You should look at it from an engineering perspective. When you accept other types as vectors, you have to write some code to handle that types and cast it in certain scenarios. Especially the performance optimizations parts of spark have to cover such scenarios (check this answer why vectors are beneficial in general).

That would force every developer of a machine learning algorithm for spark to implement a lot of code to cover plenty of different scenarios. When you combine all that code (and keep it out of the machine learning algorithms like standard scaler), you get something like the current vectorassembler. This keeps the code of standard scaler and other algorithms cleaner, as he only has to handle vectors.

vector is not actually built into C++, it is only part of its standard library which is guaranteed to be available to you if you use C++. vector (or, by its full name, std::vector) is itself implemented in C++.

By writing #include , you are telling the compiler to not only use your own code, but to also compile a file called vector. This file is actually somewhere on your harddrive (if you use GNU/Linux, it's probably located at /usr/include/c++/[GCC_VERSION]/vector).

If some programs use std::vector without including its header file, it's because some header file that they have already included, has an #include somewhere. There may be good reasons for that (e.g. some C++ courses ship with a file that includes all necessary headers and that is used in the first few lessons). However there may also be standard library headers that include vector (some implementations of iostream do that). Relying upon that is not a good idea because it differs from implementation to implementation, so your program might work in Visual C++ 2010, but it doesn't compile on GNU or in a newer version of Visual C++.

You need to include the header file, to use any type of data/function. All the data types and functions in c++ are included in their own libraries.If you dont include the library, the c++ program won't know what you used, because it doesnt know they even excist.Its like :

Since the implementation of Roll Back Malaria, the widespread use of insecticide-treated nets (ITNs) and indoor residual spraying (IRS) is thought to have played a major part in the decrease in mortality and morbidity achieved in malaria-endemic regions. In the past decade, resistance to major classes of insecticides recommended for public health has spread across many malaria vector populations. Increasingly, malaria vectors are also showing changes in vector behaviour in response to current indoor chemical vector control interventions. Changes in the time of biting and proportion of indoor biting of major vectors, as well as changes in the species composition of mosquito communities threaten the progress made to control malaria transmission. Outdoor biting mosquito populations contribute to malaria transmission in many parts of sub-Saharan Africa and pose new challenges as they cannot be reliably monitored or controlled using conventional tools. Here, we review existing and novel approaches that may be used to target outdoor communities of malaria vectors. We conclude that scalable tools designed specifically for the control and monitoring of outdoor biting and resting malaria vectors with increasingly complex and dynamic responses to intensifying malaria control interventions are urgently needed. These are crucial for integrated vector management programmes designed to challenge current and future vector populations.

Despite the substantial gains achieved by the Roll-back Malaria initiative (RBM) since the late 1990s, much of the African continent remains highly endemic for the disease and 93% of malaria deaths occur in this region [1]. Malaria control strategies in sub-Saharan Africa (SSA) rely heavily on programmes targeting vector populations through chemical interventions such as insecticide-treated bednets (ITNs) and indoor residual spraying (IRS). These tools are estimated to have contributed to a 68% and 10% decrease, respectively, of malaria cases since the beginning of their broad-scale implementations in the early 2000s [2]. This progress has brought a number of countries to so-called pre-elimination status, and led the World Health Organization (WHO) and Roll Back Malaria (RBM) to revise their target to the new ambitious goal of reducing the global burden of malaria by 90% by 2030 [3, 4].

Entomological surveillance and monitoring are crucial to the different approaches developed through the WHO Global Technical Strategy towards malaria elimination [3]. Entomological and epidemiological data have highlighted resurgence in malaria transmission in several areas in SSA that had achieved high vector control coverage using ITNs and IRS [5,6,7,8]. For a long time, indoor chemical control tools have typically been the most effective against mostly endophagic and endophilic malaria vector species and populations [9]. Unfortunately, the efficacy of these tools is threatened because of the rapid evolution and spread of insecticide resistance in the main malaria vectors in many regions of SSA (Fig. 1a) [10, 11]. Worryingly, other studies have reported that resistant Anopheles phenotypes may be more susceptible to Plasmodium falciparum infection [12,13,14] highlighting another risk that could be linked with the escalation of pesticide-based indoor interventions. Beyond the insecticide resistance phenomenon, the selective pressures associated with pesticide exposure affect a large number of mosquito traits including behaviour, genetics, and physiology (Fig. 2). These parameters can affect the vectorial capacity and/or importance of anopheline vectors and are important determinants of local patterns of malaria transmission.

