Transfer learning is a process of making tiny adjustments to a network trained on a given task to perform another, similar task. In our case we work with the ResNet-50 model trained to classify images from the ImageNet dataset. It is enough to learn a lot of textures and patterns that may be useful in other visual tasks, even as alien as this Alien vs. Predator case. That way, we use much less computing power to achieve much better result.
Almost all visual tasks benefit, to varying degrees, from data augmentation for training. For more info about data augmentation, see as applied to plankton photos or how to use it in Keras. In our case, we randomly shear, zoom and horizontally flip our aliens and predators.
AVP is officially a separate franchise and therefore a separate canon from Alien/Prometheus. Predator is also separate from AVP and Alien/Prometheus. If a Predator shows up in an alien project, that project is in the AVP universe and not Alien.
The frame rate is definitely higher in Phoenix, which I wouldn't mind trying, but I don't like the corrupted textures. I don't see any way to throttle performance in Phoenix. I had tried AvP in a different emulator that was so fast it was unplayable since the aliens moved at warp speed. I think Virtual Jaguar is the best for me. VJ seems maybe a little faster than hardware, but it doesn't feel it will affect gameplay.
More refined, contemplative, and formally inventive than Prometheus, and smoothed over with a gooey layer of sci-fi schlock right out of the early 50s. It's essentially Paul W.S. Anderson's The Thing From Another World; talkative, haunted by strange, triangular corridors and circular depths, and completely understanding of its own premise. Part H.P. Lovecraft, viscid horror, and 80s team-up videogame showdown, Alien vs. Predator flies past its own genre foundations as soon as it can, instead choosing to unleash stock (although memorable and never annoying) characters into macabre interiors festering with creatures and creepy crawlies. It's a blast from beginning to end, divulging fanboy dreams and playing with iconography while still remaining spooky and tangible (there's a flurry of practical effects here and they're all wonderful). Not quite my favorite W.S. Anderson film, but it's damn close. Practically an "At the Mountains of Madness" buddy picture. Flares and predators and facehuggers, oh my!
The devastating impact of alien predators on native wildlife within their new ranges [1], is often attributed to prey naiveté, or a failure to recognize and respond appropriately to a novel predation threat due to lack of experience [2], [3], [4]. Until recently, prey naiveté has been considered an all-or-nothing status, closely akin to island syndrome [2], [3]. Yet it is inarguably a more complex phenomenon, involving multiple levels through which native prey might progress towards predator-wariness [5], with each level closely tied to degrees of experience with a novel predator. It follows logically that alien predators cannot remain eternally novel; evolutionary theory predicts that prey species that do not become extinct must learn and adapt to new threats [6], [7], and there is recent evidence for this [e.g. 8]. According to some definitions [e.g. 9], [10], any species becomes irrevocably alien once it has been human-dispersed [11]. Yet the history of global biotic interchange, range expansion and natural dispersal shows that many native species were themselves once alien [12], and that adaptation and evolution will allow native communities to integrate many alien species, given sufficient time [6], [7], [13]. Naiveté of local species towards an alien threat cannot persist forever; therefore, alien status should not be considered immutable. In many cases, alien species will eventually become native. Despite an increasing focus on the effects of naiveté towards alien enemies soon after invasion [concentrated on], [ but not limited to predator]-[prey interactions; e.g. 2,4,14,15,16,17,18,19], the processes by which these novel ecological interactions between alien and native species develop and change in the medium to long term after establishment have received little attention [but see 13], [20]. As a result, one critical question remains unanswered: at what point after establishment and naturalization is an alien species sufficiently integrated into its new ecosystem to be considered native? We suggest that the logical, objective criterion that distinguishes this long-term change is the loss of ecological novelty, or in other words, the loss of naiveté of the alien species' native enemies in its new range.
Native bandicoots (Perameles nasuta) are vulnerable, critical weight range [24] marsupials that regularly emerge from bush land to forage in residential yards adjacent to national parks in Sydney. Foraging bandicoots leave behind characteristically deep, conical holes in lawns and gardens, which reliably indicate their presence [25]. C. familiaris and C. dingo are so closely related that they readily interbreed in the wild, and distinguishing between pure dingoes and wild dogs has become a conservation concern in Australia [26]. If long-term experience with an alien predator reduces the level of naiveté shown by native prey species, we would predict that bandicoots' far longer coexistence history with dingoes compared to feral cats should enable them to recognise the predation risk posed by domestic dogs but not cats. We therefore expected to see fewer and less frequent signs of bandicoot activity in yards with resident dogs than in yards with cats or no pets. To test this prediction, we assessed hundreds of replicates of predator presence or absence by surveying local residents to determine the level of visitation of bandicoots to their back yards. We compared responses from households without pets, to those with dogs or cats, whilst controlling for other variables such as yard size and accessibility. Our survey and analysis were designed to test whether Australian bandicoots remain naïve to dogs despite thousands of years experience with dingoes.
