities, and predicting and visualizing results. Challenges include the increasing size of crime data, identifying accurate analysis techniques, and dealing with inconsistent or incomplete data.
Using Narcotics Arrest Data To Predict Violent Crimechad_e_smith
Dallas has a high crime rate, with over 15,000 gun crimes per year. The Dallas Police Department (DPD) uses basic crime analysis methods to track crime trends over time. DPD targets crime hot spots but needs better tools to predict exact crime locations to lower the overall crime rate. This study will use narcotics arrest data from Dallas PD records to build a Geographically Weighted Regression (GWR) model to predict locations of violent crime. The model will be evaluated by comparing its predictions to actual violent crime data, with the goal of helping DPD deploy resources more efficiently and develop improved crime prevention strategies.
This paper focuses on finding spatial and temporal criminal hotspots. It analyses two different real-world crimes datasets for Denver, CO and Los Angeles, CA and provides a comparison between the two datasets through a statistical analysis supported by several graphs. Then, it clarifies how we conducted Apriori algorithm to produce interesting frequent patterns for criminal hotspots. In addition, the paper shows how we used Decision Tree classifier and Naïve Bayesian classifier in order to predict potential crime types. To further analyse crimes’ datasets, the paper introduces an analysis study by combining our findings of Denver crimes’ dataset with its demographics information in order to capture the factors that might affect the safety of neighborhoods. The results of this solution could be used to raise people’s awareness regarding the dangerous locations and to help agencies to predict future crimes in a specific location within
a particular time.

Propose Data Mining AR-GA Model to Advance Crime analysisIOSR Journals
This document proposes a data mining model to advance crime analysis using association rule (AR) and genetic algorithm (GA). The model has three correlated dimensions: a crime dataset, criminal dataset, and geo-crime dataset. AR will be applied to each dataset separately to extract patterns, then GA will be used to mix the resulting ARs and exploit relationships across the three dimensions. This is intended to help detect universal crime patterns and speed up the crime solving process. The model was applied to real crime data from a sheriff's office and validated. Privacy-preserving techniques are also suggested to hide sensitive rules from appearing in the results.

Supervised and Unsupervised Machine Learning Methodologies for Crime Pattern ...gerogepatton
Crime is a grave problem that affects all countries in the world. The level of crime in a country has a big
impact on its economic growth and quality of life of citizens. In this paper, we provide a survey of trends of
supervised and unsupervised machine learning methods used for crime pattern analysis. We use a spatiotemporal dataset of crimes in San Francisco, CA to demonstrate some of these strategies for crime
analysis. We use classification models, namely, Logistic Regression, Random Forest, Gradient Boosting
and Naive Bayes to predict crime types such as Larceny, Theft, etc. and propose model optimization
strategies. Further, we use a graph based unsupervised machine learning technique called core periphery
structures to analyze how crime behavior evolves over time. These methods can be generalized to use for
different counties and can be greatly helpful in planning police task forces for law enforcement and crime
prevention.

This document discusses using data mining techniques like K-nearest neighbors and artificial neural networks for crime analysis mapping and intrusion detection. It proposes collecting crime data, grouping it, clustering it, and forecasting it to help reduce crime rates. The existing system relies on manual storage and analysis of crime data. The proposed system would use data mining tools like artificial neural networks and knowledge discovery in databases to automatically analyze crime data collected from police to help identify patterns and solve cases. It outlines collecting both supervised and unsupervised crime data, identifying unnecessary data, and using tools like SAM to train on supervised data and solve other cases.

Next, it discusses motivations for using machine learning to predict crimes in advance. The paper then compares different studies that have used techniques like k-means clustering, decision trees, naive bayes, and random forests on crime data. It evaluates these techniques and their limitations in accurately analyzing crime patterns and predicting future crimes. Finally, the document proposes using these machine learning methods and data mining approaches on crime data from Bangalore to help law enforcement agencies
Crime Pattern Detection using K-Means ClusteringReuben George
Crime pattern detection uses data mining techniques like clustering to analyze crime data and identify patterns. This involves plotting past crimes geographically, clustering similar crimes to detect sprees, and analyzing the results to draw conclusions. It helps improve crime solving by learning from history and preempting future crimes. The method augments detectives' work but has limitations like relying on data quality. Overall, crime pattern detection aids operational efficiency and enhancing resolution rates by optimizing resource deployment based on observed crime trends.
Crime analysis involves the systematic study of crime and disorder problems using qualitative and quantitative data. It examines sociodemographic, spatial, and temporal factors to assist police in apprehension, reduction, prevention, and evaluation. Crime analysis developed from early uses of pin maps and began professionalizing in the 1980s. It includes administrative, investigative, tactical, and strategic types. Ratcliffe's Hotspot Matrix examines crime concentrations spatially as dispersed, clustered, or a hotpoint and temporally as diffused, focused, or acute to determine appropriate police tactics. Strategic crime analysis uses tactical analysis to identify long-term community problems and generate innovative solutions in partnership with community policing.
IRJET- Crime Analysis using Data Mining and Data AnalyticsIRJET Journal
This document discusses using data mining and analytics techniques to analyze crime data and predict crime rates. It proposes using linear regression on crime data from the Indian government to predict future crime occurrences and identify high-risk regions. The system would analyze factors like crime type, offender age, month, and year to build a regression model. This model could then predict crime rates and indicate whether a region is high or low risk for criminal activity. Graphs and tables would visualize the predictions to help law enforcement allocate resources. The goal is to help reduce crime and increase public safety by identifying patterns in historical crime data.
An Intelligence Analysis of Crime Data for Law Enforcement Using Data MiningWaqas Tariq
The concern about national security has increased significantly since the 26/11 attacks at Mumbai, India. However, information and technology overload hinders the effective analysis of criminal and terrorist activities. Data mining applied in the context of law enforcement and intelligence analysis holds the promise of alleviating such problem. In this paper we use a clustering/classify based model to anticipate crime trends. The data mining techniques are used to analyze the city crime data from Tamil Nadu Police Department. The results of this data mining could potentially be used to lessen and even prevent crime for the forth coming years