The selective pressures associated with indoor chemical vector control interventions affect many biological characteristics of mosquito populations and mosquito traits that affect vectorial capacity and malaria transmission. Upward arrows denote an increase in the trait considered

The most efficient malaria vectors in SSA, Anopheles gambiae, Anopheles coluzzii and some members of the Anopheles funestus group exploit larval breeding sites near human habitats and feed preferentially on humans. They are considered to be predominantly endophagic and endophilic [15] but these traits are somewhat plastic and levels of outdoor biting and resting vary between populations. There are also reports of An. gambiae (s.s.) populations with high levels of exophily that pre-date the intensification of chemical vector control [16, 17]. The sibling species, Anopheles arabiensis is known to frequently bite and rest outdoors [18]. In recent years, reports of behavioural shifts observed in response to intensified ITNs and IRS interventions have accumulated suggesting that they play an increasingly important role in malaria resurgence (Fig. 1b). Several studies conducted in SSA showed that An. arabiensis has replaced An. gambiae (s.s.) and An. coluzzii as the most dominant species following the intensifications of ITNs use [19,20,21,22]. Another study conducted in Kenya showed a shift in vector species with An. arabiensis and An. merus taking the place of An. gambiae (s.s.) and An. funestus as main malaria vectors [23]. In some regions, these populations now display behavioural avoidance, either through behavioural resilience or the evolution of behavioural resistance, towards indoor control tools such as actively seeking human hosts earlier at dusk and sometimes until dawn, feeding on non-human hosts, and increasingly resting outside. In Senegal, diurnal activity of An. funestus has been reported after the introduction of ITNs [24]. Another study in Ethiopia reported early evening activity by An. arabiensis with a peak activity between 19 and 20 h after the introduction of ITNs [25]. Earlier biting patterns might be concomitant with outdoor biting activities, as recently reported in Senegal in An. gambiae (s.l.) and An. funestus following two campaigns of ITNs renewal [26]. In Tanzania, An. arabiensis and An. funestus exhibited outdoor biting patterns, and were active early in the evenings after 47% of ITNs use [22]. Similar patterns were reported from a study testing the efficacy of outdoor landing boxes for anopheline control [27]. The tendency of outdoor biting was also described in the early morning hours in An. coluzzii and An. melas populations on Bioko Island [28]. This highlights the heterogeneity of Anopheles species and the predisposition of some vectors, such as An. arabiensis, to feed to an even higher degree outdoors and often on non-human hosts in response to the use of indoor vector control tools [29]. The result is that changes in vector behaviour, whether through resistance or resilience, are currently one of the most important challenges to malaria control, and alternative strategies to tackle outdoor populations at adult and immature stages need to be developed urgently.

Despite growing evidence of the importance of outdoor transmission, most tools for entomological surveillance and monitoring typically focus on indoor mosquito populations and may no longer be adequate for characterising the fast-changing composition and feeding behaviour. The human landing catches (HLC), which has long been the most efficient method of collection for anthropophilic endo- and exophagic vector species, is no longer possible in many regions [30, 31]. This method is based on capturers catching mosquitoes as they land on their exposed legs throughout the night, providing information on the timing of bites by local vector species. Understandably, the use of HLC has now been discouraged on ethical grounds as human-baits may not only be exposed to malaria vectors but, increasingly, to aedine mosquitoes carrying arboviruses for which prophylaxis or treatment is not yet available. Traps commonly used for monitoring indoors such as the Centre for Disease Control and Prevention light traps (CDC-LT) do not perform equally well for outdoor mosquito collections [32,33,34]. Indoor resting sampling by pyrethroid spray catch (PSC) is a commonly used tool that has no outdoor equivalent. Resting boxes, have long been used for indoors and outdoors monitoring [35] but their effectiveness outdoors varies greatly with the availability of natural resting sites, and seasonal factors, time of day, rainfall and humidity [36]. 006ab0faaa