Just how much exposure to local enemies is necessary for an alien species to lose its novelty? The apparent lack of response to cats by bandicoots in our study suggests that for this particular pairing, hundreds of years of coexistence may not be enough. However, cats may pose different risks to dogs as they are more mobile and range past the boundaries of a particular yard, although their activity will be concentrated in that area. Experimental field manipulation of exposure to predators could examine this question.

Still set in our modern times, and therefore still happening before everything else in the Alien franchise, crossover sequel Aliens vs Predator: Requiem picks up right where AVP left off, with an Alien-Predator hybrid -- the "Predalien" -- now on the loose in a small Colorado town. A skilled, veteran Predator arrives to help clean up the mess and an ample amount of carnage ensues. This would be the final crossover film of the Alien franchise. 3. Prometheus (2012)Where to Watch: Hulu, Freevee, or rentable on most platforms.
Oscar-winning director Ridley Scott returned to the franchise he created in 1979 with the star-studded prequel film, Prometheus. Here, in the late 21st Century, Peter Weyland (presumedly a descendant of AVP's Charles Weyland, though the crossover Predator films are often treated separately) funds a cosmic trip into the unknown, following a star map left on Earth that might lead the crew of the Prometheus to the beings who created humankind. Sadly, the crew also stumbles across these creators' bio-weapon - the Xenomorph. Noomi Rapace, Michael Fassbender, Idris Elba, and Charlize Theron star. 4. Alien: Covenant (2017)Where to Watch: Rentable on most platforms.
Still in prequel mode here -- as Alien: Covenant is a sequel to Prometheus -- the story picks up 11 years later and follows a colonization ship whose crew gets pulled out of stasis years early and heads to a different target planet, a possible "utopia," to track down a distress signal. The downed ship emitting the message, however, is connected to the previous movie and contains all sorts of sinister things - ranging from Xenomorphs to androids. The film doesn't exactly take us up to the doorstep of 1979's Alien, as there's room for more story if deemed so, but it does get us close. Katherine Waterston, Billy Crudup, Danny McBride, Demián Bichir, and a returning Michael Fassbender star. 5. Alien (1979)Where to Watch: Starz apps and add-ons, or rentable on most platforms.
Space would never feel the same after Ridley Scott's landmark horror film, Alien, which featured the hardscrabble crew of a commercial space tug, the Nostromo, accidentally discovering a moon full of Xenomorph eggs. With no knowledge of what these creatures are, or how they cocoon inside humans before bursting out and rapidly growing into killing machines, these underpaid workers -- played by Tom Skerritt, Veronica Cartwright, Harry Dean Stanton, John Hurt, Ian Holm, Yaphet Kotto, and hero-in-the-making Sigourney Weaver -- find themselves going toe-to-toe with a cosmic nightmare. 6. Aliens (1986)Where to Watch: Starz apps and add-ons, or rentable on most platforms.
Terminator director James Cameron, before creating his own landmark sequel with T2: Judgment Day, gifted us with Aliens, taking the slow-boil brutality of the Ridley Scott original and ramping it up into a full-tilt masterpiece. Sigourney Weaver, returning as Ellen Ripley, would solidify herself as an action hero icon in this thrilling, endlessly-quotable film that would introduce the world to idea of space marines AND space marines getting their asses kicked, pal! Aliens would handily feature more than one Xenomorph (hence the plural title) as well as stars Michael Biehn, Bill Paxton, Paul Reiser, Lance Henriksen (who would play Charles Weyland decades later in AVP) and Carrie Henn. 7. Alien 3 (1992)Where to Watch: Starz apps and add-ons, or rentable on most platforms.
An appreciation for Alien 3 eventually bubbled up over the past 30 years but at the time David Fincher's directorial debut (three years before Se7en) would be deemed thin, grim, and, essentially, disappointing regarding Ripley's story (despite it giving us one of the most iconic images from the franchise, seen here). Alien 3 picks up right where Aliens left off, as the Colonial Marine spaceship, the Sulaco, is destroyed from within by a Xenomorph and an escape pod carries Ripley to a planet housing a penal colony. There, she and the inmates must deal with a rampaging alien before it massacres them all. 8. Alien Resurrection (1997)Where to Watch: Starz apps and add-ons, or rentable on most platforms.
The final film in the Ripley Saga, Alien Resurrection, hurls us 200 years beyond the events of Aliens and Alien 3 and into the inner workings of a military project aboard the USM Auriga that uses Ellen Ripley clones (and kidnapped humans) to try and successfully breed Xenomorphs. The City of Lost Children and Amélie's Jean-Pierre Jeunet directs this bizarrely-horrific chapter with cartoonish flare, casting Ron Perlman, Dan Hedaya, J. E. Freeman, Brad Dourif, and Michael Wincott as the story's new space grunts. The film ends with a possible tease of Xenomorphs headed to Earth, though we'd never get that story as a follow up (only in crossover prequel form with AVP).
