Detection of anomalous trajectories is an important problem for which many algorithms based on learning of normal trajectory patterns have been proposed. Yet, these algorithms are typically designed for offline anomaly detection in databases and are insensitive to local sub-trajectory anomalies. Generally, previous anomaly detection algorithms often require tuning of many parameters, including ad-hoc anomaly thresholds, which may result in overfitting and high alarm rates. The main contributions of this paper are two-fold: The first is the proposal and analysis of the Inductive Conformal Anomaly Detector (ICAD), which is a general and parameter-light anomaly detection algorithm that has well-calibrated alarm rate. ICAD is a generalisation of the previously proposed Conformal Anomaly Detector (CAD) based on the concept of Inductive Conformal Predictors. The main advantage of ICAD compared to CAD is the improved computational efficiency. The only design parameter of ICAD is the Non-Conformity Measure (NCM). The second contribution of this paper concerns the proposal and investigation of the Sub-Sequence Local Outlier (SSLO) NCM, which is designed for sequential detection of anomalous sub-trajectories in the framework of ICAD. SSLO-NCM is based on Local Outlier Factor (LOF) and is therefore sensitive to local sub-trajectory anomalies. The results from the empirical investigations on an unlabelled set of vessel trajectories illustrate the most anomalous trajectories detected for different parameter values of SSLO-NCM, and confirm that the empirical alarm rate is indeed well-calibrated.
A well-known feature of the IOD is its skewness, whereby positive IOD events tend to grow much larger than negative IOD events (so that the IOD is positively skewed). Observations suggest that the positive IOD skewness primarily reflects the negative SST skewness in IODE SST, as the western pole of the IOD exhibits only a weak positive SST skewness40,41. The negative skewness of IODE is caused by a positive Bjerkness feedback involving the SST response to the depth of the thermocline in the eastern Indian Ocean: cold IODE SST anomalies lead to a zonal SST gradient that drives an easterly wind anomaly in the equatorial Indian Ocean, which further shoals the thermocline in the eastern Indian Ocean, reinforcing the cold SST anomalies there5,14,40.
The Anomaly sub download
it's only hardware hungry if you download a modpack full of graphical mods, even then your pc could probably handle it, i have a way worse one and can play just fine at 50 fps, plus you could always change a lot of settings to make the game look like a potato but run like butter
i'd just like to thank you for the abundance of various items in this mod. my entire life i mostly just played the vanilla versions of stalker and only tried out around 5-10 mods briefly. most of them were mediocre and poorly-built. but anomaly is obviously high-quality. since everyone already knows how good anomaly generally is, in my comment i'd like to thank you for something else which i don't think most people mention.for instance when playing the vanilla version of shadow of chernobyl, it was so nice to have two versions of the ecologist suit - a regular one and an improved one. and i kept thinking to myself: WHY NOT ADD MORE VARIATIONS? and this mod is so awesome - there are like 8 different versions of the ecologist suit! each with its own unique properties! this makes me so happy. oh and also the abundance of armor types and weapons in general is so cool. and it's awesome to have ecologists also wear actual body armor protecting from bullets. there's so much variety in this game, factions are so different, character models vary greatly and npcs utilize tons and tons of armor and weapon types, this is amazingly refreshing and im so happy to see variety and versatility in this game. thank you for adding dozens of new armor suits, thank you for adding dozens of new guns and thank you for making npcs actually have different models and utilize those items! this is just awesome, i love the huge amount of various items you have in this mod, this is exactly what vanilla stalker lacks and it's like somebody heard my thoughts and implemented this. thank you! have a good day
The Microsoft Defender for Cloud Apps anomaly detection policies provide out-of-the-box user and entity behavioral analytics (UEBA) and machine learning (ML) so that you're ready from the outset to run advanced threat detection across your cloud environment. Because they're automatically enabled, the new anomaly detection policies immediately start the process of detecting and collating results, targeting numerous behavioral anomalies across your users and the machines and devices connected to your network. In addition, the policies expose more data from the Defender for Cloud Apps detection engine, to help you speed up the investigation process and contain ongoing threats.