Predictive Policing: Using Technology to Reduce Crime
By Zach Friend, M.P.P.
4/9/2013
Nationwide law enforcement agencies face the problem
of doing more with less. Departments slash budgets
and implement furloughs, while management struggles
to meet the public safety needs of the community. The
Santa Cruz, California, Police Department handles the
same issues with increasing property crimes and
service calls and diminishing staff. Unable to hire more
officers, the department searched for a nontraditional
solution.
In late 2010 researchers published a paper that the
department believed might hold the answer. They
proposed that it was possible to predict certain crimes,
much like scientists forecast earthquake aftershocks.
An “aftercrime” often follows an initial crime. The time and location of previous criminal activity helps to
determine future offenses. These researchers developed an algorithm (mathematical procedure) that
calculates future crime locations.1
Equalizing Resources
The Santa Cruz Police Department has 94 sworn officers and serves a population of 60,000. A
university, amusement park, and beach push the seasonal population to 150,000. Department personnel
contacted a Santa Clara University professor to apply the algorithm, hoping that leveraging technology
would improve their efforts. The police chief indicated that the department could not hire more officers.
He felt that the program could allocate dwindling resources more efficiently.
Santa Cruz police envisioned deploying officers by shift to the most targeted locations in the city. The
predictive policing model helped to alert officers to targeted locations in real time, a significant
improvement over traditional tactics.
Making it Work
The algorithm is a culmination of anthropological and criminological behavior research. It uses complex
mathematics to estimate crime and predict future hot spots. Researchers based these studies on

Predictive analysis of crime forecastingFrank Smilda
This document discusses various methods for predictive crime mapping, beginning with simply using past crime "hot spots" as a predictor of future hot spots. While this approach has limited accuracy over short periods, past hot spots can predict up to 90% of future crime over longer periods like a year. The document then reviews more sophisticated predictive modeling methods and the role of geographic information systems in developing spatial models to predict crime.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.
1. Crime Analysis of Different
Situations and Prediction of
Similarities Between Crimes
Project Guide: By:
Mrs.S.Usha Manjari P.Pawan(17311A12D2)
Asst.Professor K.Akhil((17311A12E1)

2. Abstract
Abstract:
There has been enormous increase in the crime rate last few
years, especially in urban places of India . It is estimated that
about 80.7% of population in USA lives in cities and by the
year 2030 about 60% of world population might reach the cities
of their respective nations . So it will be a major task for Police
departments and Government to keep a check on crimes
happening in the state/country.
3. One effective way of reducing the crime rate is “Analysing the
Crimes by studying Previous Crimes” and “Predicting the crimes” by
studying the link and similarities between them. As once said “Prevention is
better than Cure”, predicting the crimes efficiently before happening will ensure
maximum safety and security of citizens. It also makes E-Governance easy.
So here we use statistical prediction methods which identify the
likely targets to prevent crime events. The techniques which we are going to use
are done with the help of historic information,social media etc.
Broken Window Theory was the base for this Crime Prediction.
4. Previous Works:
LAPD has been implementing “Predictive Policing” past few years and has
been successful in decreasing the crime rate in few situations.
States like Chicago , New York , Brisbane , LA etc. are using
“Operation Laser” in their respective states and predicted few major crimes
before happening and stopped them.
“Chronic Offender Points System” which is playing an important
role in Criminal catching has its advantages and Disadvantages.It uses
“Point System” which sometimes fail in catching the right person which is a
big problem.
5. Our Approach
We want to offer few amendents for “Chronic Offender
System” with the help of proper analysis and algorithms.
Our major task is “Analysing the crimes based on
interesting Patterns obtained from Previous crimes”
Our work involves Visualization techniques.
We want to visualize what kind of crimes and time of
occurences of most crimes so that we could make
preventive measures.
18. Chronic Offender Point System
Our take on “Chronic Offender Point System”
What is this “Chronic Offender Point System”:
One effort, known as Operation LASER, which began in 2011,
crunches information about past offenders over a two-year
period, using technology developed by the shadowy data
analysis firm Palantir, and scores individuals based on their rap
sheets.
19. Alternatives For COPS:
1)Location based Predictive Policing may help to find crime
hotspots but implementing Pattern based Predictive
Policing may find real culprit.
2)We,the group inspired from daily life examples and
investigative documentaries would like to share this idea.
According to us Patterns are most important in crime
investigation. The steps involved are:
1)Record the crime and also the pattern of its occurrences.
2)Save each crime pattern differing into different files
3)Try to match and classify each crime accordingly
4)As and when a culprit is caught assign him with the crime