The anomaly detection policies are automatically enabled, but Defender for Cloud Apps has an initial learning period of seven days during which not all anomaly detection alerts are raised. After that, as data is collected from your configured API connectors, each session is compared to the activity, when users were active, IP addresses, devices, and so on, detected over the past month and the risk score of these activities. Be aware that it may take several hours for data to be available from API connectors. These detections are part of the heuristic anomaly detection engine that profiles your environment and triggers alerts with respect to a baseline that was learned on your organization's activity. These detections also use machine-learning algorithms designed to profile the users and sign in pattern to reduce false positives.
You can see the anomaly detection policies in the portal by selecting Control then Policies. Then choose Anomaly detection policy for the policy type.
These policies look for activities within a single session with respect to the baseline learned, which could indicate on a breach attempt. These detections leverage a machine-learning algorithm that profiles the users log on pattern and reduces false positives. These detections are part of the heuristic anomaly detection engine that profiles your environment and triggers alerts with respect to a baseline that was learned on your organization's activity.
Each anomaly detection policy can be independently scoped so that it applies only to the users and groups you want to include and exclude in the policy.For example, you can set the Activity from infrequent county detection to ignore a specific user who travels frequently.
You can triage the various alerts triggered by the new anomaly detection policies quickly and decide which ones need to be taken care of first. To do this, you need the context for the alert, so you can see the bigger picture and understand whether something malicious is indeed happening.
This enables you to understand what the suspicious activities are that the user performed and gain deeper confidence as to whether the account was compromised. For example, an alert on multiple failed logins may indeed be suspicious and can indicate potential brute force attack, but it can also be an application misconfiguration, causing the alert to be a benign true positive. However, if you see a multiple failed logins alert with additional suspicious activities, then there's a higher probability that the account is compromised. In the example below, you can see that the Multiple failed login attempts alert was followed by Activity from a TOR IP address and Impossible travel activity, both strong indicators of compromise (IOCs) by themselves. If this wasn't suspicious enough, then you can see that the same user performed a Mass download activity, which is often an indicator of the attacker performing exfiltration of data.
The International Research Institute for Climate and Society Data Library (IRIDL) is a powerful and freely accessible online data repository and analysis web-service that allows a user to view, analyze, and download hundreds of terabytes of climate-related data through a standard web browser in a computer or a smartphone. A wide variety of operations, from simple anomaly calculations to more complex EOF or cluster analyses can be performed with just a few clicks.
Downloading S2S Data has never been easier: data can be subsetted and post-processed (such as ensemble or weekly averaging) prior to download, potentially reducing the required bandwidth. A GUI interface provides interactive data selection, filters (e.g. averaging), views and download, while the Ingrid scripting language provides full control. Several examples are shown below. Individual post-processed data can be downloaded interactively through log in to the IRIDL authorization service (and one-time sign-off on the S2S data Terms & Conditions from ECMWF), or from the unix command line via curl (and similar programs) and a security access key. Details on how to use curl directly in the command line, or how to have it working in different coding languages can be found in the IRI Wiki site.
Figure 1a shows the weekly rainfall anomaly July 6-12, 2015, constructed from CHIRPS daily 0.25-deg rainfall data. Anomalously dry conditions were present over peninsular India, with anomalously heavy rainfall to the northeast over the Indogangetic plain and Himalayan foothills, forming a dipolar pattern characteristic of the Boreal summer intraseasonal oscillation (BSISO), aka the summertime MJO. The Ingrid script used to make this map is shown in Fig. 2a. The GRID function regrids the 0.25-deg data to 1.5-deg for comparison with S2S data. Apentad climatology is then loaded, regridded linearly in time to daily and then subtracted from the CHIRPS, before summing over the July 6-12 range; units are converted to mm/week. 2ff7e9595c
